How long do deep cycle batteries last

Imagine it is a stormy Tuesday night. The wind is howling outside, rain is lashing against the windows, and suddenly, the neighborhood goes dark. The streetlights flick off, and your neighbors’ houses fade into the gloom. But at your house, something different happens. Maybe the lights flicker for a split second, or maybe they don't blink at all. Your refrigerator keeps humming, your internet router stays online, and you can still charge your phone. This isn't magic; it is the result of a well‑planned energy storage system. And at the very center of that system, doing all the heavy lifting, is your battery bank.
For many homeowners in the United States, solar power started as a way to save a few dollars on the electric bill or to be a little greener. But as weather gets more unpredictable and power outages become more common, the focus has shifted. Now, it is about independence. It is about keeping the lights on when the grid goes down. Solar panels are great, but they have one big flaw: they only work when the sun is shining. To bridge the gap between a sunny afternoon and a dark, stormy night, you need a way to store that energy. You need a deep cycle battery.
This guide is going to take a deep dive into the world of deep cycle batteries. We aren't just going to look at spec sheets and numbers; we are going to talk about what it is actually like to live with these batteries. We will look at how long they really last, how they handle freezing cold winters and scorching hot summers, and what you actually have to do to keep them running. Whether you are looking to back up a sump pump in a basement in Ohio or run an entire off‑grid cabin in Arizona, understanding your battery is the key to not getting left in the dark.
We will compare the old‑school heavyweights—Lead‑Acid batteries—against the modern high‑tech challengers—Lithium Iron Phosphate batteries. We will break down the chemistry into plain English, explain why "100 amp‑hours" doesn't always mean "100 amp‑hours," and look at the real costs over ten years, not just what you pay at the checkout counter today.

2. The Basics: What Makes a Battery "Deep Cycle"?

Before we can pick a winner, we have to understand the game. You might be wondering, "Why can't I just use a bunch of car batteries? They are cheap and available everywhere." It is a fair question, but the answer lies in how the battery is built on the inside.

2.1 The Sprinter vs. The Marathon Runner

Think of a standard car battery—the kind under the hood of your sedan—as a sprinter. Its job is to give a massive burst of energy for just a few seconds to start the engine. Once the engine is running, the alternator takes over, and the battery rests. To do this, car batteries are made with lots of very thin lead plates. These thin plates have a ton of surface area, which allows them to release a lot of power instantly. But there is a catch: those thin plates are fragile. If you try to run your TV or lights off a car battery and drain it down until it's empty, those thin plates will start to disintegrate. Do that a few dozen times, and the battery is dead.1
A deep cycle battery is different. It is the marathon runner of the battery world. Instead of thin sponge‑like plates, it uses thick, solid lead plates (in lead‑acid versions) or robust chemical structures (in lithium versions). These batteries are designed to provide a steady amount of power over a long period—hours or even days. More importantly, they are designed to be drained down (discharged) and filled back up (recharged) hundreds or thousands of times. This process is called "cycling." A deep cycle battery doesn't mind working hard all day, whereas a car battery would burn out after just a few deep workouts.2

2.2 The Main Contenders

When you go shopping for a home battery today, you are primarily looking at three main types. Let's introduce the players.
1. Flooded Lead‑Acid (FLA): The Old Faithful
This is the technology that has been around for over 150 years. If you have ever looked under the seat of a golf cart, you have probably seen these. They look like black plastic boxes with removable caps on top. Inside, lead plates are submerged in a liquid mixture of sulfuric acid and water (electrolyte).

The Vibe: They are heavy, they slosh when you move them, and they are the cheapest option upfront.3
The Catch: They are needy. You have to check the water levels regularly and top them off with distilled water. If you forget, they die.4

2. Absorbent Glass Mat (AGM): The Low‑Maintenance Cousin
AGM batteries are a newer version of lead‑acid. Instead of liquid sloshing around, the acid is soaked into fiberglass mats that are squished between the lead plates.

The Vibe: They are sealed tight.5
The Catch: They cost more than flooded batteries and generally don't last quite as long in deep cycling roles, but they save you the hassle of maintenance.6

3. Lithium Iron Phosphate (LiFePO4): The Smart Upgrade
Often just called "Lithium" or "LFP," these are the modern standard. Note that these are not the same dangerous lithium batteries found in cell phones or hoverboards that catch fire. LiFePO4 is a very safe, stable chemistry.

The Vibe: They are incredibly light—about half the weight of a lead battery. They are "smart" because they have a computer inside called a Battery Management System (BMS) that protects them.7
The Catch: The price tag. They can cost two to three times as much as a lead‑acid battery upfront, which gives many homeowners sticker shock.8

3. Duration: How Long Will It Really Last?

When we talk about "duration," we mean two things. First, how many years will the battery last before you have to throw it away? Second, how long will it run your lights during a power outage? Let's break these down, because the numbers on the sticker don't always tell the whole story.

3.1 The "Cycle Life" Reality

Every battery has a finite number of "cycles" in it. Think of a battery like a tire. Every mile you drive wears a little bit of rubber off. Eventually, the tread is gone. For a battery, every time you drain it and charge it, you use up a little bit of its life. But here is where the difference between Lead‑Acid and Lithium gets massive.

The Lead‑Acid Lifespan: A standard flooded lead‑acid battery might be rated for about 300 to 700 cycles. If you use it every single day (like in an off‑grid solar home), that is only about one to two years of life. Some high‑end premium models can reach 1,000 cycles, but that is the exception, not the rule.9
The Lithium Lifespan: A LiFePO4 battery is typically rated for 3,000 to 7,000 cycles. Even on the low end, that is ten times the lifespan of a basic lead‑acid battery. If you cycle it once a day, a lithium battery could theoretically last 10 to 20 years. This huge gap is the main reason why lithium is becoming so popular, despite the high price.10

3.2 The Depth of Discharge (DoD) Trap

This is the most important concept for a homeowner to understand. It is the "Gotcha!" of the battery world. Depth of Discharge (DoD) is simply how much energy you take out of the battery. If you have a full battery and you use half of its energy, you have done a 50% DoD.
The 50% Rule for Lead‑Acid:
Lead‑acid batteries are fragile when they get empty. If you drain a lead‑acid battery down to 0% (totally dead), you cause permanent, irreversible damage. To make them last a decent amount of time, manufacturers and experts have a golden rule: Never discharge deeper than 50%.
This means if you buy a battery that says "10 kWh Capacity," you can really only use 5 kWh of it. If you use more, you drastically shorten the battery's life. You are effectively paying for a full bucket but are only allowed to use the top half of the water.11
The Lithium Freedom:
Lithium batteries don't play by these rules. You can safely discharge them to 80%, 90%, or sometimes even 100% without killing the battery. Most experts recommend staying around 80% DoD to get the maximum life (those 5,000+ cycles), but if you have an emergency and need to drain it to zero, the battery will wake up the next day and be fine.
This means a "10 kWh" lithium battery actually gives you about 8 to 10 kWh of usable power. You get to use almost the whole bucket.12

Feature	Lithium (LiFePO4)	AGM / Lead‑Acid
Total Cycles	3,000 to 7,000+	300 to 700
Usable Capacity	80% to 100%	50% Recommended
Years of Daily Use	10+ Years	2 to 4 Years
Weight per 100Ah	~30 lbs	~65 lbs

3.3 The "Peukert Effect" (Or, Why Your Battery Dies Fast When You Use the Microwave)

Have you ever noticed that if you run (sprint), you get tired much faster than if you walk, even if you are covering the same distance? Batteries are similar.
If you have a lead‑acid battery and you run just a few LED lights (walking), the battery will last a long time. It gives you its full capacity. But if you turn on the microwave, the hair dryer, and the well pump all at once (sprinting), the battery gets "tired" incredibly fast. This is called the Peukert Effect.
Lead‑acid batteries have high internal resistance. When you try to pull a lot of power out quickly, a lot of that energy gets wasted as heat inside the battery instead of powering your house.

The Math: A 100 Amp‑hour lead‑acid battery might give you 100 Amp‑hours if you sip the power slowly over 20 hours. But if you try to pull that power out in just 1 hour, you might only get 50 or 60 Amp‑hours. You effectively lose almost half your battery capacity just because you are using high‑power appliances.13

Lithium batteries are different. They have very low internal resistance. They are like marathon runners who can sprint without getting winded. Whether you sip the power slowly or drain it quickly with heavy appliances, a lithium battery gives you almost the same amount of energy (about 98% efficiency). If you plan to run heavy loads like power tools, microwaves, or air conditioners, lithium is practically mandatory because lead‑acid just can't keep up with the pace.14

4. Battling the Elements: Performance in Extreme Weather

Unless you live in a climate‑controlled laboratory, your batteries are going to experience weather. Maybe they are in a garage that freezes in winter, or a shed that bakes in the summer. Temperature is the single biggest environmental factor that changes how your battery behaves.

4.1 Freezing Cold: The Winter Slump

Batteries are chemical reactions in a box. Just like molasses moves slower in January, chemical reactions slow down when it gets cold.
Lead‑Acid in the Cold:
Lead‑acid batteries are tough. They can survive freezing temperatures, but they get sluggish. At 32°F (freezing), a lead‑acid battery loses about 20‑30% of its capacity. If it gets down to 0°F (‑18°C), you might only have 45% of your battery power available. The lights will be dimmer, and the battery will die much sooner than you expect.15

The Danger Zone: There is a hidden danger with lead‑acid in winter. The liquid inside a fully charged battery is strong acid, which freezes at a very low temperature (around ‑75°F). But as the battery drains, that acid turns into mostly water. If you have a dead lead‑acid battery sitting in a freezing garage, the liquid inside can freeze at just 20°F. When water freezes, it expands. This can crack the plastic case of the battery. When it thaws, you will have a puddle of acid on your floor and a ruined battery.17

Lithium in the Cold:
Lithium batteries handle the cold discharge better. At 0°F, a lithium battery can still give you about 60‑70% of its power. The voltage stays higher, too, so your appliances run better.15

The Lithium Achilles Heel: There is one massive rule for lithium: Never CHARGE a lithium battery below freezing (32°F). You can use (discharge) it, but if you try to force energy into it while it is frozen, you cause permanent damage (called lithium plating). The battery might die instantly or short out later.
The Solution: Good lithium batteries have a "Smart" BMS that will automatically stop charging if it gets too cold. The really good ones have built‑in heating pads. When you plug them in, they use the electricity to warm themselves up first, and only start charging once they are safe. If you live in a cold climate, you absolutely need self‑heating batteries or an insulated battery box.19

4.2 Scorching Heat: The Silent Killer

While cold makes batteries slow, heat makes them age faster. Heat is actually worse for the long‑term health of a battery.

Lead‑Acid and the "Half‑Life" Rule: There is a rule of thumb for lead‑acid batteries: for every 18°F (10°C) you go above 77°F, you cut the battery's life in half. So, if your battery is rated to last 4 years at 77°F, but it sits in a Florida garage that averages 95°F, it might only last 2 years. The heat causes the grid inside the battery to corrode and the water to evaporate faster.19
Lithium's Heat Tolerance: Lithium batteries are much tougher in the heat. They can operate safely up to 140°F (60°C). While heat isn't good for them, they don't die nearly as fast as lead‑acid batteries do in hot weather. A lithium battery at 130°F can often last twice as long as a lead‑acid battery at room temperature.20

5. The Real Cost: A 10‑Year Financial Breakdown

One of the hardest parts of buying a solar battery system is the sticker shock. You look at a lead‑acid battery for $200 and a lithium battery for $800, and your wallet screams "Lead‑Acid!" But let's look at the math over 10 years. This is where the "Duration" part of our report really matters.
Let's assume you need a battery bank for a small off‑grid cabin or a home backup system. You need about 5 kWh of usable power per day.
Scenario A: The Lead‑Acid Route
To get 5 kWh of usable power, you can't just buy a 5 kWh battery. Remember the 50% Rule? You have to buy a 10 kWh battery bank so you can use half of it safely.

Upfront Cost: A decent 10 kWh AGM lead‑acid bank might cost around $2,000.
Lifespan: Because you are using it every day, it will last about 500 cycles, or roughly 2 to 3 years.
Replacement: Over a 10‑year period, you will have to buy and replace that battery bank at least 3 or 4 times.
Total Cost over 10 Years: $2,000 x 4 replacements = $8,000 (plus the hassle of hauling heavy batteries every few years).21

Scenario B: The Lithium Route
To get 5 kWh of usable power, you can buy a 6 kWh lithium bank because you can safely use 80% of it.

Upfront Cost: A decent 6 kWh LiFePO4 bank might cost around $2,500.
Lifespan: This battery is rated for 5,000 cycles. That is more than 13 years of daily use.
Replacement: You buy it once. It lasts the whole decade.
Total Cost over 10 Years: $2,500.

The Verdict:
While the lithium battery costs slightly more on day one, it ends up being $5,500 cheaper over the decade. This calculation doesn't even include the cost of electricity. Lithium is 95% efficient, while lead‑acid is only 80% efficient. That means with lead‑acid, you are wasting 20% of the solar power you generate just trying to push it into the battery. Over 10 years, that wasted energy adds up to real money.21
Wait, is Lead‑Acid ever the right choice?
Yes! If you are building a backup system for a hunting cabin you only visit twice a year, lithium is a waste of money. A battery ages simply by sitting there (calendar aging). A lithium battery might die of old age in 15 years even if you only used it 20 times. For rarely used systems, cheap lead‑acid batteries make perfect financial sense.

6. Maintenance: The "Chore Chart"

This is the part that usually seals the deal for people. How much work do you want to do?

6.1 Living with Flooded Lead‑Acid

Owning a flooded lead‑acid battery is like having a pet. You have to take care of it, or it will get sick. Here is your monthly checklist:

Safety First: Put on safety goggles and rubber gloves. You are dealing with sulfuric acid. Wear old clothes because if a drop gets on your jeans, it will eat a hole in them.23
Check the Water: Pop the caps off the top of the battery. Look inside. Is the liquid covering the lead plates? If not, the plates are exposed to air and are permanently corroding.
Add Water: Use only distilled water. Not tap water (the minerals will kill the battery). Pour it carefully to the fill line. Do not overfill, or acid will bubble out when it charges.4
Cleaning: Mix baking soda and water to make a paste. Scrub the battery terminals to remove that crusty white corrosion. This is messy.24
The "Equalization" Charge: Every few months, you need to deliberately overcharge the batteries to boil the acid and mix it up. This smells like rotten eggs (sulfur) and releases hydrogen gas, which is explosive. You need to make sure your battery box is vented to the outside.25
Testing: To really know if your battery is healthy, you need a tool called a hydrometer. You suck up some acid and see if a little floaty bobber floats. It is scientific, but it is a hassle.23

6.2 Living with Lithium

Owning a lithium battery is like owning a smartphone.

Check the App: Most modern lithium batteries have Bluetooth. You open an app on your phone. It tells you "98% Charged."
That's it. There is no water to add. There is no acid to check. There is no corrosion to scrub. The internal computer (BMS) balances the cells automatically. You can install them and basically forget they exist.2

7. Safety and Environment: What's in the Box?

7.1 Safety Risks

Lead‑Acid: The main risks are acid spills and gas. As mentioned, charging lead‑acid batteries releases hydrogen gas. If you put these batteries in a sealed closet without ventilation, a spark could cause an explosion. They are also incredibly heavy (60‑70 lbs for a standard unit), which leads to back injuries during installation.1
Lithium (LiFePO4): These are very safe. They don't release gas, so you can install them anywhere inside your house (even under a bed or in a closet). They are much lighter (about 30 lbs). The chemistry is stable, so unlike the battery in your laptop, these won't catch fire even if you puncture them.6

7.2 Recycling and the Environment

This is the one area where Lead‑Acid is the undisputed champion.

The Recycling King: Lead‑acid batteries are the most recycled consumer product in America—more than aluminum cans or glass bottles. About 99% of lead‑acid batteries are recycled. When you turn in your old battery to buy a new one (the "core charge"), that old battery is broken down. The plastic case becomes a new case, the acid is treated, and the lead is melted down to make new plates. A new lead battery is made of 80% recycled material. It is a perfect closed loop.29
The Lithium Challenge: Lithium recycling is still catching up. Right now, only a small percentage (around 15‑20%) of lithium batteries are recycled, although this is growing fast as electric cars become popular. While LiFePO4 is less toxic than other lithium types (no cobalt or nickel), the industry hasn't quite figured out how to make recycling them as profitable and easy as lead‑acid yet.31

8. Buying Guide: What to Look For

So, you are ready to buy. Here is what you need to look for on the spec sheet to make sure you aren't getting ripped off.

8.1 Decoding the Label

Amp‑Hours (Ah): This is the size of the gas tank. Common sizes are 100Ah or 200Ah. Remember, 100Ah of Lithium is worth about 200Ah of Lead‑Acid due to the depth of discharge rules.
Voltage: 12V is standard for smaller systems (RVs, vans). 24V or 48V is better for whole‑home solar because it is more efficient and uses thinner wires.13
"C‑Rate" or Max Discharge Current: This tells you how fast you can drain the battery. If a 100Ah battery has a "1C" rating, you can pull 100 amps at once (great for microwaves). If it has a "0.5C" rating, you can only pull 50 amps. Make sure this number is high enough to run your biggest appliance.19
Cycle Life Warranty: Look for the warranty fine print. A cheap battery might offer a "10‑year warranty" but only cover 2,000 cycles. A quality battery (like Battle Born, SOK, or Trojan) will cover 3,000‑5,000 cycles. Also, check if the warranty is "prorated" (meaning they pay you less as the battery gets older) or "full replacement".33

8.2 Brand Matters

Budget Lead‑Acid: Brands like Interstate or generic "Marine" batteries at big‑box stores. Good for starters, but don't expect long life.
Premium Lead‑Acid: Brands like Trojan or Rolls/Surrette. These are legendary for durability. A Trojan T‑105 golf cart battery is the "gold standard" for DIY solar on a budget.3
Premium Lithium: Brands like Battle Born, Victron, or Discover. These are expensive but have incredible build quality, verified specs, and US‑based support. They often have built‑in heaters for cold weather.33
Budget Lithium: There are many cheaper brands on Amazon (like LiTime or Chins). They are often good value, but they usually lack low‑temperature protection (you have to be careful in winter) and customer support can be spotty.37

9. Seasonal Checklists: Keeping Your System Alive

To wrap up, here is your cheat sheet for keeping your batteries happy through the year.

Spring Cleaning Checklist

Lead‑Acid: Check water levels. Clean the green/white corrosion off the terminals with baking soda. Tighten all the bolts (they can loosen up as temperatures change).
Lithium: Check the app to see if the cells are balanced. Visually inspect wires for any mouse chewing or wear.38
Solar Panels: Pollen season! Wash your solar panels with water and a soft sponge. Dirty panels mean less power to charge your batteries.38

Winter Prep Checklist

Insulation: If your batteries are in a garage, wrap them in insulation or build an insulated box.
Lead‑Acid: Make sure they are 100% fully charged before a big freeze. Remember, a dead lead battery freezes at 20°F and will crack. A full one is safe to ‑75°F.
Lithium: If you don't have heated batteries, make sure your charge controller is set to stop charging if the temp drops below 32°F. Double‑check your settings.18

10. Summary Table: At a Glance

Feature	Flooded Lead‑Acid	AGM Lead‑Acid	Lithium (LiFePO4)
Best For...	Extreme budget, rarely used cabins	Low maintenance, vibrations (RVs)	Daily solar, long‑term homes
Upfront Cost	$ ($150‑$200)	$$ ($250‑$400)	$$$ ($600‑$1,000)
Maintenance	High (Watering, Venting)	Low (Keep charged)	Zero (Check App)
Lifespan	2‑4 Years	3‑5 Years	10+ Years
Usable Power	50% of rating	50% of rating	80‑100% of rating
Winter Risk	Freezing & Cracking	Low	Can't Charge <32°F
Weight	Very Heavy	Heavy	Lightweight

Conclusion

Choosing a battery is less about "which is best" and more about "which is best for you."
If you are on a tight budget and don't mind getting your hands dirty with a little maintenance, a classic set of Trojan T‑105 lead‑acid batteries is a proven, rugged way to get started. They have powered off‑grid cabins for decades and will treat you well if you treat them well.
But for most modern homeowners who want a system that "just works," Lithium (LiFePO4) is the new champion. The ability to use all the power you pay for, the 10‑year lifespan, and the freedom from maintenance chores make them the cheaper option in the long run. They turn your energy system from a hobby you have to manage into a utility you can rely on.
Whichever path you choose, treat your batteries with respect. Keep them within their temperature limits, don't drain them too flat (especially lead‑acid!), and they will keep the lights on when the rest of the world goes dark.
