Top 8 Advantages of Lithium-Ion Batteries


Whether you need them for your golf cart, RV, or home or facility solar power array, you’ll need a battery (or batteries) that can provide plenty of power when and where you need it. When it comes to large batteries, you’re probably used to the old-fashioned lead-acid batteries in your car or another vehicle. Unfortunately, rechargeable lead-acid batteries have more minuses than pluses going for them. They need more time to recharge, are far less safe for the environment, and are more hazardous to use, for starters. Make the switch to lithium-ion batteries! When you go shopping for batteries, look for large lithium-ion batteries for sale. Here are the top eight advantages of lithium-ion batteries. 


One big advantage of lithium-ion batteries over lead-acid batteries is suggested by their names. As a denser substance, lead is far heavier than lithium, making lead-acid batteries an extra burden. That can significantly affect portability, maintenance, and performance, especially with vehicles. Be sure to take advantage of lithium-ion batteries’ lighter weight.

Less Maintenance

Everything needs some level of maintenance to work properly and provide great service. However, lithium-ion batteries need far less upkeep and fixing than lead-acid batteries while maintaining a high-performance level. In most cases, they need zero maintenance. Lead-acid batteries can leak, oxidize, and require periodic filling with distilled water. This is an inconvenient process, needing to be done only when the battery is fully charged. Because of their contents, lead-acid batteries also need to be kept from tipping and spilling. Lithium-ion batteries require no watering and don’t run the risk of splashing you with acid during maintenance. Lithium-ion batteries have other safety features as well, including what follows below.


While all types of batteries require a certain amount of protection from heat and overheating, lithium-ion batteries run fewer risks than lead-acid batteries. Lithium-ion batteries are designed with firmware known as a battery management system, or BMS, which monitors the charging process and keeps batteries working safely and at greater efficiency. Again, while all batteries need to be protected from overheating, lead-acid batteries generally don’t have a BMS to tip you off to potential hazards and the risk of explosion. Also, unlike lead-acid batteries, lithium-ion batteries are made of generally nontoxic substances. This allows you to store lithium-ion batteries without fear of a dangerous leak. 

Last Longer

Lithium-ion batteries are a bit more technologically advanced than lead-acid batteries. For example, they’re built to last longer, staying reliable even after thousands of cycles. Ostensibly, there’s no limit to the number of charges a lithium-ion battery can experience, retaining up to 80 percent of its original capacity and lasting up to 10 years or more. With proper care and regular recharging, lithium-ion batteries last far longer than lead-acid ones. BigBattery, for example, has a ten-year warranty on all batteries.

Costs More, But Worth It

Higher initial cost may sound more like a disadvantage, but with lithium-ion batteries, you get what you pay for and then some. While you may pay more for a lithium-ion battery, you’re not just buying the battery—you’re buying peace of mind, knowing it will last longer and provide more power than a lead-acid one. In fact, you might as well be throwing your money away with lead-acid batteries since you’ll have to replace them more frequently as they run out. Your overall cost over ten years is significantly less than with lead acid because you only buy a lithium-ion battery once for every 2 – 3 times you buy a lead acid battery. You should also keep in mind that as technology advances, costs go down, and lithium-ion batteries are already much less expensive than they were when they were first introduced.

Better Battery Capacity

Capacity refers to the amount of electricity, or current a battery can provide until its voltage drops to a certain level. Lithium-ion batteries have a higher capacity than lead-acid batteries. Lead-acid batteries need to be recharged before they drop to 50 percent capacity; otherwise the battery may be damaged and will lose capacity. Lithium-ion batteries, on the other hand, can drop to 20 percent capacity before needing a recharge. That means you get more hours of power out of them. Naturally, keep your batteries recharged, but rest easier with lithium-ion ones.

Less Risk of Overcharging

Leaving a lead-acid battery to charge for too long risks the possibility of overcharging. If left to charge for too long, the battery can overheat, increasing the levels of hydrogen and oxygen in the casing and producing dangerous levels of pressure. When that pressure is left unchecked and unreleased, the water inside can boil and leak, ruining the inner workings or even the battery itself and possibly leading to released toxic gases and an explosion. While lithium-ion batteries need to keep cool and shouldn’t be overcharged, the BMS keeps them within a safe range, as well as provides a protection circuit to prevent pressure buildup.

Fast Charging

Here’s the last of our top eight advantages of lithium-ion batteries—and it’s a big one! Lithium-ion batteries retain their charge for a longer period, but they also charge much more quickly than lead-acid batteries. They’re so efficient that they can be recharged within one to three hours. That means less downtime at work or play since you don’t have to wait as long for your source of power to come back online. Lead-acid batteries, on the other hand, take twice or even three times as long to charge. Rapid or incomplete charges also, as mentioned, can potentially ruin a lead-acid battery. Lithium-ion batteries, however, recharge in less time and at no risk to future capacity and effectiveness.
