Today’s rechargeable batteries have become better than ever! Almost every gadget we use has them and are an integral part of our daily tasks. Small devices like mobile phones, remote, drones, cameras and more depend entirely on Lithium-ion batteries. The power pack works fine up to 1 year or more, if and when used appropriately. However, it’s time to take a look at how long rechargeable batteries last and are they better than traditional lead-acid batteries?
A lithium battery, which is also referred to as a lithium-ion (Li-ion) battery, is a battery that incorporates the mineral Lithium as a key component in its structure. These batteries are recognized for being lightweight and having extended lifespans, and they find utility in numerous applications such as mobile phones, laptops, electric vehicles, and solar power generation.
Some popular types of Lithium Batteries are:
Lithium Iron Phosphate LFP (LiFePO4)
Lithium Cobalt Oxide LCO (LiCoO2)
Lithium Manganese Oxide LMO (LiMn2O4)
Lithium Nickel Cobalt Aluminium Oxide NCA (LiNiCoAlO2)
Lithium Nickel Manganese Cobalt Oxide NMC (LiNixMnyCozO2)
Since the mid twentieth century (1960’s-70’s) the lithium-ion battery has undergone many advancements in terms of lifespan, cost, energy density, and more.
In solar energy circles, EVs and energy storage Lithium Iron Phosphate LFP (LiFePO4) is used. They have been recently introduced in the industry and have taken the market by storm. In the shortest span of entering the market, they are already considered superior to the lead-acid batteries.
An LFP or LiFePO4 stands for lithium iron phosphate. If you are wondering where the ‘F’ comes from. It comes from Ferrum, the Latin word for Iron. LFP batteries have a Lithium Iron Phosphate cathode and Graphite anode, which gives them a lower energy density in exchange for increased safety and better performance in other aspects such as discharge rate.
Lithium batteries generally last longer and perform better than other types of batteries. Like lead-acid batteries, for example. Lithium batteries currently have the longest lifespan of all available deep-cycle batteries. Many have the ability to last between 3,000-5,000 partial cycles. For comparison, lead-acid batteries typically give 500 -1,000 partial cycles.
Partial cycles refer to draining the battery and then recharging it. If you charge the battery and then discharge it at half its capacity, that would be a half cycle. Let’s consider a side-by-side or boat powered by a lithium battery that’s recharged once a day. This means that the battery should last for more than 3,000 days, which is over eight years. Which is a fantastic lifespan! By doing a few calculations, you can get a better feel for how long lithium batteries can last for you.
Of course, the lifespan of LiFePO4 batteries can vary depending on several factors. To get the most bang for your buck, you may consider these factors when taking care of your batteries:
Temperature - High temperatures can reduce the lifespan of your LiFePO4 batteries. On the flip side, low temperatures can decrease their performance. Thankfully, these are some of the hardiest batteries out there and can operate at -20~60℃ or -4℉~140℉.
Overcharging - With both lithium and lead-acid, damage can occur to the battery and shorten its lifespan, if you overcharge. That’s why having a BMS (battery management system) is crucial. Here at IB Energy, all of our batteries come equipped with one.
Storage Conditions - Ideally, LiFePO4 batteries should be stored in a cool, dry place to avoid degradation of the battery’s chemistry.
Cycle Life - The number of charging and discharging cycles that your battery goes through will affect its lifespan. Generally, a higher cycle life battery will have a longer lifespan. This is where lithium really shines with its 3,000 – 5,000 partial cycles, on average. It’s designed to be used for many many years!
Overall, the lifespan of LiFePO4 batteries is dependent on several factors, and proper care and maintenance can help prolong their lifespan. But if you’re looking for the best Lithium-ion battery that’s more “leave it and let it be” then this is it! It’s about as maintenance-free as you can possibly get.
Lithium batteries have a much higher energy density when compared to other batteries. This means they store more energy than other batteries. They also come in smaller, lighter packaging. For these reasons, they really are the gold standard for deep-cycle batteries. They match many users’ on-the-go lifestyles and perform for hours without recharging.
We can do some things to make our lithium batteries last longer though. This will improve the device’s performance and how long it can hold its charge throughout the day.
Lithium batteries can take a close to full depth of discharge (90% DOD) safely, unlike lead acid. But, it’s best to avoid completely draining the battery to prolong its life. Avoiding this will increase the longevity of a lithium battery.
Lithium batteries are already the go-to choice for many, but their rise in popularity is growing. In fact, the best lithium-ion batteries manufacturers are in India. Their widespread use is because of their high energy density, fast charging, and long lifespan.
They are also safer than other types of rechargeable batteries. This makes them ideal for e solar power setups, work equipment, lawnmowers, and other commonly used devices.
When you consider efficiency, reliability, and lifetime costs, it’s clear that lithium batteries are superior. While they may cost more upfront than other types, the long-term savings far outweigh the initial expense.
We hope you found the information and tips in this blog post on how long lithium batteries last helpful. Now you can prolong the life of your LiFePO4 battery and get the most out of it for years to come!
