Tips on Maintaining Lithium-Ion Batteries

Can lithium batteries go bad

Although lithium batteries have become the standard choice for storing solar-generated power, many homeowners are still doubtful about one thing: are lithium-ion batteries really maintenance free?

Homeowners looking for a hands-off approach to maintenance in their solar storage will surely find what they’re searching for in lithium-ion batteries. Still, the picture may not be as clear-cut as it may seem. In this article, the leading solar panel installers in Mira Mesa offer expert insight into lithium-ion batteries and their maintenance requirements. Read on!

Do lithium batteries go bad?

Thanks to the low maintenance requirements, high density, and falling costs of lithium-ion batteries, they have become the number one choice for solar storage in recent years. While they may not be the best fit where prolonged storage durations are needed, their perks definitely outweigh the drawbacks.

However, there is one thing to keep in mind when it comes to lithium-ion maintenance and that is the degradation rate. Just like any other lithium-ion battery, a solar battery will wear out after a certain number of charge/discharge cycles. Luckily, this degradation rate is usually planned for by battery manufacturers. In fact, many of them sell batteries that are rated to as many as 6000 cycles or more, which means that you won’t have to worry about your battery breaking down over the course of its lifespan (approximately 10 years or more).

How do I keep my lithium ion battery healthy?

Lithium-ion batteries are generally low-maintenance, although there are some slight differences between the two different lithium battery types. These are:

LFP batteries (lithium iron phosphate battery)

Lithium-iron phosphate batteries are designed to be long-lasting and safe for indoor applications, given that they don’t contain cobalt and pose no fire concerns. LFP batteries don’t require any maintenance, although the location of the installation may affect their functionality and performance.

Just like all lithium-ion batteries, LFP batteries have a BMS or battery management system which monitors the battery cells for state of charge, temperature, cycle life, and other parameters that can ensure proper performance.  The bottom line for LFP batteries is that they will be zero-maintenance as long as they are installed in suitable temperature ranges.

NMC batteries (lithium nickel manganese cobalt oxide)

NMC batteries are another safe and long-lasting option for solar home storage. The additionHow do I keep my lithium ion battery healthy? of manganese and nickel enables an NMC battery to store more energy than its competitors, and its battery management system ensures safe and efficient performance.

Just like other lithium batteries, NMC batteries require no maintenance. This is because their BMS monitors cell temperatures, voltages, and currents, and shuts down the entire system in the case of potentially dangerous operating conditions. This type of battery has no specific recommendations for winter usage, under the condition that the temperature ranges specified in the instructions are acknowledged. The LG Chem Resu is a good example of a quality NMC battery.
