Do lithium ion batteries need to be drained?

To ensure the longevity of lithium-ion batteries, it’s important to avoid both deep discharge and overcharging. Deep discharge occurs when a battery is drained to nearly zero, which can cause the battery’s internal voltage to drop too low, damaging the cells and making the battery unsafe or impossible to recharge.

How to store a lithium battery?

When it comes to storing lithium batteries, taking the right precautions is crucial to maintain their performance and prolong their lifespan. One important consideration is the storage state of charge. It is recommended to store lithium batteries at around 50% state of charge to prevent capacity loss over time.

Can you store lithium ion batteries at full charge?

No, it is recommended to store lithium-ion batteries at around 40-60% charge. Storing batteries at full charge can cause stress on the internal components, accelerating degradation. On the other hand, storing them completely discharged can result in deep discharge, which may damage the battery and make it difficult to recharge.

How do you store half-used batteries?

When you take half-used batteries out of seasonal devices like holiday lights or camping gear, store them in a way that keeps them separate from unused batteries to avoid confusion. It also helps if new batteries are left in their original packaging. Speaking of which

Can lithium ion batteries be stored in the refrigerator?

Storing lithium-ion batteries in the refrigerator or freezer is not recommended. Extreme cold can damage the battery’s internal chemistry and cause the electrolyte to freeze, which could reduce capacity and efficiency. Additionally, the condensation that forms when moving the battery from cold to warmer environments can cause moisture damage.

Can you store a battery in a plastic bag?

As easy as it may be to have a dedicated “battery drawer” or to store loose batteries in a plastic zipper bag together, it’s not a great idea. Batteries can easily come into contact with each other, which can cause a short circuit, or at the very least cause them to discharge and become drained.
