Do lithium batteries drain when not in use?

Yes, lithium batteries do drain when not in use, thanks to self-discharge. The rate of self-discharge depends on the battery's quality, age, and storage conditions. On average, lithium batteries lose about 2-3% of their charge per month when stored properly.

What happens if you don't use a lithium battery?

Capacity Loss: Over time, unused lithium batteries can lose their ability to hold a charge.

The passivation layer that forms on the electrodes can contribute to this loss of capacity.

What happens if a lithium battery is left in a deep discharge?

If a lithium battery is left in a discharged state for too long, it can fall into a deep discharge state.
