If you won't use the devices for a long time, it's suggested to remove the battery. Even when an electronic device is turned off, it will still discharge your battery over time regardless of the battery composition. It may cause the battery to over-discharge, which can result in the battery to expand, leak and possibly destroy the device.

Especially if they are alkaline batteries. Some of you at one time or the other have removed a battery compartment lid on alkaline batteries and seen the their leakage. Though, Li-ion batteries don't leak. While you still need to remove them from most devices just the same. That is because if there is any parasitic drain on them from the device, the batteries will completely discharge. If that happens, it will damage the batteries.

So the simplest way to prevent this from happening, is to remove the batteries from the device in time, and to store them properly.
