or other liquids. Only recharge the battery pack strictly according to instructions
included in the product documentation.
Battery abuse or mishandling can cause the battery to overheat, which can cause
gasses or flame to "vent" from the battery pack or coin cell. If your battery is
damaged, or if you notice any discharge from your battery or the buildup of foreign
materials on the battery leads, stop using the battery and obtain a replacement
from the battery manufacturer.
Batteries can degrade when they are left unused for long periods of time. For
some rechargeable batteries (particularly Lithium Ion batteries), leaving a battery
unused in a discharged state could increase the risk of a battery short circuit,
which could shorten the life of the battery and can also pose a safety hazard. Do
not let rechargeable Lithium-Ion batteries completely discharge or store these
batteries in a discharged state.
