Think of it like cooking a meal: Using different ingredients and amounts makes the meal taste different. Batteries should be removed from devices/equipment when: the device is not expected to be in use for several months. The battery is worn out (to prevent possible damage from battery leakage). Only batteries that are specifically label' rechargeable' can be recharged. Store batteries in a dry place at normal room temperature without the contacts touching. Extreme heat or cold reduces battery performance. Avoid putting battery-powered devices in very warm places. In addition, refrigeration is not necessary or recommended.
