What is an alkaline battery?	In the 1960s, this battery system rapidly became the popular choice of designers in the ever-widening field of consumer electronics.
Do all batteries last the same amount of time?	No, different batteries provide different lengths of life and power output depending on the type and amount of chemicals used to compose them. Think of it like cooking a meal: Using different ingredients and amounts makes the meal taste different.
What is inside a battery?	The three major parts of a battery: The anode, cathode and electrolyte. The anode is often a metal, the cathode a metallic oxide, and the electrolyte a salt solution that facilitates the ion flow.
When should I remove batteries from my device?	Batteries should be removed from devices/equipment when: The device is not expected to be in use for several months The batteries are worn out (to prevent possible damage from battery leakage) The device is being powered by household (AC) current.
Can alkaline batteries be recharged?	Only batteries that are specifically labeled ‘rechargeable’ should be recharged. Any attempt to recharge a non-rechargeable battery could result in rupture or leakage. We recommend that you use NiMH Amazon Basics rechargeable.
Does it matter what type of battery I use in my device?	Always replace the battery or batteries in your equipment with the size and type specified by the manufacturer. Alkaline batteries are often recommended for best performance because zinc carbon batteries have inferior life spans.
How can I get a better life out of my batteries?	Turn off battery-operated radios and appliances when they’re not in use. Remove batteries from devices that won’t be used for a while. Store batteries in a dry place at normal room temperature without the contacts touching.
Are batteries affected by temperature?	We recommend storing batteries at room temperature in a dry environment. Extreme heat or cold reduces battery performance. Avoid putting battery-powered devices in very warm places. In addition, refrigeration is not necessary or recommended.
