Battery power explained

Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device. A high-capacity battery will be able to keep going for a longer period before going flat/running out of current. Some batteries have a sad little quirk—if you try and draw too much from them too quickly, the chemical reactions involved can''t keep

Unpacking the Power: The Math Behind How Batteries Work

Power, measured in watts (W), represents the rate at which energy is transferred or converted. Mathematically, power (P) is the product of voltage (V) and current (I): P = VI. Energy, on the other hand, is the capacity of the battery to do work and is measured in watt-hours (Wh) or joules (J). It''s calculated by multiplying power by time (t): E
