How long will the battery last?

There are two factors: runtime and charge-discharge cycles.

Runtime is a measure of how much time can elapse before a fully charged battery reaches a charge of 0%. Technically a battery never reaches a 0% charge but a low charge does not permit enough power to be transmitted to the device.

Runtime is controlled by capacity and usage. Capacity is measured in Amp hours or milliamp hours. Battery capacity quantifies the total amount of energy stored within a battery. More capacity equals longer runtime between battery charges. Hence if you want a battery to last the longest possible be sure to buy a battery with the highest possible capacity. For example a battery it a capacity of 2000 mAh will last longer in between charges than a battery with 1500 mAh capacity.

Runtime is also increased or decreased by usage.

All batteries slowly drain regardless if you are using it in your device or not! Once charged an electron flow occurs in a battery and once begun the electron flow will continue until the chemical is exhausted.

Chemical depletion occurs with every charge-discharge cycle. What is actually occurring during this charge-discharge cycle is replenishing spent electrons (i.e. creating current – an electrical flow)). In batteries electricity is created by charging two chemicals in a solution. This is done by applying an electrical flow (i.e. from a wall or car charger or solar charger) to the battery’s lithium.
