What are the different parts of a battery? A short summary:

--anode: the negative electrode during discharge. While charging, this becomes positive. In AA and AAA batteries, this is usually the protruding part on the top.
--cathode: the positive electrode during discharge. While charging, this becomes negative. In AA and AAA batteries, this is usually the flat part on the bottom.
--seal: a part of the battery cell that makes sure chemicals cannot leave the battery. It also limits air intake. A good seal is essential for a safe battery.

Technical battery terms explained
Whereas they're simple to use, the electrical processes are often a little more complex. Let's take a look at the most common technical battery terms used:
--capacity: the amount of energy that is stored inside a battery. It is measured in mAh (milliamp hours).
-- voltage causes electric charges to move through the wire or other conductors. It is measured in volt (V).
-- cycle: one sequence of charge and discharge, or: how many times you can use and recharge a battery. Every rechargeable battery has a set amount of cycles (i.e. cycle life) before it starts losing capacity and efficiency.

(In)correct battery usage
What about some less technical battery terms?
-- (self-)discharge, drain: discharge or drain happens when a battery loses energy. This ideally happens while it’s used in a device. However, a battery may lose (more) power when used incorrectly or when stored for longer periods of time. This depends on shelf life (see further).
--shelf life: the amount of time you can store unused batteries before they lose a significant amount of their capacity. For Godson batteries, batteries maintain up to 70% of their charge after 10 years.
--short-circuit: when electricity flows unintendedly, usually through a very short ‘path’, it will make the battery heat up and cause damage. Read more about battery safety here.
--memory effect: when a battery is discharged to the same ‘level’. For example: repeatedly discharging a battery to only 50% of its capacity before recharging it will cause the battery to lose some of its potentials. Luckily, there is no proven memory effect in Godson batteries.
