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.
