Most of today’s devices are powered by battery.
The configuration inside one is various depending on load and capacity.
The most important to know is the way how a battery can be transported so it will not expand or cause fire.
They don’t like any form of a physical shock and pressure changes or high temperature.
Older models NiCd and NiMh had memory effect on the charging cycle.
that means each time you charge the cell it will be counted as one cycle.
The models after (NiCd, NiMh) don’t inherit this effect (Li-ion, Li-Polymer).
Important to know that the new models are not happy to be discharged to low.
Fully discharging some batteries can permanently damage them.
The best for them is to stay if possible above 30 to 50%.
