Overview
The term "battery" is a generic term for an elctro-chemical energy storage device.
The basis of all batteries is the electrochemical cell.
Technically, a "battery" is two or more electrochemical cells connected in series to create higher voltages than a single cell can provide (this term likely originates from artillery - an artillery battery is a group of guns). Most "batteries" are really cells.
Compatibility
Many lights have restricted compatibility with rechargeable batteries. Sometimes careful matching of a light with the appropriate rechargeable solution is required.
Corrosion
This term might need to be reviewed: there is chemical corrosion due to battery leakage, but - if I'm right - there are also effects that appear in electrical contacts: when opening/closing a contact, and when contacts are not totally "open" (or wide enough). Please correct this if I'm wrong.
- Leaving batteries in a flashlight will cause corrosion (term to be confirmed) in the contacts? Batteries should always be removed for long-term storage.
- Leaving batteries in any device is not recommended due to risks of battery leakage.
But I dare ask: if the switch is wide enough, is that still applicable? For example, Petzl e+lite has 10 yrs shelf life, this must mean that batteries may be left in. --axd 01:46, 18 April 2009 (MDT)
