[Milsurplus] 3 types of Battery: Primary, Secondary & Reserve

[Gene Smar]

Gents:

     The "keep dry until used" type of battery was part of the proximity
fuze design in WW2.  I've read that the battery's electrolyte got mixed
among the layers of its positive and negative plates (helically wrapped
inside the fuze body) after the round had been fired out of the rifled gun
barrel and the projectile began its spiral journey towards its target.
Battery life needed to be - what? - five seconds at best?

     BTW - I also read that these little electronic gems were really rugged.
The force of firing was somewhere around 20,000Gs.  Imagine any of our
modern "smart phones" surviving that kind of abuse.

Hi:

There are three main battery classifications: Primary, Secondary
(rechargeable) and Reserve.

The idea pf the reserve battery is to keep the electrolyte separated until
the time of use.  The key benefit is a pretty much infinite shelf life.
