Battery Types

** There are two classes of cells ( the term battery refers to more than one) - primary and secondary.

The former are non-rechargeable.

The cells popularly known as " alkalines" are primary cells.

** The topic cells and batteries is huge and endless.

Much published data is misleading and/ or has important details missing.

The chemical industry ( who design and make all batteries) is very secretive.

And the ones called "rechargeable alkalines" should really be called "kinda rechargeable alkalines"...

Radio Shack used to have a book with discharge curves for most of the batteries that they sell, and with recommended applications. For rat shack it was beyond top quality (i.e. it's actually somewhat useful).

Gates Enercell has a book called something like "Rechargeable Battery Handbook" (maybe I'll look at my copy). It looks like a very authoritative guide to using nickle-cadmium and lead-acid batteries -- at least the few times that I've used it it hasn't steered me wrong.
