Batteries can be broken down
into 7 basic catagories
Lead acid: car batteries, ups
batteries, wheel chair batteries.
Carbon Zinc: general purpose
consumer batteries
Alkaline: heavy duty general
purpose consumer batteries
NIMH: Nickel Metal Hydride
rechargable batteries
NICAD: Nickel Cadmium
Rechargable Batteries
Lithium Ion: Generally cell
phone and portable device rechargable
battries.
Zinc Air: These are most
comonly used in hearing aids and medical
devices.
There are many places that will
pay for lead acid batteries. These are either sold
per battery or by the pound, and some places pay
up to $7.00 each for used car
batteries.

The Carbon Zinc, and
Alkaline batteries on the list are
usually used in consumer goods in the more
common sizes AAA, AA, C, D cell sizes. There are
exporters who will purchase these by the
ton.
The rechargable batteries NIMH,
NICAD, and Lithium ion, are mostly used in
portable electronic devices and power tools and
often may have to be removed from manufactured
plastic enclosures in order to be recycled. But
they have the best recyclable value. Some of the
metal alloys that make up these batteries
are expensive to manufacture, therefore new
battery makers will pay for this
material.
