What is a strap?
A stationary battery strap is a
component in a cell that joins
plates of like polarity in parallel.
It is an electrical conductor that
is made of copper. It typically has
a lead or tin plating for lead-
acid cells. Nickel-cadmium cells
require a different connector. They
are typically made with nickel-,
cadmium-, tin-plated copper,
or even steel bar. Occasionally,
the strap may be insulated with
copper wire or lead (with or
without a copper insert) for lead-
acid batteries, depending on the
manufacturer’s specifications.

Stationary batteries
Transportation batteries function
as start/stop batteries. The primary
discharge occurs when the vehicle
is started. After that, it spends the
rest of the drive time recharging.
