Using Multiple Batteries
As your power requirements increase, you may need to use more than one
battery to obtain sufficient capacity. Read
and
to determine whether two
batteries or two battery banks are more appropriate for your applications.
Two Batteries Connected In Parallel
Two identical batteries can be connected positive (+) to positive (+) and
negative (–) to negative (–) in a parallel system. A parallel system doubles
capacity and maintains the voltage of a single battery.

shows a configuration that is recommended for heavy loads.
CAUTION
Do not connect the following in parallel: batteries made by
different manufacturers, different types of batteries, batteries
