Parallel
Series
When batteries are connected
in parallel, the battery amp hour
rating is additive, and the voltage
remains the same. Example:
Two 180 amp hour, 12 volt batteries
would equal 12 volts, and 360
amp hours capacity.
When batteries are connected in
series, the voltage is additive, and
the amp hour rating remains the
same. Example: Two 180 amp
hour, 12 volt batteries would equal
24 volts, and 180 amp hours of
capacity.

PROPER CARE AND USE OF BATTERIES:
CAUTION: Always wear protective eye shields and clothing when working with batteries.
Batteries contain acids which can cause bodily harm. Do not put wrenches or
Other metal objects across the battery terminal or battery top. Arcing or
explosion of the battery can result. Do not wear jewelry when working around
batteries. Arcing can cause sever burns.
New batteries will not deliver their full performance until after several cycles.
The tops of the batteries and battery hold downs must be kept clean and dry at all times to
prevent excessive self discharge and flow of current between the battery post and frame.
Maintain the proper electrolyte level by adding water when necessary. Never allow the
electrolyte level to fall below the top of the battery plates. Electrolyte levels fall during
discharge and rise during charging. Therefore, to prevent the overflow of electrolyte when
charging, add water ONLY AFTER the batteries have been fully charged DO NOT
OVERFILL. Old batteries require more frequent additions of water than do new batteries.
Do not over discharge the batteries. Excessive discharge can cause polarity reversal of
individual cells resulting in complete battery failure.
Provide adequate ventilation for the batteries and charger. Do not obstruct the flow of cooling air
around the charger. Provide at least 1" of space around charger. Do not allow clothing, blankets
or other material to cover the charger. Mount the charger firmly in place.
WARNING: Chargers can ignite flammable materials and vapors. Do not use near fuels,
grain, dust, solvents, or other flammable s.
CAUTION: Before connecting the charger to the batteries, make sure the battery pack is of
the same voltage rating of the charger. If you are unsure, count the number of
cells on the battery pack and multiply by two. This figure should be the same
as the DC voltage rating of the charger. (see ratings label on charger).
