Battery Starting Systems
Battery starting systems for generator sets are 12 volt or 24 volt DC (Figure 16). When installing a battery system to start a generator set, consider the following:
See the Battery Safety Instructions on page 11.
Batteries must have enough capacity to provide the cranking motor current indicated on the genset specification sheet. The batteries may be either lead- acid or
A high output
For most emergency power systems, a
Local codes or site conditions may require battery heaters to maintain a minimum battery temperature of 50°F (10°C) if the battery is subject to freezing temperatures.
Standard gensets include battery racks and battery cables.
Battery cable resistance must not result in a voltage drop between the battery and the starter motor of more than 1 volt for 12 volt systems or more than 2 volts for 24 volt systems.

Electrolyte is an acid and must be handled with caution. Servicing instruction from the electrolyte manufacturer must ALWAYS be followed to ensure safety. Serious injury can result from careless handling and
Overfilling the battery may cause the electrolyte to overflow resulting in corrosion to nearby components. Immediately wash off any spilled electrolyte (battery acid). Additionally, when connecting the positive (+) cable to the battery's positive (+) terminal post, DO NOT allow contact of the wrench or any metallic object to come in contact with the battery's negative
