B. BATTERY CONNECTIONS
Here are some general guidelines regarding different types of battery connections:
• Series connections are used to increase battery voltage by connecting the positive terminal of
one battery to the negative battery of another battery. In this configuration, the overall capacity of
the battery is equal to the capacity of one battery. Series systems are wired as shown in Battery
Sketch 1.
PLEASE
NOTE:
When replacing multiple batteries, each battery should be of a similar
state of charge (SOC).
• Parallel Connections are used to increase the battery capacity by connecting the positive terminal
of one battery to the positive terminal of a second battery. Likewise, the negative terminals are
connected. In this configuration, the system voltage is the voltage of one battery. Parallel systems
are wired as shown below:
C. BATTERY CABLING
Since battery cables are the connection between the battery, the charging system and the device
being powered, it is important that they are properly installed. Improperly installed cables can result
in poor battery performance, terminal damage or even fire. Cables should be sized based on the
amount of current they are expected to carry in the application. Refer to Table 1 for cable current
ratings according to NEC Table 310.15(B)16 for copper cables rated at 167°F (75°C). If it is necessary
for a cable to be longer than six feet, a heavier gauge wire should be considered to avoid excessive
voltage drop.
