TERMINAL TORQUE SETTINGS
Calibrate the torque wrench before use to ensure accuracy. Terminal connections
should be tightened to 33 Nm or 25 lb-ft for all Flooded Series 4000, 4500 & 5000
models with lead terminals. Torque settings for VRLA AGM & OPzV GEL batteries
vary by terminal type. Please refer to the chart below and/or information provided
in the battery specifications. To prevent terminal damage, contact Rolls Battery
Technical Support for torque recommendations if your terminal type is not listed.

PARALLEL & SERIES CONNECTIONS
Applications often demand more voltage or more ampere capacity than the
capacity of one battery. By connecting multiple batteries of the same make/
model/capacity in series, parallel or series parallel configurations, output voltage
or battery bank amperage may be increased as needed.
To increase voltage, batteries are connected in series. Capacity of the battery
bank remains the same as voltage increases. To increase the available amount
of current and capacity, batteries are connected in parallel. In this situation it
is best to use lower voltage, higher capacity cells to minimize the amount of
parallel strings.
To increase voltage, connect the batteries in series as shown in Figure 1.
