Terminal Specifications
ALM 12V7 s-Series batteries use copper terminals with tin plating. The terminals have a
maximum operating temperature rating of 90 °C. They are intended to mate with standard
female 0.25 inch (6,35 cm) “quick connect” terminals (TE Connectivity FASTON or
equivalent). Attach cable by inserting connector fully until the round locking detent has
engaged the center hole.
Configuring Batteries in Series Strings
To achieve higher operating voltages, arrange the ALM 12V7 s-Series batteries in series
strings by connecting the positive terminal of one battery to the negative terminal of the next
battery, as shown in
Figure 3 .
NOTE
The following battery string wiring examples provide general configuration information. Actual wire
configurations must be evaluated for their particular application.
The array voltage can be calculated as follows:
• Two batteries in series: 2 x 13.2 V = 26.4 V (nominal) for 24 V applications
• Three batteries in series: 3 x 13.2 V = 39.6 V (nominal) for 36 V applications
• Four batteries in series: 4 x 13.2 V = 52.8 V (nominal) for 48 V applications
The maximum number of ALM 12V7 s-Series batteries that may be connected in series is
four.
Figure 3 illustrates three ALM 12V7 s-Series batteries connected in a three-series, one-
parallel (3S1P) configuration.
