Description
Maximum Continuous Charge and Discharge Current to 100% at 25°C
a
a.
Continuous current (charge or discharge) is defined as occurring over a single full-charge or full-discharge cycle.
23 A (ALM 12V7s)
b
b.
Current that exceeds this value will be interrupted by the battery’s protection circuitry.
45 A (ALM 12V7s HP)

Maximum Pulse Charge and Discharge Current
For time-based-pulse current
limits, refer to
on page 28 and
Nominal Operational Voltage
13.2 V
Minimum Operational Voltage
8.0 V
Minimum Charge Voltage (for 10% State of Charge)
12.0 V
Maximum Charge Voltage (CC or CV)
16 V
Recommended Float Charge Voltage
13.6 V to 14.4 V
Nominal Capacity
5 Ah
Minimum Capacity at BOL
4.8 Ah
Maximum Ripple Current at low frequencies (60Hz/120Hz)
Peaks less than + 53 A and
average less than 23 A
c
c.
Although high ripple current at low frequencies (60Hz/120Hz) is not recommended, the ALM 12V7 s-Series battery will support
average ripple current with peaks up to 53 amps without any adverse effects. As a comparative example, the maximum ripple
current for a typical AGM (absorbent glass mat) 12 volt 7 Ah VRLA battery (@ 20hr rate) would be 7 Ah/20 hr or 0.35 amps.
