Maximum Ripple Current at low frequencies (60Hz/120Hz)
a.
Continuous current (charge or discharge) is defined as occurring over a single full-charge or full-discharge cycle.
b.
Current that exceeds this value will be interrupted by the battery's protection circuitry.
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.
