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.
Charge sources exceeding the continuous current will charge the battery at a duty-cycle
inversely proportional to the charger’s current.
d.
Although high ripple current at low frequencies (60Hz/120Hz) is not recommended, the Alliance
Intelligent Battery Series
TM
battery will support average ripple current with peaks up to 240 amps
without any adverse effects. As a comparative example, the maximum ripple current for a typical
AGM (absorbent glass mat) 12 volt 35 Ah VRLA battery (@ 20hr rate) would be 35 Ah/20 hr or 1.75
amps.
