The Kisae 40A AC Battery Charger 12V is a brilliant charging solution from Kisae’s “ABSO” line of charges, which features set-and-forget functionality, plus the capacity to charge 3 battery banks simultaneously. Thanks to smart multi-stage battery charging technology, Li-ion, AGM, Gel and FLA deep-cycle batteries are charged precisely to specifications helping maximize battery life. You can even charge different battery chemistries at the same time.
Additionally, this Kisae AC1240 ABSO Charger charges batteries in four primary stages: Bulk, Absorption, Float and Maintenance. As a result, batteries will require equalization less frequently, will get fully charged more quickly, and will have longer lives.
Another great feature is battery bank prioritization function, which makes it possible for the user to designate the highest priority battery to have it charged most quickly, followed by priorities two and three. In the case the user wants all three battery banks charged concurrently, this function can be overriden so that all battery banks are charged at the same rate.
Additionally, the Kisae 40A AC Battery Charger 12V ABSO AC1240 ensures peak battery performance is maintained using its charging algorithm every 7 days. This means that, if you leave home for extended periods, you needn’t worry your batteries will lose charge or degrade, as the charger will top them up weekly according to need. Once the batteries are required again, they’re 100% ready to go!
Finally, Kisae’s ABSO chargers regulate charge output according to the demands of the connected load. During periods when battery discharge rates are high, the Abso charge technology responds by increasing the rate of charge.
