Motobatt Installation Guide

Which Motobatt Maintainer for Which Size Battery?

Matching a Motobatt Charger and Maintainer with battery capacity is not required, as voltage and amperage are constantly monitored, and reduced or increased by the unique Motobatt 9 stage charging and maintenance process. However you may wish to choose a Motobatt Charger and Maintainer to suit your budget or your performance requirements.

Motobatt models: Little Boy, Water Boy, Fat Boy, Dual Bank and Quad Bank are a microprocessor controlled "Charger and Maintainer" in one unit, and enable a regular consumer without battery knowledge to properly charge and maintain any lead acid battery safely.

Motobatt models: Baby Boy Charger will charge 6 or 12V Power Sports batteries to full charge then move into safe mode and automatically shut off. The Baby Boy Charger is not designed to charge a large dead flat or sulphated battery.
