Any charger that has a constant voltage output (rated at 12 VDC or 12/24 VDC) that can apply a charge to one or
more batteries at a time using either alligator clamps or NATO slave connector may be used.
To verify the voltage rating of a charger, attach charger to a fully charged battery (6TMF or VRLA), apply power,
wait a couple minutes until the amp meter registers 1 amp or less, then measure the voltage on the leads at the
battery terminals. Do not exceed 15 VDC if charging one 12 volt battery or 30 VDC if charging a 24 volt battery
Constant current chargers are not recommended for charging Valve Regulated Lead-Acid (VRLA) Absorbed Glass
Mat (AGM) batteries, especially to ensure a complete charge of new batteries.
