If you are unsure of the output voltage of your charger test it first, see (WP 0005). If charger
is an older version and has no adjustments it most likely is not compatible with Absorbed
Glass Mat (AGM) Batteries. Closely monitor its usage to ensure it does not damage the
batteries being charged.
· When charging multiple batteries in one set they must be identical types. Do not charge
a flooded battery and a VRLA battery on same charger at the same time.
· Do not mix flooded and VRLA batteries in the vehicle. VRLA batteries should be from
· Be sure to charge batteries in well ventilated areas only.
· During charge cycle, the batteries should be examined daily.
· Voltage levels stated in this Technical Bulletin should not be used to set the vehicle
voltage regulator, refer to the appropriate vehicular Technical Manual for this value.
· VRLA-AGM batteries are lead-acid batteries and must be disposed of following local
procedures for the recycling of hazardous waste materiel. Do not dispose of by putting
After performing the pre-charge inspection and testing, the Valve Regulated Lead-Acid (VRLA) battery can
be charged either in or out of the vehicle by attaching charger leads directly on the battery (12 VDC) red lead
to positive post (+), black lead to negative post (-) or through the vehicle's NATO slave connection, (24 VDC).
Batteries can be charged individually or as a group using the following procedures. If using the NATO slave
receptacle use a charger with 24 volt capacity and a NATO slave connector plug.
If charging on the vehicle make sure all current draws (i.e. lights, electronic equipment etc.) are turned
OFF. Do not attempt to jump start the vehicle with the charger unless it is specifically designed to do so;
i.e. includes power assist mode.
