THEORY OF OPERATION
Valve Regulated Lead-Acid (VRLA) and Absorbed Glass Mat (AGM) batteries have proven to be rechargeable
multiple timesfrom voltagesaslow as0.24 VDC. Therefore, the battery must be charged and tested before disposal
is approved. It is a sealed system with Absorbed Glass Mat (AGM) technology that contains an absorbed amount
of electrolyte in the cell chamber; therefore NO liquid will be introduced into the cell chamber at any time after
manufacturing. Other than removal of dust, dirt or corrosion buildup on the exterior of the battery no maintenance
beyond recharging is required.
This battery contains sulfuric acid electrolyte so proper care and considerations should be
taken to protect equipment and personal clothing when handling batteries with damaged or
broken cases. Use approved, acid resistant protective clothing and wash and neutralize
battery box after removal of damaged battery pieces.Failureto do so may result in personnel
injury or death.
Recharge and Disposal Directive
When the user's organization does not have the capability to recharge the VRLA battery it should be directed to the
supporting sustainment unit to have the battery recharged and returned to service. Field level maintenance is not
authorized to turn in this battery for disposal (unless physically damaged) but, due to the cost and rechargability of
this battery, it should be disposed of only after testing and attempting to recharge it without success. If eld level
maintenance is unable to test or recover the battery, turn into sustainment level for testing and recharging.
Only sustainment level may dispose of VRLA batteries deemed un-rechargeable.
