CHARGING PROCEDURES INTRODUCTION
This work package covers general instructions for all charging procedures. For detailed information about different
charging configurations see (WP 0007, 0008, and 0009).
· Perform all charging functions in a ventilated area. The potential for hydrogen gas build
up and explosion exists with any lead-acid battery. Do not smoke or have open flames
in the charging area. Failure to comply may result in personnel injury or death.
· Immediately stop charging any battery that develops signs of melting or swelling or if
the surface temperature of the case is too hot to comfortably touch with a bare hand.
Do not handle or attempt to move battery until it has cooled for a couple hours to avoid
the risk of an explosion. Failure to comply may result in personnel injury or death.
· Many of these batteries weigh over 80 pounds and a two-man lift is required. Battery
should be carried by the handles supplied and should not be lifted by a battery strap
attached to the posts. Failure to carry a battery in this manner may lead to personnel
injury or damage to the battery.
· All charging functions should be performed in a ventilated area. The volume of hydrogen
gas emitted from the VRLA battery is far less than can be expected from the 6TMF
flooded lead acid battery. The technology used in the VRLA battery greatly reduces the
risk of explosion, however, the potential for hydrogen gas exploding exists with any lead-
· Monitor the battery for excessive heat during charging. During the charging procedure,
some heat is generated as a natural result of charging. However, if a battery becomes
too hot to comfortably touch with the bare hand or the case or lid begins to melt or shows
signs of swelling, it should be removed from the charger immediately. Allow battery to
cool before attempting to move. If this condition exists repeatedly with a specific charger,
the charger may not be compatible for use with VRLA battery technology and its use
should be discontinued.
