h.
Commence charging after the required stand period but no later
than 12 hours after the filling of the first cell.

General Instructions for Sealed Type, Valve Regulated Battery
**************************************************************************
NOTE: Delete paragraph if lead calcium alloy
battery is used.
**************************************************************************
a.
Only authorized personnel who have been familiarized with battery
installation, charging, and maintenance procedures will be
permitted access to the battery room.
b.
At all times while in the battery room, personnel shall wear the
proper safety items as deemed necessary by their task. This shall
include, but not be limited to, face shield, impermeable apron,
and acid resistant boots and gloves. Contractor shall provide one
spare set of safety equipment for Contracting Officer.
c.
These cells are sealed and do not present an acid danger. However
if the container is damaged, exposure to acid could occur.
d.
Sealed batteries will vent potentially explosive gases,
particularly in the event of a charger malfunction. Never bring
any burning material such as lit matches, cigarettes, lighters, or
any type of spark producing material or devices into the battery
room or adjacent to any cell.
e.
Cells connected in series have high voltages that could produce a
shock hazard. Do not ground the DC system. If a ground is placed
at one end of the battery, an increased shock hazard exists
between the opposite end of the battery and ground. Also, if
another ground should develop within the system, it may create a
short circuit which could start a fire.
f.
Ensure that bolted battery connections are torqued to the
recommended values. Loose connections can cause excessive
resistance between cells.
g.
Do not lift cell by its terminal posts as this can damage the
battery. Under no circumstance attempt to remove the pressure
relief valves, vents or vent covers as this will prevent proper
function of the battery.
]3.3.3
Electrical Safety Instructions
a.
Cells connected in series have high voltage potentials that
produce shock hazards.
b.
Discharge static electricity from the body before touching cell
terminal posts by first touching a grounded surface such as the
grounded battery racks.
c.
Only insulated tools shall be used when working on the battery
cells during and after activation charging has begun. Never place
metal tool on the top of cell.
