• Before performing any work operation, follow proper ESD
protection procedures to discharge the static electricity from
your body.
• Never tamper with or block the vent caps of batteries.
Damaged or clogged vent caps may result in an explosion
due to excessive internal pressure. Such an explosion could
short circuit other battery modules, result in a fire, injure
personnel, or cause damage to equipment.
• Never charge a battery that is visibly damaged or frozen
(typically at temperatures less than -40°C or -40°F).
• Be alert to procedures that may create potential hazards,
such as creating sparks next to the batteries. Some
examples:
– Avoid disconnecting the circuit at the battery terminals
while the battery is being discharged or charged.
– Avoid making connections at the battery terminal with
the other end connected to a load or charging system
(unless the circuit has been verified to be open).
– If there are no devices for opening the circuit before
disconnecting or connecting the battery, here are some
suggested procedures:
• Make sure the free end of any wire connected to the
batteries is insulated until it is ready to be connected
to the load or charger or immediately after being
disconnected from the load or charger.
• Connect to the battery terminals first before
connecting to the load or charging system.
• Disconnect at the load or charger first before
disconnecting at the battery terminals.
Freshly charged batteries may produce explosive gas.
• Avoid handling a freshly charged battery within 24 hours
after removing the charge. If it must be handled, use
extreme caution and avoid any sparks or touching the
battery in the area of the vents.
