When operating storage batteries, avoid short circuit and overflow or leakage of the
electrolyte.
Electrolyte overflows may damage the device. It will corrode metal parts and circuit
boards, and ultimately damage the device and cause short circuit of circuit boards.
Storage batteries are high-powered and short circuits caused by incorrect operation can
result in serious injury.
Use special insulation tools.
Switch off the power supply during installation and maintenance.
Battery short circuit may cause human injuries. Although the voltage of ordinary
batteries is low, the instantaneous high current caused by the short circuit releases a great
deal of energy.
Avoid battery short circuits caused by metal objects. Do not wear jewelry or watches
when you operate the device. If metal objects must be used, first disconnect the batteries
in use before performing any other operations.
When the temperature of the battery is higher than 60° C (140° F), check the battery for
electrolyte overflow. If the electrolyte overflows, absorb and counteract the electrolyte
immediately.
Take care to protect your eyes when operating the device.
Wear rubber gloves and a protective coat in case of electrolyte overflow.
