User Manual
Battery short circuits can generate high instantaneous current and release a great amount of
energy, which may cause equipment damage or personal injury.
If permitted, disconnect the batteries in use before performing any other operations.

1.6.4 Protection Against Flammable Gas



Lead-acid batteries emit flammable gas if they work abnormally. Store lead-acid batteries in a
place with good ventilation, and take fire safety precautions.

1.6.5 Battery Leakage Handling Regulations

High battery temperature may result in battery distortion, damage, and electrolyte overflow.
If the battery temperature is higher than 60° C, check the battery for electrolyte overflow. If
the electrolyte overflows, handle the leakage immediately.
When the electrolyte overflows, absorb and neutralize the electrolyte immediately.
When moving or handling a battery whose electrolyte leaks, note that the leaking electrolyte
may hurt human bodies. Neutralize and absorb the electrolyte with sodium bicarbonate
(NaHCO

1.6.6 Lithium Battery Scenarios

The precautions for lithium battery operations are similar to the precautions for lead-acid
battery operations except that you also need to note the precautions described in this section.
There is a risk of explosion if a battery is replaced with an incorrect model.

Issue 02 (2019-08-30)
Do not use unsealed lead-acid batteries.
Place and secure lead-acid batteries horizontally and ensure that hydrogen discharge
measures are normal to prevent inflammation or device corrosion due to flammable gas
emitted from batteries.
