4.6.3.3 Use of battery
(1) Before use of battery, dust and dirt should be removed from the appearance, and check should be made
piece by piece for any damage. If there is any damage, it can be repaired or replaced as the case may be.
(2) Preparations before charge:
(a) Check the charge equipment, instrument and tools. If there is any shortage or fault, it should be timely
prepared or repaired.
(b) The capacity and voltage of charge equipment must match with those of the battery.
(c) The DC power supply should be used for charge. The positive ( + ) and negative (-) of charge device
are respectively connected to the positive ( + ) of battery pack
The pole and pole connection (I) allows absolutely no wrong connection to prevent the damage on the
battery.
(d) In charge, the temperature of electrolyte solution is controlled between 15~45°C.
(3) Maintenance and precautions of battery
(a) The surface of battery should be kept clean and dry.
(b) When the discharge begins and the density of electrolyte solution (30°C) failed to reach
1.28±0.01g/cm3, the adjustment should be made.
Adjustment method：
When the density is low, a part of electrolyte solution should be taken to pour the sulfuric acid solution in pre-
prepared density not more than 1.400g/cm3. If the density is high, a part of electrolyte solution can be taken to
pour the distilled water for adjustment.
(c) The level of electrolyte solution should be 15～20mm higher than the grid guard.
(d) After the discharge of battery, the charge should be given in time. The delay time cannot be more than
24h.
(e) For the battery, the overcharge, over-discharge and insufficient charge should be avoided, otherwise,
they will shorten the service life of battery.
