(1) and method of use
1. Battery red for positive, black for negative, please correct connection.
2. The battery is charged, the user can directly use, such as the factory for a long time, should be added before use electricity;
3. The battery installation and wiring connections shall be conducted by professionals.
(2), maintenance and matters needing attention
1, the battery should be at room temperature, stored in a dry, clean and well-ventilated environment, avoid direct sunlight, away from heat source;
2, keep the external battery and wiring in clean, dry;
3, recommended to recharge the battery at room temperature environment, winter insulation antifreezing measures should be taken;
4, keep clear of battery side hole;
6, electrolyte to skin, eyes, clothes, etc all have corrosion effect, attention should be paid to the prevention of electrolyte overflow.
(3), a common problem:
1, the discharge: due to the user equipment without low voltage protection, ensure the battery is not lower than 10 v electricity;
2, charge against: if serious reverse charge, low voltage will charge more and more, try to avoid;
3, battery short circuit: battery short circuit will cause damage, even summon up until discarded;
4, the batteries voltage: the battery has been damaged, stop using;
5, battery summon: internal plate circuit directly discarded stop using;
6, liquid overflow: there are other liquid should be wiped clean to avoid corrosion metal objects, have a small amount of overflow does not affect the use;
7, transport and crack: cause and crack should immediately stop using it.
