1. The surface of the battery, cables and bolts should be kept clean and dry all the way. If electrolyte leakage, wipe it by clean cotton yarn, and then rinse by water and then dry it. Note: In the cleaning process, water is strictly prohibited into the batteries to avoid leakage and increased self-discharge, which will result in a operation failure.
2. The battery connection must be good. Always check the battery connections nuts are loose or not, so as to avoid causing a spark or burn pole.
3. Any items are not allowed to be placed on the batteries, in order to avoid short circuit or damage the battery, the negative and positive pole are prohibited to connect directly.
4. The batteries must be charged in the same day after the battery discharged (no matter how long the drive time is and how far the travel mileage is), do not delay charge to the next day, also do not charge more than 24 hours. Otherwise, will shorten the battery life.
5. When the battery discharge, the electrolyte density will increase and the liquid surface op due to the water will electrolyze and evaporate (especially in the summer), so should check regularly and fill electrolyte or distilled water. When close to the full charge state ,the user need to adjust electrolyte density to1.280 ± 0.005 (25 ℃) by filling distilled water or dilute sulfuric acid whose density is 1.400 ,this dilute sulfuric acid is special for lead-acid battery. And the liquid surface should be flat with the highest surface lines. After finish these steps, continue to charge batteries for 0.5-1 hour, so as to make sure the liquid is well-proportioned.
6. Any impurities were not allowed falling into the battery. Water appliances should be kept clean to avoid the impurities into the batteries; 7. If will keep the cart leave unused for a long time, the cart should be stored after the batteries is fully charged, and recharge the batteries every two weeks ,the charging time is around 9 hours.
7. The battery life is generally one to one and a half year , after that period, the battery capacity will be a sharp decline, at this time please replace with new batteries. Must keep the all batteries in one group have the same brand, same capacity, similar voltage (after full charge, the maximum voltage difference should be no more than 0.1V).
1. Keep and use batteries where out of the reach of children.
2. Do not use batteries other than the designated purpose, it may cause battery leakage, heat, or explosion if out of the designated purpose.
3. The battery are prohibited from disassembly, modification, destruction, strong impact or throwing, or may cause battery leakage, heat, explosion.
4. Prevent the batteries from water, fire and heating
5. Battery against short-circuit connections.
6. If the total voltage of batteries over 45V, the insulated gloves and other safety measures should be adopted before the work. Or it may result in a hazard of electric shock.
7. When make maintenance or measurement for batteries, keep a proper angle and distance between the face and batteries , do not allow facing the right top of battery.
8. The plates and separators adsorb sulfuric acid inside the battery, if battery subject to mechanical damage, should prevent the sulfuric acid from contacting skin, clothing and splashing into the eyes; if any above case happen, please wash immediately with plenty of water, or go to the hospital.
9. The work temperature range of the battery is -20~+55 ℃ , if the work temperature is +5~+35℃ , the battery life will be longer.
