1. Keep the surface of the battery clean. Wipe the outside of the battery with a rag and pour the water. Wipe off the dirt, oil, white powder, etc. on the panel and the stigma (that is, the positive and negative poles). During the cleaning process, tap water is strictly prohibited from entering the battery to avoid leakage and increase self-discharge, resulting in malfunction of the vehicle; often scrubbing the stigma of the battery, not only the white acid powder will not accumulate on it, but also help to improve the battery. Service life.
2. Always check whether the small holes on the battery cover are unblocked when driving daily. If the small hole of the battery cover is blocked, the generated hydrogen and oxygen will not be discharged. When the electrolyte expands, the battery case will be broken. When the internal air pressure is too high, the battery case will be broken and the battery life will be affected.
3. Check the connection problem of the battery cable regularly to check whether the cable is loose or not. The cable terminal connection should be tight and reliable. Avoid false connections and sparks, and damage the poles (do not switch the battery on or off when the power lock is turned on).
4. Check the internal electrolyte level of the battery. The liquid level of the electrolyte should be 10-15 mm above the plate. If the electrolyte is found to be too low, add distilled water or a special lead-acid battery replenisher. Never use pure water instead. During the use of the sightseeing car battery, due to the electrolysis and evaporation of water in the electrolyte, the density will increase and the liquid level will drop (especially in summer). Therefore, it should be checked frequently and filled with electrolyte or distilled water. At the end of the charging period, the battery should be adjusted to a density of 1.280±0.005 (25°C) with distilled water or dilute sulfuric acid for lead-acid batteries with a density of 1.400. The liquid level should be level with the highest liquid level. Continue to charge for 0.5-1 hours after adjustment to make the inside uniform.
5. Do not let other impurities fall into the battery when adding liquid. If impurities fall into it, do not use metal materials to fish. Use dry wood rods to remove impurities. If you use iron wire or copper wire to hook, metal molecules will be in Entering the battery under the corrosion of sulfuric acid causes self-discharge and damages the battery.
6. If the battery is not used for a long time, it will slowly discharge itself until it is scrapped. Therefore, when the sightseeing car is not used for a long time, the battery is charged and maintained once every other month. After the battery is discharged (regardless of the vehicle's travel time and mileage), it must be charged on the same day. It is not allowed to charge the next day or charge for more than 24 hours, otherwise the battery life will be affected.
7. When charging the battery, place the sightseeing car in a well-ventilated position, open the battery cover, and let the generated gas overflow from the battery end cover to avoid internal gas accumulation and sound explosion. (Be sure to turn off the sightseeing car when charging. power supply).
8. If the vehicle is not used for a long time, the battery should be fully charged and stored, and it should be charged once every half month. The charging time is about 8 hours.
9. The service life of the battery is generally one to one and a half years. At that time, the capacity of the battery will drop sharply. At this time, the new battery must be replaced, and the same brand, same capacity and voltage should be used as much as possible.
