Precautions for batteries

Oct 17,2022

Before installation, check whether the battery is damaged or leaking, and clean the surface of the battery with a dry cloth. If the shell of the battery is cracked or leaking, replace the battery immediately to avoid acid corrosion. The batteries shall be installed upright and not upside down. The spacing between adjacent batteries shall be more than 2mm. The batteries shall be anti-vibration and anti-pressure. The batteries shall be installed firmly. During use, the batteries shall not move, impact, rub against each other and water shall not enter the batteries. To ensure safe use, the battery box where the battery is installed must be provided with a vent hole of not less than 8mm, and it must not be blocked to prevent the gas generated by the battery from accumulating in the battery box. The batteries shall be connected in series, and the positive and negative polarities shall be correct, and the connection points shall be in good contact, and no spark should be generated. Electric locks, safety seats and other devices that are prone to spark should be isolated from the battery. The battery is charged before leaving the factory. Usually, users can load it directly. If it is put on hold for a long time (more than 2 months), it should be recharged before use: Plug the charger into the battery box and then connect it with 220V AC. After the charger turns green and continues charging for 1 ~ 2 hours, you can stop charging. When an electric vehicle is running, it's best to charge it after the battery has used up about 80% of its power, not after the battery is exhausted. If the battery is exhausted, the power supply should be turned off, and the battery's 'recovery voltage' should not be used to force it to run, so as to prevent the battery life from being shortened due to 'over-discharge'. (The minimum battery protection voltage of 36-volt electric moped is 31.5 volts, and that of 48-volt electric moped is 42 volts) The charger used with the vehicle should match the battery pack and meet the requirements of the charger parameter table in this instruction, otherwise it will damage the performance of the battery. The battery should be fully charged after the electric car is not used for a long time, and it is strictly forbidden to store it in a deficit state for a long time. If the continuous charging time of the battery exceeds 10 hours, the charger still does not change the lamp or the battery is hot, it should immediately stop charging and hand it over to the battery after-sales service. It is strictly forbidden to continue charging without changing the lamp. Batteries of different models, brands, old and new cannot be mixed. Keep batteries away from the fire source and heat source. It is strictly forbidden to be exposed to the sun in hot season. The battery should avoid violent vibration, collision and short circuit between positive and negative electrodes. The capacity of the battery is based on the ambient temperature of 25℃. When the temperature drops by 1℃, the capacity of the battery drops by about 1%. The influencing factors of the ambient temperature should be considered in use. The battery should be used in the low temperature environment below -10℃ as far as possible. Battery is a consumable. After a period of charge and discharge cycle, the battery capacity will gradually decrease, resulting in a decrease in the mileage of electric vehicles, which is a normal phenomenon. However, if the battery capacity drops below 60% of the standard value within the warranty period, it will be regarded as battery failure. Please contact us in time. After the warranty period expires, although the battery capacity drops below 60% of the standard value, it is a normal loss and does not belong to the warranty scope. If the battery is used beyond the warranty period, it should be handed over to the professional maintenance personnel of our company for a comprehensive inspection, and it can only be used after confirming that there are no potential safety hazards. The electrolyte in the battery is highly corrosive acid, so don't splash it on the skin or clothes. If it does, wash it with plenty of water immediately, and send it to the hospital for treatment in severe cases. 18. Please hand over the scrapped batteries to the recycling station (merchant) for unified treatment, and do not discard them at will.

1.安装前应检查蓄电池是否破损漏液，并用干布清洁电池表面，如发现蓄电池外壳破裂、渗漏时，应立即更换蓄电池，以免造成酸液腐蚀。

2.电池应正立安装，不得倒置，相邻电池之间间距大于2毫米，同时要防振、防压，安装牢固，使用过程中不会窜动撞击、相互摩擦，不能进水。

3.为保证安全使用，安装电池的电池箱必须留有不小于8毫米通气的通气孔，且不得堵塞,防止蓄电池产生的气体聚集在电池箱内。

4.各蓄电池串联连接，正、负极性应正确，并保证连接点接触良好，不得产生火花。

5.电门锁、保险座等容易产生电火花的器件应与电池隔离。

6.电池荷电出厂，通常用户可直接装车使用，如搁置时间较长(超过2个月)使用前应补充充电：将充电器插上电池箱后再接上220伏的交流电，充电器转绿灯后继续充电1～2小时，就可停止充电。

7.电动车在运行时，最好在电池使用了80%左右的电量后进行充电，不要在电池电量用尽后再充电，如果电池电量一但用尽后，应关闭电源，不要使用电池‘回升电压’来强制行驶，以防止因‘过放电’而缩短电池寿命。(36伏电动助力车最低电池保护电压为31.5伏,48伏电动助力车为42伏)

8.随车使用的充电器应与电池组相匹配，符合本说明充电器参数表要求，否则将有损蓄电池性能。

9.电动车因长期不用需对电池充足电后再进行搁置，严禁在亏电状态下,长期搁置存放。

10.蓄电池连续充电时间超过10小时, 充电器仍不转换变灯或出现电池发烫现象,应立即停止充电交由电池售后服务处理,严禁在充电器不转换变灯的情况下继续充电。

11.不同型号、不同品牌、新旧不一的电池不能混用。

12.蓄电池不可靠近火源、热源，炎热季节严禁在阳光下直接暴晒，应避免蓄电池剧烈震动、碰撞和正负极短路。
