As one of the core components of electric bicycle, the service life of battery largely determines the service life of electric bicycle. Therefore, strengthening the maintenance of the battery will prolong the service life of the battery. For the maintenance of lead-acid batteries, here are some tips.

1. Charging

Lead acid batteries have no memory. The main reasons for the rapid reduction of capacity are battery vulcanization, water loss, power loss and other reasons. The most feared reason for batteries is "power loss" and undervoltage. Batteries often "power loss", and battery plates are very vulnerable to injury. In reality, up to 70% of the battery capacity of electric vehicles is reduced, and the electrode plates are pulled by the strong current (starting current) during discharge (especially for electric motorcycles), The electrode plate strain belongs to the physical damage of the battery, which cannot be repaired. Therefore, it is necessary to "use cars and charge batteries every day" to ensure that the battery has sufficient voltage at any time.

2. Make up distilled water regularly

Users generally believe that maintenance free batteries do not need to add water. In fact, this statement is wrong. The maintenance free battery will generate heat during charging and high current discharge. If there is heat, there will be water evaporation. Although the process of water evaporation is very slow, the cumulative amount of water evaporation cannot be underestimated over time. Therefore, the battery should be hydrated every 6 months or so, so that the service life of the battery can be extended.

3. Electric vehicle start

The starting current of electric vehicles is very large, especially that of high-power motors. High current will hurt the battery plate. The best way is to start the electric vehicle after riding like a bicycle before starting.

4. Battery discharge

After the battery has been used for a period of time, some active substances will inevitably sink. If the active substances are not activated in time, it is bound to have some impact on the capacity of the battery. Therefore, when electric vehicles are often used, the battery should be deeply discharged once a quarter.

5. Charger

The charging process of a new battery usually takes 6-8 hours. The charger will light up after it is fully charged. If the charging time is too long, check whether the charger voltage protection device is damaged. If it is damaged, it is necessary to replace the charger in time, otherwise it is very easy to charge the battery. In addition, do not buy a fast charger. Fast charging also damages the battery plate.

6. Not used for a long time

The purpose of this is to prevent the storage battery from vulcanization and "power loss" due to long storage time.

7. Prevent the battery from being exposed to the sun

Exposure to the sun will raise the temperature of the battery and greatly shorten the service time of the battery.

8. Battery protector

The battery protector, also known as the pulse generator, continuously eliminates the battery vulcanization due to the pulse, so that the electrode plate is always "clean", so as to prolong the service life of the battery, but has little effect on the battery electrode plate damaged by large current.

9. Cleaning

If the battery is not cleaned in time, it is easy to affect the service life and power on effect of the battery. In short, battery is an electrochemical device that can convert chemical energy into electrical energy. It is essential to keep the battery in normal operation. Oxidation reaction is easy to occur between the pole of the battery and the collet, and even the metal parts of the collet can be rotted seriously.

For ordinary lead-acid batteries, special attention should be paid to the usual cleaning work. Pay attention to check whether the pole and collet are firmly connected, whether there is any corrosion and burning, and whether the exhaust hole is blocked and whether the electrolyte is reduced. If any problem is found, it should be handled in time. When starting the vehicle, each start time shall not exceed 3 to 5 seconds, and the restart interval shall not be less than 10 seconds. If the car is not used for a long time, it should be fully charged first. At the same time, start the car every other month and keep it running at medium speed for about 20 minutes. Otherwise, it will be difficult to start if it is placed for too long. General maintenance free batteries should also be checked frequently for working conditions and replaced in time in case of problems.

The maintenance free battery has been put into use in most cars. This kind of battery does not need to add distilled water in use, the terminal posts will not corrode, the self discharge is less, and the service life is long. However, if the battery is not checked in time, the owner of the battery is still unclear when it is scrapped, which will also affect the normal operation of the vehicle.
