Water batteries are a type of lead-acid battery. Because the liquid content in the battery is high, it is often called "water battery". The liquid in the water battery is relatively easy to lose, and it is necessary to replenish water frequently, so it is also called a maintainable battery. This kind of battery is mostly used in automobile and motorcycle, and the discharge current is relatively large! So also called the traction battery, start the battery.
Maintenance pointsAlways check the liquid level of the electrolyte in the battery. Adding the electrolyte in time is the most important routine maintenance procedure. During the charging and discharging process of the battery, the water in the electrolyte is gradually reduced due to electrolysis and evaporation, resulting in a decrease in the electrolyte surface. If it is not replenished in time, it is possible to shorten the service life of the battery. The distilled water should be replenished in time, and it should not be replaced with pure drinking water. Because pure water contains a variety of trace elements, it will have an adverse effect on the battery.
There will be corresponding instructions on the battery cover to teach you how to check the liquid level through the observation window. When adding the electrolyte, first unscrew the liquid injection bolt on the battery cover, then shake the electrolyte and add it to the battery. Note that the electrolyte is acidic and will damage the clothes and skin.
In use, you should also pay attention not to overuse the battery. When the battery indicator shows that the battery is less than 1/3, please charge it in time.
Always check the battery cover frequently, or whether the vent hole on the filling screw is unobstructed. If there is a blockage, the gas generated during the operation of the battery will not be discharged, and the electrolyte will expand and break the outer casing of the battery.
The battery will self-discharge, and if it is not used for a long time, the battery can easily consume light. Therefore, the battery should be charged once a month.
1. First remove the battery, remove the cable, wipe it with a rag, and then unscrew the battery vent cover.
2. Use a syringe to replenish the battery. After the water is replenished, the liquid level must not exceed the upper marking line and cannot be lower than the lower marking line.
3. After adding water, screw the battery outlet cover.
4, install the battery, you can use the car, if you want to use the car the next day, you can also charge immediately; if you do not use the car, then wait a night to recharge, this can make the battery inside the various positions The electrolyte concentration is the same.
Electric vehicle water battery maintenance method1) The electrolyte must be prepared from chemically pure sulfuric acid (or special electrolyte) and distilled water. The electrolyte density is generally from 1.25 to 1.29 g/cm3 (at 15 ° C). Industrial sulfuric acid and general water, due to impurities such as iron and copper, cause self-discharge and damage to the plates, and cannot be used in batteries.
2) The battery has almost no electricity, and the specific gravity of the electrolyte is not less than 1.19. When adding liquid, the distilled water is added to the vicinity of the lowest scale line, and then pure sulfuric acid (or special electrolyte) is added to make the specific gravity 1.2 or so. Exceeded the upper limit.
3) After the electrolyte is injected into the battery, the battery is allowed to stand for 3-6 hours, and the electrolyte temperature is lower than 35 °c to be charged.
Charging time is about 3-4h. During the charging process, when the battery cell voltage rises by 2.4v, more bubbles appear in the electrolyte, and the charging current should be halved. After the end of charging, a discharge test is to be carried out to prevent the battery from being damaged by vulcanization only to be surface-charged, which is practically unusable. Therefore, before charging, observe that the battery should be replaced if there is sulfide condensation.
4) When the filling is full, the specific gravity of the electrolyte is adjusted to: when the room temperature is 30-40 °c, the relative density of the electrolyte is 1.270; when the temperature is 20-30 °c, the relative density of the electrolyte is 1.280; when the temperature is below 20 °c, the relative density of the electrolyte It is 1.290.
