How to maintain water battery ,water battery maintenance method

Water - power bottle is a lead - acid battery. Because of the high liquid content in the battery, it is often called a "water and electricity bottle". Water and electricity bottles in the liquid is relatively easy to lose, often refill water, so also called maintainable battery. This kind of battery is used in the automobile motorcycle more, the discharge current is bigger! So also called traction battery, start battery.

Maintenance of the point

Check the liquid level of electrolyte in the battery frequently. Adding electrolyte in time is the most important daily maintenance step. In the process of charge and discharge of battery, water in electrolyte will decrease gradually because of electrolysis and evaporation, resulting in the decrease of electrolyte level. If not timely supplement, it is possible to shorten the service life of the battery, should be timely supplement distilled water, do not use drinking water instead. Because pure water contains a variety of trace elements, the battery will cause adverse effects.

In general, there will be corresponding instructions on the battery cover, which will teach you how to check the liquid level through the observation window. When adding electrolyte, first twist the liquid injection bolt on the battery cover, and then shake the electrolyte well before adding it to the battery. Note that the electrolyte is acidic, which will damage clothing and skin.

In use, also need to pay attention to do not overuse the battery, when the power indicator shows less than 1/3 of the power, please charge in time.

At ordinary times should often check the battery cover, or add liquid on the bolt vent is unobstructed, if there is a plug, the gas produced by the battery work can not go out, the electrolyte will expand and break the battery shell.

The battery will have self-discharge phenomenon, if not used for a long time, the battery power can be easily consumed. Therefore, the battery should be charged once a month.

Hydrating method

1, first take off the battery, remove the cable, and wipe clean with a cloth, and then unscrew the battery vent cover

2. Fill water into the battery with a syringe. After filling water, the liquid level shall not exceed the upper line and shall not be lower than the lower line.

3, add water after the battery vent cover on the screw.

4, pack the battery, load the car can be used, if you need to use the car the next day, you can immediately charge; If you don't have to use the car quickly, wait a night to recharge the battery so that the electrolyte concentration is the same throughout the battery.

Electric vehicle battery maintenance method

1) the electrolyte must be prepared with chemical pure sulfuric acid (or special electrolyte) and distilled water. The electrolyte density generally 1.25 1.29 g/cm3 (15 ° c). Industrial use of sulfuric acid and general water, because contains iron, copper and other impurities, will cause self-discharge and plate damage, can not be used in batteries.

2) the battery has almost no power and the specific gravity of the electrolyte is no less than 1.19. When adding liquid, add distilled water near the lowest scale and then add pure sulfuric acid (or special electrolyte) to make the specific gravity about 1.2 and the amount of liquid added does not exceed the upper limit scale.

3) after injecting electrolyte battery, the battery stand for 3-6 h, stay the electrolyte temperature below 35 ° c to charge.

The charging time is about 3-4h. In the charging process, when the single grid voltage of the battery increases by 2.4v, more bubbles appear in the electrolyte, and then the charging current should be halved. After the end of the charge, to discharge test, so as to avoid the occurrence of vulcanization damage of the battery is only the surface charge, the actual has not been used. So before charging to observe the battery if there is a sulfide precipitation, should be replaced.

4) filled with electrolyte proportion adjustment to: at room temperature for 30 to 40 ° c, the electrolytic liquid to the density of 1.270; 20-30 ° c, the electrolytic liquid to the density of 1.280; Below 20 ° c, the electrolytic liquid to the density of 1.290.
