For battery maintenance, maintain a certain level of electrolyte liquid level as required. After measurement, put the electrolyte back into the glass tube. If the liquid level is not enough, add distilled water in time. Never add spring water, river water, or tap water. Do not add dilute sulfuric acid, otherwise it will increase the electrolyte density and damage the plates. It should also be noted that distilled water should be added when the battery is in a charged state to ensure that the electrolyte is mixed more uniformly; the liquid level should not be too high to prevent the electrolyte from overflowing during charging and discharging.
Remove the yellow-white paste on the battery cover in a timely manner. The yellow-white paste on the battery cover is due to the sulfuric acid solution splashing around the battery cover and the pole pile, which results in electrochemical corrosion at the electrode pile.
The white substance is lead sulfate and the yellow substance is ferric sulfate, which is very corrosive and has a large resistance. If it is in the contact of the wire, a large contact resistance will be formed, resulting in poor conductivity.
For this reason, it is necessary to frequently use alkaline water, and also use 10% soda water or 10% ammonia solution soaked cotton yarn to wipe off the electrolyte splashed at the battery case and cover, so that the surface is often neutral. If there is oxide in the gap between the pole and the wire joint, it can be scraped off with a tool.
Regular supplementary charging Under normal circumstances, the discharged battery should be charged within 24h; for the battery on the stopped machine (or large equipment that is not in use), it must be recharged once a month; the battery in use, It should be removed every two months for a supplementary charge.
Periodically check the density of the electrolyte The electrolyte density must be adapted to the region and season. According to practical experience, the relative density of the newly charged battery electrolyte can reach the relative density of the newly charged battery electrolyte before and after summer in most parts of China. The relative density of the electrolyte should be maintained at 1.15 ~ 1.18g / m3. The relative density of the electrolyte in autumn should be gradually increased from 1.18g / cubic meter to 1.25g / cubic meter, adjusted to 1.285g / cubic meter in winter, and distilled water was gradually added during the Spring Festival to lower the relative density.
