There are five steps to add water to the lead-acid battery:First prepare materials. Electrolytic solutions were configured with distilled water and glue acid, and 0.5 ml of pure sulfuric acid was added 500 mL of distilled water. Prepare the standard rubber exhaust valve spare. The required tools have a punctive straw (instead of the disposable needle tube) transparent polyethylene tube (which is suitable for the suction of the straw or needle tube) ABS glue.
Then open the cover plate over the lead-acid battery along the exhaust hole. Some lead-acid batteries of the lead-acid batteries are bonded with ABS glue, and some lead-acid batteries are connected with a buckle, pay attention to the cover, do not damage the cover. At this time, you can see the rubber-cutting breath of the six exhaust valves.
The rubber is opened, and the exhaust hole is exposed, and the inside of the lead-acid battery can be seen by the exhaust hole. Some lead-acid battery exhaust valves can be centered, and some lead-acid batteries have some fillers around the rubber, pay attention to the filler.
The configuration in which the contained electrolyte is drawn and injected from the exhaust hole. The electrolyte is to cover the polar plate 1 mm.
Finally, the exhaust hole of the lead-acid battery of the filled electrolyte is covered with a gas permeable shield to prevent dust into the exhaust hole. Still 24h, observing whether there is a flowing electrolyte (free acid) inside the exhaust hole. If not, it is necessary to supplement the electrolyte.
Then, the battery is completed.
