Some battery rotary exhaust

Some battery rotary exhaust valve base is open, you can not open the exhaust valve and the rotating rubber exhaust valve to open the base. Some cells there are some rubber around the filler cap. Open the lid, with shining flashlight to see whether there are dry holes within the phenomenon, namely, whether the battery is dehydration. The battery plate is wrapped in a white glass-fiber cotton, the normal situation should be moist. Inhalation of distilled water with the dropper from the vent into the cell. To add a battery good water blocking material covered with breathable vent to prevent dust from falling into the vent. Best to use medical secondary distilled water. Replenishment of the principle is not to rather more than less. You can not add more acid, causing a decreased proportion of battery capacity will be insufficient. No experience, can master 5mL per hole. Is best looked at Canada, damp, shiny, watery. Just damp, shiny, the more, and watery on too much.
Special Note: replenishment tool for the use of glass, plastic straws. Recommend the use of medical disposable syringes, easy to use and convenient measurement. Replenishment tools do not use any metallic utensils, syringes, needles should be pulling out of metal, set of a plastic tube for later use.
3. Sulfate
Battery discharge, the cathode has produced in the cathode lead sulphate, anode oxidation due to oxygen very presence of sulfuric acid is extremely easy for charging lead into lead dioxide, while the cathode is different, save in the long term power loss, often over-discharge, long-term charging less than the presence of other factors will be gradually formed on the surface layer of dense negative hard lead sulfate layer, not only in itself a significant decline in solubility, it is difficult to participate in response, while blocking the electrolyte active material contacts and deep channel, resulting in the battery capacity decline.
Repair Methods: Pulse sulfide battery repair instrument repair, using high-voltage (30V-50V) pulse (8330HZ) small current (battery nominal capacity of 1% -2%) of the way, with 10-20 hours of time to In addition to change the battery inside a hard crystallized lead sulfate. IBM 92P1089 battery

4. Plate softening
Plate is a multi-gap material, there is large area than the plate itself, the more surface area, the battery charge-discharge cycle repeated, with the very board alternating transformation of different materials will make a gradual rate of plate space decline in performance on the appearance, it is positive plate when the surface of a solid from the beginning a gradual change until it becomes soft and mushy, then declined because of the surface area would lead to a decline in battery capacity. High-current charge-discharge, over-discharge would accelerate the softening of the plate.
Repair Methods: 10.5V battery discharge only after the deep discharge 1-5 hours with the light bulb. Then use the activation device, activation of repair.
