Third, Method of recovery Latitude D610 battery PC764
1, first discharge the battery after the victory, the next weld (twist to open) connection lines, and wipe with a clean cloth, which is followed by the opening of the cover, and each battery has a mouth of ventilation, battery venting means are in shelters on edge to see a gap where it is used in the exhaust, the differences of alignment word screwdriver, screwdriver pat, so that screw into the hole, then down upturned point, and then proceeded to drive a Beat (small battery cover the middle of filming because he was in the ventilation openings on both sides, but the battery of the electric motor needs to turn two measures, because it was the opening in the middle, so as not to damage the rubber inside the cap), Alice and many other occasions, the battery cover down can be Alice, do not be too brutal Although ABS material, but still a distortion too much force.
2, after opening the cover, you will find 6 caps (some unscrew the battery), but maybe this time “Leap”, Sheng Liang, flying a rubber cap few, if during the opening the cover does not look like the cover off, slowly eliminated, and hands covered to prevent the rubber cap flying off, because maybe this time the battery internal pressure.

4, after addition of water can be covered with rubber caps and cotton wool, as is the recovery, do a good job can be covered after the cover, but to see the next step.
5 with a small screwdriver lights PVC glue in the lid and battery on a few clicks of the glue, and then you can cover, and the glue does not have much difficulty in avoiding the next opening, but may be too large rubber cap on the flow This tight rubber cap was originally exhaust can exhaust and the battery will explode, and Hehe.
6, install a good battery, put it aside for 10-24 hours and then recharge it, which would position the internal battery of the same electrolyte concentration. Finished charging, the battery capacity would be increased. I wish you good luck! Latitude D820 battery Latitude D830 battery
