Battery long-term placement without charge. A fully charged battery long-term placement, sulfuric acid will sink lower than the upper large proportion, the lower portion of the plates generates a potential poor, will cause the battery self-discharge. A normal battery fully charged, put a month even without the capacity lost approximately half. If it is insufficiently charged, put a month almost no electricity. So without a fully charged battery, it should be timely to add power.

13, the battery electrolyte is added too much or too little. Add to single-cell battery electrolyte immersion plate should be 10 ~ 15mm, so there is sufficient sulfuric acid to participate in chemical reactions. If it is too easy to spill corrosion around parts; too little, the plate will be exposed, which not only makes the battery capacity is reduced, and the exposed plate will soon be curing.

14, the electrolyte is too thick. Some people think that the electrolyte concentration, participate in multi-ion electrochemical reaction, the battery capacity will be increased. In fact, too strong electrolyte viscosity increases, penetration velocity reduction, resistance increases, so that the battery terminal voltage drops easily decreased. Too thick electrolyte also accelerate the corrosion of the separator and shorten battery life. Therefore, the electrolyte can not be too strong, when electricity sufficient electrolyte specific gravity of 1.28 is appropriate to
