Batteries in use arising from breakdown, because of maintenance and many are caused by improper use. External battery failure, have the shell and crack the lid, sealing glue dry, very loose and corroded piles, etc.; internal fault has plate vulcanizing, self-discharge, the internal short circuit, active material shedding, such as plate hog.
In use, mainly to prevent excessive discharge and excessive charging. Excessive discharge plate sulfide will very on-board active substances should not take part in the formation of a chemical reaction PbSO4 white crystals, hp laptop battery .
This is one of the reasons for the early damage; at the same time because of high current caused by excessive discharge, such as excessive use of starter , high-current discharge time is too long, and should not be replenished in a timely manner charge, resulting in plate hog, damaged partition, so that the omnibook xe battery in a bad state. Excessive charging, the power of water electrolysis to produce hydrogen and oxygen, so that plates have a certain pore pressure plate active material and irreparable loss.
