What are the causes of the battery discharging itself?

A set of battery pack (3) has only 1 or 2 deformations. It means that it may have the following issues:

1, is the battery capacity, charging caused some battery charging lead to deformation. Capacity of reason, there may be short circuit the single, may also be user discharge or self-discharge battery test and so on.

2, is some battery plate irreversible sulfate, internal resistance increases, charging hot deformation.

3, is some cell attachment after charging fever caused by deformation. To check that the discharge capacity and undeformed battery self-discharge performance, without exception, are not of the battery.

The measures

1, ensure no leakage under the premise of as far as possible more fluid, to prolong or avoid "hot out of control".

2, avoid to produce internal short circuit or micro short circuit, and a tendency to micro short circuit.

3, in use process should prevent the occurrence of a discharge, do sufficient electricity storage.

4, strict inspection charger cannot have a serious charge.

Charging at high temperature, it is necessary to guarantee the battery heat dissipation is good. Cooling measures should be taken or shorten the charging time method, otherwise should stop charging. Battery in the case of not working, the phenomenon of electricity consumption gradually accord to discharge itself. Discharge itself cannot avoid completely, it is generally believed the daily consumption itself capacity 1% ~ 2% is normal, if more than this value, for the abnormal discharge itself.

To discharge the reason

1, plate material or impurities in the electrolyte, such impurities and can produce a potential difference between fetter or different impurities, form a closed "local cell" and an electrical current, make the battery discharge.

2, diaphragm rupture results in partial short circuit.

3, or water electrolyte battery cover, make the discharge channel is formed between positive and negative.

4, active material loss, make the plate short-circuit discharge.

5, battery long stored, sulphuric acid in electrolyte sinks and make the upper density is small, lower density, cause to discharge.
