There may be two reasons for the bulge of lithium polymer battery. One is the manufacturing level of lithium polymer battery, the electrode coating is not uniform, and the production process is rough. The second is the problem of over charge and over discharge in the use process. These two factors will lead to the polymer lithium battery in the use of the process, the polymer lithium battery inside the violent reaction similar to short circuit, generate a lot of heat, which leads to the decomposition of electrolyte gasification, polymer lithium battery bulging up.

If you have more than one lithium-polymer battery, it should be that the cutoff voltage of the charger you are using does not match the lithium-polymer battery. It is recommended to replace it.

In addition, the polymer lithium battery for a long time will not be bulging phenomenon, because the air is conductive to a certain extent, therefore, put too long time is equivalent to the positive and negative electrode of the polymer lithium battery direct contact, a chronic short circuit.

Spare polymer lithium battery if not used for a long time, it is recommended not to charge full electricity to save, it is best to retain about 60% of the power - in addition, after a period of time to take out to use, this will be good for the life of lithium polymer lithium battery. Note that the polymer lithium battery charger drum can not be used, replace a new polymer lithium battery as soon as possible.
