Battery capacity: 1, the battery capacity is under the specified conditions for car battery discharge, fully charged battery can emit electricity, with "C" indicates. 2, the battery capacity is a sign of external battery discharge capacity, a measure of the quality of the merits of the battery and the choice of the most important indicators of the battery. 3, the battery capacity using Ah (ampere hour) to measure. That capacity is equal to the discharge current and discharge duration of the product. Battery Troubles and an external fault: shell cracks, corrosion pole, pole loose, sealed plastic dry. 2, the internal fault: plate curing, the active material shedding, plate gate frame corrosion, plate short circuit, self-discharge, plate doming. What factors will affect the life of the battery?
