As for checking the starting current is relatively professional point of the car battery, we recommend that you go to repair shop or 4S shop. But under normal circumstances, the starting current does not change with the battery life and reduce the price of the car battery, so as long as the battery voltage can be higher than the cold 12V, to have no significant effect on your car. The three most common habits will hurt a car battery, the next time the car stalled state use electrical equipment which is the majority owner of the car in the most everyday experience, is relatively easy to ignore the problem. For example, sitting in the car and other personal or anything, in order to fuel a lot of motorists will choose to turn off the engine and then sitting in the car listening to the radio or watching DVD with audio, etc. The purpose of doing so is to achieve a fuel-efficient, but it would be deeply hurt your batteries. So this phenomenon is what caused it? To understand why, we must understand the reaction mechanism of charging and discharging a car battery positive and negative plates. Lead oxide battery positive plate is composed of alpha and beta lead oxide, lead oxide composed of alpha lead oxide acts as bones, forming a porous state, strong Dutch energy beta lead oxide, very soft car battery direct participation charge and discharge reactions. Alpha lead oxide in an alkaline environment only generated, while beta lead oxide is produced in acidic lead oxide. Overdischarge when alpha lead oxide positive electrode plate will participate in the discharge reaction of the lead sulfate. After charging, does not generate alpha lead oxide, in an acidic environment Merchants car battery, can only generate beta lead oxide, so that car battery overdischarge of the positive electrode plate which act as multiple skeletal alpha lead oxide will be gradually reduced, leading to the physical damage --- unrecoverable soften the positive plate.
