Maintenance-free batteries, as the name suggests the biggest feature is the "maintenance." And ordinary battery electrolyte consumption than its very small 12v car battery during the life of the basic need add distilled water. It also has a shock, temperature, small size, low self-discharge characteristics. Of course relative, its price will be more expensive than ordinary batteries. As for life, under normal circumstances, maintenance-free battery replacement cycle suggestion about 3 years, and quite ordinary batteries. How to battery maintenance: Maintenance properly, ordinary battery life of more than ordinary batteries maintenance-free batteries the most obvious feature is its top six can unscrew the plastic closures, as well as the vent above. These closures are used for filling, check the electrolyte and gas emissions purposes. According to theory, ordinary batteries need to check the height of the electrolyte at each maintenance, if there is a lack of need to add distilled water. But with the battery manufacturing technology upgrades automotive batteries, battery maintenance is no longer an ordinary complex. Normal use, 2-3 years, all without adding an ordinary battery electrolyte or distilled water. In other words, for the average car owners, if you're not an ordinary battery to special maintenance, it can work normally 2-3 years, maintenance-free battery life does not lose the basic. Maintenance-free batteries, although called "maintenance-free", but not completely laissez-faire attitude. Manufacturers recommend checking once every 30,000 kilometers batteries once every 80,000 km maintenance. But now capable of operating overwhelmed 4S shop or repair factory few and relatively maintenance-free battery life is fixed, under normal use, 2-3 years must also be replaced, and nothing can extend its the life of the road. From the perspective of the use and maintenance, whether your car is filled with ordinary batteries or maintenance-free battery car battery production, normal life in about 2-3 years, and during that time the basic needs of your "extra care" . As would like to extend the life of ordinary batteries can be used about three years after adding the electrolyte, thus extending the life of 1-2 years, as maintenance-free batteries do, or directly for it, basically did not have to repair a car battery to join, car batteries, car batteries Wei Lai Po provided by Shenzhen Wei Lai Po Battery Limited.
