Battery on which we are more familiar with the use of basic passenger cars that ordinary batteries with these two types of maintenance-free batteries. At present, most of the models on the market have adopted a maintenance-free battery, while most Japanese cars, even including Lexus and Infiniti, etc. These high-end Japanese cars are also non-maintenance-free batteries, which is the ordinary batteries. Maintenance-free batteries, as the name suggests the biggest feature is the "maintenance." And ordinary battery consumption is very small compared to its electrolyte, the basic need in life 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 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 car battery electrolyte at each maintenance, if there is a lack of need to add distilled water. But with the upgrade battery manufacturing technology, an ordinary battery maintenance is no longer complicated. Normal use, 2-3 years, all without adding an ordinary battery electrolyte or distilled water. That is what makes a good car battery, car battery for owners, general wholesale, if you do not be a special safeguard ordinary batteries, it can work normally 2-3 years, do not lose the basic maintenance-free battery life up.
