How to distinguish the battery weather to change ?
1,Checking the viewing port. There are currently more than 80% in maintenance-free battery having power viewport. General viewport are in three colors: green, yellow, and black. Green indicates fully charged, yellow represents a slight loss of power, black represents the battery will scrapped soon and need to be replaced. Specifically refer to the label on the battery prompt. View port battery only has the power display purposes.
2, See the voltage. By battery meter to measure battery voltage. Under normal circumstances, the battery no-load voltage is about 13 volts, the voltage at full load is generally not less than 12 volts, the starting voltage is not less than 9.5 volts.When the battery voltage is low, it is difficult to start the vehicle or impossible to start the vehicle.
3, Look at the appearance. First: to observe both sides of the battery whether the situation is more obvious expansion or deformation of the bulge. The second is to observe whether the battery pile head surrounded by some white or green powder similar objects, in fact, that is an oxide battery, good quality or a new battery is generally not prone to these oxides, if the apperance like this, it means that the battery's performance has begun to decline.
