Wear electric cost how to do? Lead-acid batteries and bearing inspection without! ! ! How to do?

Check the battery is a match of expensive cost, use undeserved, battery present range greatly shorten problem in less than a year. So it is necessary to check time sex, is the most intuitive to watch battery appearance, look for any signs of present obvious poles have saline or batteries. The traditional way to check the battery are: burning water, turn on the light electricity method, capacitance method, power consumption but detection accuracy is not ideal. Dedicated detector to understand power, voltage, etc. , all kinds of data values. The traditional detection. Total joint link battery, electric fuse beginning power consumption. Using the multimeter, quantity of each battery voltage. If the battery maximum and minimum voltage data is 0. 5V。 To clarify the minimum data values of battery capacity and other groups of battery capacity is not online. If in use, several other batteries will damage. Instrument detection. Instrument detection can understand each section of the battery discharge voltage and time, because the instrument is directly connect each section of the battery to stop testing. The same is in power, maximum and minimum difference of 0. 5 v, clarify the battery capacity. Bearing inspection bearing is a wear-resistant parts. The price cheap, good applicability, etc. But lack of oil or water bearing, rust will accelerate bearing damage. Set up the car, dangling the wheels, the wheels turn smooth silent, clarify the bearing is good. If the wheels, present a muffled voice, turn the wheels fixed several times to stop down, clarify the bearing have rust damage. The front and back of the check method. You should be careful to change the rear wheel bearing to match, motor cover to avoid knock off to broken motor bearing cover.
