Four pairs of automotive batteries for effective maintenance 4.1 car battery clean the outer surface of the car battery is generally fixed at the bottom of the body, most exposed, over time, the car battery must be covered with a layer of surface dust, even in some circumstances arise oil and electrolyte. If the car is parked or exercising in a wet environment, then the car battery goes into all kinds of oil vapor and surface conductivity, which would lead to increased self-discharge car battery short circuit; in addition there will be a car battery terminal corrosion resulting electrolyte various oxides, resulting in poor electricity, you can use sharp tools and sandpaper removed. So periodically remove surface dirt car battery, car battery can be kept clean and normal power. Car battery surface cleaning work, you can perform the following three aspects: Check the fixing of automotive batteries and various pole wire chuck, there should be no loosening. (2) Check the car battery case should be no cracks and damage to the phenomenon, the pole and wires chuck should be no burning and oxidation. Otherwise the car battery should be removed from the car repair. (3) with a clean cloth to wipe the dust outside the car battery, the electrolyte overflow if the surface can be used cloth to remove dirt or rinse with hot water, and never dry; and remove dirt and oxide column car battery manufacturers, wipe the outside and chuck cable car battery, remove the mounting bracket of the oil, dredge the filler cap vent and clean. When reinstalling, the pole and wires coated with industrial chuck Vaseline or grease (commonly known as "butter"). Check the car battery electrolyte level density 4.4 car battery electrolyte density is with a car battery charging and discharging of different levels and change what makes a good car battery, a drop of electrolyte density is a manifestation of a car battery discharge level. Measuring electrolyte density within each single cell, we can understand the extent of the car battery discharge. When the electrolyte density of less than 1.23 (15 ° C), to deal with a car battery charging. Unscrew each car battery filler cap with a density meter plus liquid from the mouth to suck out the liquid electrolyte hydrometer float float up. When observing the readings, the density should be withdrawn to a position flush with the eye sight, and at the center of the float glass without touching the car battery wholesale and wall, so as not to affect the accuracy of readings. Electrolyte density requirement is as a benchmark for measuring at 15 ° C, if the temperature is below 15 ° C or above 15 ° C, you should use a thermometer to measure the actual temperature of the electrolyte, the electrolyte density calculation for correction value. Note: In the large current discharge after the battery (e.g., start the engine), the density of the electrolyte can not be measured immediately, because the electrolytic solution did not mix well, the density measurement is not accurate. Correcting electrolyte density of the density of electrolyte at different temperatures have some error, the electrolyte needs to be corrected density value contralateral.
