4.2 car battery fluid level checks unscrew the filler cap, with a 6 to 8 mm inner diameter, about 150 mm vertical glass tube is inserted into the liquid inlet, the contact plates edge up, then use your thumb pressed glass tube catchy, with the index finger and ring finger grip the glass, gently put, glass is the height of the electrolyte within the car battery electrolyte height above the plane of the plate should be 10 to 15 mm is appropriate. Checked, then the final electrolyte into the original single-cell batteries. 4.3 car battery electrolyte supplement inspection if the car battery electrolyte level is too low, add distilled water should be on the market or car battery car battery replenisher What makes a good, if not allowed to add tap water, river water, well water, etc. The water does not meet the requirements of wholesale car battery, to avoid entering the impurities, resulting in the discharge of their own fault; do not add standard electrolyte, or else make the electrolyte concentration increases, shortening the life of a car battery. Note that the electrolyte level is not too high, to prevent charging and discharging process of a car battery factory electrolyte spill, causing a short circuit fault. After adjustment of the liquid level, automobile battery charging response more than 0.5 hours, distilled water was added so that the former can be mixed with the electrolytic solution evenly. Otherwise, it is easy to make a car battery in winter ice inside. 4.5 car battery load voltage checks on used car battery car battery load voltage tester to check. Method: the two clips car battery tester were caught in the car battery 2 pole column (labeled "+" clip connected to car battery cathode, marked "-" clip then negative), press the start button requirement within 5 seconds, the car battery tester pointer should stabilize at a certain scale value. 4.6 Check the vent is smooth car battery is charging, the electrolyte density will increase and cause decomposition of water to produce hydrogen and oxygen, the whole car battery temperature will rise, accelerating the volatile hydrogen and oxygen discharged from the vent . If the vent plug, should be clear to prevent hydrogen and oxygen produced in the car did not break out the battery, causing the air pressure increases and the expansion of the electrolyte resulting in damage to the vehicle battery.
