The life of the ordinary automotive battery is generally in two years, and the life of the vehicle battery is doubled by ordinary batteries. But in real life, automotive batteries often cannot use the design life. There are many reasons for battery damage, such as over-discharge, no charging for long time, no electrolyte or electrolytic solution is too high, contaminated with dirt, and now the author has analyzed some common causes, I hope to use it properly. Maintain the car battery help.
1, polar pile and collet size do not match. When the installation is too loose, since the current is too large, the contact surface is too small or the contact is poor, it is easy to burn the pole column; the installation is too tight, the mammoth is smashed, and it is easy to damage the pole, causing the battery to scrap.
2, unreliable fixation, the vehicle produces severe vibration in travel, calendering the enamel, housing and cover.
3, the charging current is too large, causing the active substance on the plates to fall out, shorten the battery life.
4, the starting time is too long, so that the battery is dramatically discharged, resulting in a polar bending, the active material cracking.
5. Long-term placement or use in the absence of insufficient charging, vulcanizing the plate.
6, the electrolytic liquid surface is lower than the plate, which causes the electrode plate to expose the liquid surface and is exposed to air. During driving, the electrolyte is fluctuated up and down, and contacts the oxidizing moiety of the plate, resulting in a plate vulcanization.
7, the electrolyte contains impurities, mainly for distilled water and the metal container such as copper and iron when the electrolytic solution is formulated. These impurities will form in the battery“Small circuit”To allow the battery to accelerate its own discharge.
8, wiping and maintenance is not in time, the overflowing electrolyte is deposited on the cover, resulting in a polar pile and causing corrosion, producing an oxide, thereby forming a passage on the cover, and there is a self-discharge phenomenon.
9, the new battery does not perform initial charging or direct large current charging, will also shorten its service life. The new car battery can be installed after the end of the electrolyte and the method of small current must be used.
10, ignore the venting hole of the battery, if it is not turned on, the gas generated in the use cannot be discharged, and the battery will explode due to high pressure.
11. When the battery is added to distilled water, it is long and not charged, causing the battery self-discharge or damaging the polarity of the battery.
12, the charge capacity of the battery does not match the engine, resulting in early damage of the plate.
