Long-term battery loss of freight cars will cause the automobile engine to fail to start normally after flameout. 1, common diseases are an excuse for oxidation, which is also commonly known as "cap alkali". Rinse with boiling water, re-tighten the terminal and dip a little butter on it. 2, since the run, parking for a long time without negative flat. It is necessary to charge in time to ensure sufficient electricity. 3. Don't use high-power appliances such as headlights and stereo when the engine is turned off, so as to avoid feeding. At present, most of them are maintenance-free batteries, but some island cars are still using old-fashioned batteries (there are several small covers on the top that can be unscrewed), so it is necessary to fill the battery liquid regularly. It is enough to buy two bottles of battery replenisher (the size of one bottle of Xijieling) at a time. First, unscrew all the small lids, but don't put them anywhere! Then carefully inject the supplementary liquid into each small hole (the liquid level is only one centimeter away from the hole edge), and then rotate the small cover back after adding it. !
The inside of the battery is 3%-5% sulfuric acid solution, so the lower cover can't be misplaced, and the supplementary solution is also sulfuric acid solution, so be sure to fill it up carefully!
Suggestion: If the battery is not maintenance-free, please go to the auto repair shop to refuel it to avoid accidents.
