^{FIX CAR BATTERY}

A safer and more effective way of how to fix a car battery is by simply topping off its distilled water and acid levels. This method only works in the case of lead-acid batteries and should be handled with extreme care due to the toxic nature of car battery acid. By filling up a wet cell lead-acid battery with the right amount of water, you can get it to work again even if it was unable to create a sustainable charge in the past. However, it’s important to avoid adding acid unless the battery actually had some of its acid spilled out. Otherwise, topping it off with distilled water and using a charger to mix the acid and water should suffice. Keep in mind that most newer batteries are a sealed-cell design, and topping off the electrolyte levels in the cells isn’t even possible.

To complete this method, you have to first measure it. If it’s completely gone, the voltage it gives off will be minimal. The next step is to top it off with distilled water (if possible) in order to activate the acid. You may find the voltage increasing slightly after this step. If acid was spilled, the right amount of sulfuric acid should be added to supplement it. Otherwise, after adding distilled water, simply kickstart the charging process and allow the chemical reaction to take place, so the dried acid can once again mix with the water.
