How to fix a 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.
How long does a car battery last?
The normal life span of a car battery is about 4 years and knowing how to fix a car battery effectively may increase that number. If you own a fairly good quality lead-acid battery, you can use the acid and water method several times, but after some time, a process known as sulfation kicks in.
What to do if acid is completely gone?
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.

Why is my car battery dead?
A common cause of a dead car battery is simple user error. Either you've inadvertently left an overhead light on, left something charging in the accessory power source, or used too much accessory power when you've only driven a short distance. That means a lot of your battery's power was used when you started your vehicle, but your alternator, which returns power to your battery, didn't have enough time to juice up your battery fully.
What causes a dead battery?
Finally, a dead car battery could be indicative of corrosion on your battery terminals. These are the posts that connect your battery to the rest of the charging system. At times, corrosion — which looks like white, ashy deposits — builds up between the terminal posts and the battery cables and can cause a reduction in the flow of power in your vehicle. You can use a wire brush and baking soda to remove corrosion from your battery. However, if it keeps occurring, this might suggest that either your battery, battery cables, or terminals need to be replaced.
How to remove battery clamp?
The battery clamp holds the battery in place. Unscrew it with a wrench or socket to move it out of the way. Frequently, the battery clamp will be three pieces that are attached but independently mobile. So, if the clamp seems stuck at first, try to move the clamp's sidearms up and down to remove them from the battery tray at the bottom. Once they're free, the entire clamp will quickly come off.

Your owner's manual will give you a clearer understanding of where your battery voltage should be, but in most cases, you're looking for approximately 12.6 volts. A battery might need replacement if its volts suggest it's gone bad.
How to remove negative cable from battery?
Using a wrench or special battery pliers, detach the battery's negative cable by loosening the nut. If there's a lot of corrosion that makes this difficult, you can clean it away either with a solution of baking soda and water or with a little automobile-safe lubricant.
How to tell if a car battery is bad?
If your battery isn't dying, but you're concerned for your battery life, look for the sound of a lazy engine — meaning it takes longer to turn over when you're starting your vehicle — or flickering overhead lights when you're starting your vehicle.
