Using a mixture of water and baking soda, clean off the outside of the battery. Wear protective gloves and eyewear to prevent contact with any loose acid.
Most batteries have two small plastic caps that cover the six cell holes. Remove these caps, and place them aside. Carefully remove any dirt or debris from the areas that were previously covered by the caps. It is important that no dirt falls into the cells.
Using distilled water, refill all of the cells up to about 1 inch from the top. Do not use tap water, as it contains minerals that can ruin the inside of your battery through corrosion. Once all of the cells are filled, replace the caps.
Cycle the battery through multiple charges. On a conventional charger, it may take a number of cycles to fully restore the battery.
The most common signs of a bad car battery include the vehicle backfiring, dimming of headlights while driving, problems with electrical systems in the car and the vehicle not starting. These issues arise at any time. It is important to monitor the lifespan of a battery and ensure that connections are not corroded during that period.Full Answer >
Most car battery explosions are caused by thermal runaway, which is when the battery overheats, causing its cells to break open. Usually, one cell starts a chain reaction in which other cells rupture. A swollen battery is a less serious manifestation of the thermal runaway effect.Full Answer >
Car battery chargers connect to car batteries with positive and negative cables and clamps, which are usually red and black and marked with a plus and minus sign. The positive clamps connect to the positive posts on the batteries themselves, and the negative clamps connect to vehicle frames or some other unpainted surface away from the battery.Full Answer >
