take care of ur battery

Although you need petrol to make an engine run, electricity is also an important requirement as, without this form of energy, you won't get the sparks to start combustion, nor be able to crank the starter motor to set the pistons in motion (unless you push-start the car). So a battery, which stores electricity mainly to help you get the car started, deserves more attention than it usually gets.

Care of a battery generally means keeping its fluid up to the right level. The level can drop due to evaporation and if it drops significantly, the cell plates will be exposed and their capability to store electricity will diminish.

Most batteries have lines marked on the sides of the opaque casings so you can roughly see the level of the electrolyte through the casing. There's usually an upper and lower limit - ensure that the level is within the two lines. You can also remove the caps and peer inside. If the level is high enough, you won't see the upper portions of the plates of the cells sticking out of the solution.

You don't have to disconnect the two electrodes at the top when topping up, but make sure that no sparks are created when you are handling the battery in any way. This means no smoking as well! Because of the chemical reaction inside, hydrogen and oxygen are given off and an explosion can result if there's a spark.

Use only distilled water. Tap water contains impurities which can become solids during the chemical reaction. These accumulate at the bottom of the battery and, over time, will interfere with the charging process and storage capability in the battery. Distilled water is sold at petrol stations and hardware shops (or you can distil it yourself). Never add sulphuric acid into the electrolyte.

When pouring the distilled water in, do so with care. The electrolyte contains acid, a highly corrosive and poisonous liquid. If the electrolyte overflows or splashes onto the casing, quickly wash it off with water (after capping the openings first). If you allow it to remain, corrosion will start.
