Weekly Checks – Battery Level

Posted by:

ELECTRICAL SYSTEM  – Charging system – Battery

The purpose of the battery is to receive the charge from the alternator. This charge should be received in a perimeter of 13.8-14.2 volts. If this charge is lower, eg 13 volts, the battery will be affected. If the charge is higher than 14.2 volts the battery will also be overcharged and this will shorten the life of the battery. The battery should be checked to make sure that it is receiving at least 13.5 volts of charge. It also should be checked with the headlights on as this will ensure that the battery is receiving a charge under load.


You need to make sure that the battery is secure and that the water level is at the correct height. The best way to check this is over the plates and under the caps. An overfull battery will create more vapour and will start to eat any metal including the battery cradle. If the battery cradle has a white powdery substance around the terminals or battery poles or cradle, hot water and/or baking soda is used to eliminate this. Baking soda is a neutralising agent on the acid, so it will take longer for the acid to return to the battery poles and the battery cradle.


The battery should cost between $50.00-$120.00. The best battery to buy is one that you can service by filling it up with either tap water or if you’re not sure of the quality of the water, distilled water. The battery level must be maintained. If it is too low and has been neglected for a long time and you decide to put water in it then this may affect the battery. Batteries should last at least 18-24 months. Keep your warranty if you need to have it replaced within the warranty period as batteries do have a high mortality rate.
