To measure the battery voltage accurately, the top charge must be removed. Achieving this involves switching on the higher lights for a period of ten seconds and then turning them off to allow the vehicle stay for about two minutes. Battery check begins by taking off the battery cover and unplugging both the negative and positive battery cables. The indicator eye at the top of the battery should be visually examined; it has to be black meaning that it should be charged if yellow or replaced in case of defects. Open circuit voltage is measured using a digital voltmeter, which should give about 12.6 volts for a fully charged battery. Charge your battery first if it is less than this value before you proceed with other steps. A load tester is next used to carry out a load test on your battery. Connect this device to your terminals, apply its load within fifteen seconds without letting your cells' voltage drop below 9.6 volts. When it is weak or defective, an indication will appear in a load tester's display window. During replacement of one's battery, check with dealer parts department or auto parts store that sells batteries so as to get accurate choice of battery required in such cases. Remove relevant trim panels and also loosen up the positive plus negative cables connected to my battery Remove relevant trim panels and also loosen up the positive plus negative cables connected to my batter Ensure that there is no corrosion beneath your cells after lifting them out carefully as they are heavy Avoid being careful when lifting out my cell due to its weight; look at underneath if corroded clean It should first connect new batteries and lastly attach negatives.
