After this battery was properly cleaned and all systems checked, it was sprayed with an Anti-Corrosive agent to keep it and electrical components protected. This small amount of maintenance is enough to keep it running well for a longer lifespan, saving time, aggravation and money!


Notice the corrosion built up on this battery that was recently in the shop. First order of business is to properly clean the corrosion with baking soda, water flush, then sand down the terminals with a steel brush for a great connection. We then perform a charging system test, load test and voltage test. Do not do this at home without proper hazard protection as the materials are highly corrosive poison and gasses.

Battery Care:


There's nothing but a loud buzzing noise coming from under the hood when you try to start your car. Jumper cables get you up and scurrying to work--but you need another jump to get home. Time to pull some maintenance on the battery.

Automotive batteries have a finite life span. Undercharging, overcharging and heat all team up to degrade your battery. Poor electrical connections make it more difficult for even a good battery to do its job.

W begin any battery maintenance program by checking open-cell voltage with a battery tester or a voltmeter. With the battery fully charged and all electrical drains-dome light, warning buzzer, etc.-shut down, the voltage across the terminals should be 12.5 to 12.6 volts. If the battery is not completely charged, but still adequate to turn over the motor, you may see a voltage closer to 12.0 volts.

If the battery shows less voltage or won't take a charge, it's time to get out the hydrometer. This device checks the proportions of sulfuric acid and water in the electrolyte, which is a precise indication of the level of charge.

We then add distilled water to any cells in which the level of electrolyte isn't touching the bottom of the fill port.

If the level of electrolyte is very low, we most times suspect a charging system that's generating too high a voltage and is overheating the battery. The maximum voltage we should see across the battery terminals with a fully charged battery and an engine running well above idle is about 14.6 volts.

Another cause of low electrolyte is excessive heat. Sun Belt drivers should top up battery levels regularly because underhood temps will climb high enough to drive water out of the battery very rapidly, even if the charging system is doing its job correctly.
