Toyota-Lexus-Subaru-Honda Battery Service

Battery Service The battery tends to give off sulfuric acid vapors as it goes through its charging and discharging cycles. This acid tends to cause the battery terminals and connections to corrode. It can also create a film of acid across the top of the battery which results in the battery tending to discharge across the surface, and which causes the battery to go dead more quickly during times of prolonged sitting.

In addition to the terminals getting the obvious blue and white crystalline build-up that needs to be cleaned off during a battery service, the metal surfaces of the battery terminals and clamps can become oxidized and become ineffective at conducting the large amounts of electricity needed to start the car. This doesn’t look that noteworthy-just kind of a dark gray skin that develops on the surface of the lead-but it needs to be scraped off till shiny.

We like to spray liquid grease on the terminals to protect them against further corrosion. I don’t like those little felt pads that some shops install around the terminal and under the clamp. They lift the clamp up so that it’s not able to seat down all the way, and with the tapered terminals, it’s not at all uncommon to see the clamps end up being loose on the terminal and unable to be tightened down properly with the felt in place.
