How To Avoid Corrosion On Battery Terminals

Following on from our post on Maintaining Your Car Battery, here we focus on how to avoid corrosion on battery terminals. Car batteries are used to start a car and power the electronic aspects of the vehicle. They supply power that is used to ignite the fuel before your engine starts up. But when the battery terminals get rusty, there won’t be proper flow of power which makes your car useless for the moment.

Take a look at the battery to check if there is any white powder on the battery terminals. If there is, then, it’s corroded. Corrosion can delay your car engine from starting up or not starting up at all. The average lifespan of a battery is at least four years. This may vary from one brand and capacity to the other, having in mind that proper cleanup and maintenance is done regularly. Below are some tips on how to stay away from corrosion on battery terminal.

Safety Tips For Cleaning Battery Terminals

To avoid touching corrosive materials or to avoid any contact with the corrosive material, it is recommended that you use hand gloves, protective goggles, and a work smock. Make sure not to touch the metal parts and frame of the vehicle other than the battery terminals to avoid putting the battery under the danger of short-circuiting.

Be conscious of any fault or leaks in the battery, in case of any cracks; then the battery needs a replacement. So also, replace or repair any damaged wires you notice.

If your vehicle is a new one, then you’ll have to be very careful as disconnecting the battery might be a little bit tedious.
