Car Battery Terminal Corrosion
After opening engine hood you may notice strange blue / turquoise colored fungus covering battery connections. Chemical reaction between acid vapor escaping from the battery and copper or steel terminal connectors can produce corrosion on the positive and negative posts of the battery.
Battery Corrosion and Acid Cleaning
Before you start scrapping away battery corrosion you will need basic personal protections and safety equipment. Corrosion and oxidation build up on battery terminals is very corrosive and flaky. If it comes in contact with skin or clothing it will burn and deteriorate quickly. To safely brush off and scrape the corrosion, you will need safety glasses, gloves and face mask.

Over time due to acid corrosion – battery terminal material becomes eroded and weak. Damaged battery cable connectors may break apart when trying to install a new battery. While battery replacement is not a complicated task, if you have a lot of corrosion around battery post, make sure you can see the condition of the battery clamp. If battery terminal breaks and you cont have a replacement terminal, you won’t be able to reattach the cable and start your car.

Battery terminal cleaning with built-in BMS sensor
Vehicles like Ford, BMW, Volkswagen are using BMS (Battery Management System) to extend battery life and monitor battery condition. BMS sensor is a small sensor located on positive battery terminal or clamped around positive cable near battery. In case of extended corrosion damage the terminal or sensor gets damaged and complete positive battery cable must be replaced.
