Why is there white, crusty buildup on my Ascender’s battery post?

If you notice white, crusty stuff around the battery terminals of your Ascender, it's likely corrosion.

This buildup can interfere with the electrical connection between the battery and your Ascender’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean a corroded Ascender battery terminal?

Regularly inspecting and cleaning your battery terminals will help keep your Ascender’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
