Remove Old Battery and Clean Components

What happens here

Carefully lift the old battery out of its tray. Batteries are heavy, so use proper lifting techniques or a battery lifting strap if available. Once the old battery is out, you will likely see a significant amount of corrosion and rust in the battery tray and on the removed hold-down components. Apply a rust-penetrating catalyst like 'Rust Breaker' to the corroded bolt and brush it thoroughly with a wire brush. Clean the clamp and any other corroded parts similarly until all rust and corrosion are removed. The video highlights a broken battery mount, which might be a result of severe corrosion and difficulty in removal. This step also includes cleaning the battery tray itself to remove any accumulated corrosion, dirt, or debris to prepare for the new battery.

Goal: Remove the old battery, then clean the corroded battery tray, hold-down bolt, and clamp using a rust-penetrating catalyst and a wire brush.
