Step-by-Step Guide to Fixing a Broken Battery Post
Follow these steps to fix a broken battery post:
Step 1: Safety Precautions
Before working on the battery, ensure your safety by following these precautions:
- Put on safety gloves and goggles to protect your hands and eyes.

- Ensure the parking brake is engaged.
- Disconnect the negative terminal of the battery first, followed by the positive terminal.
Step 2: Inspect the Battery Post
Carefully examine the broken battery post to assess the extent of the damage. Look for any cracks, fractures, or signs of corrosion. If the post is severely damaged, it may need to be replaced entirely. However, if the damage is minor, you can proceed with the repair process.
Step 3: Clean the Battery Post
To properly clean the battery post, follow these steps:
