How to Fix and Prevent Exide Car Battery Acid Leakage

If your Exide car battery is leaking acid, don’t worry. You are not alone. Many car owners in India face this problem. In this post, we will explain in very simple ways how to fix and prevent battery acid leakage.

In Exide batteries, acid leakage usually happens when:

• The battery is overcharged
• It is damaged from the sides or top
• The battery is tilted or shaken during driving
• There is a crack near the terminals
• Or it is a manufacturing fault

How to Identify Leakage in Your Battery

Here are some common signs:

• You see wet marks or white powder near battery terminals
• You smell something like rotten eggs (acid smell)
• The car takes longer to start
• The battery looks bulged or has liquid on the surface

If you see any of these signs, it’s better to check the battery immediately.

How to Fix Exide Battery Acid Leakage

Always wear gloves and eye protection. Battery acid is harmful to skin and eyes.

Step 1: Clean the Battery Area

• Take a cloth or old toothbrush and clean around the terminals.
• Use a mix of baking soda + water to neutralize the acid.
• Don’t touch the liquid directly.

Step 2: Tighten the Battery Caps

• Sometimes, the caps (tops) are loose. Gently tighten them.
• If they are damaged, replace them.

Step 3: Check Battery Terminals

• See if the terminals are cracked or loose.
• Apply petroleum jelly or grease to stop further corrosion.

Step 4: Seal Small Leaks

• If there is a small crack, you can use epoxy glue or battery sealant to cover it temporarily.
• This is only a temporary fix—you may still need a replacement.

Step 5: Visit a Mechanic or Battery Shop

• If leakage is serious, visit a local Exide service centre or mechanic.
• You might need to claim warranty or buy a new battery.

How to Prevent Battery Leakage in Future

Follow these tips to avoid this problem again:

✅ 1. Install the Battery Properly

• Use proper clamps and battery tray

✅ 2. Avoid Overcharging

• Use a smart charger if you charge the battery at home
