[User Experience] Dont Hit your car Battery Terminal! — My Toyota Alphard Got Damaged!

alp_specialist

Recently, I had to change the battery on my Toyota Alphard.
When the terminal was stuck, I tapped it like I used to — just a small knock to loosen it.
Big mistake. A few days later, my engine wouldn’t start. I opened the hood and found white powder all around the battery area.

After further checks, I found out:
The battery case had cracked slightly, leaking acid.
This acid dried up and became white corrosion powder, which had already started to damage:
- Terminal wires
- Battery tray
- Even nearby metal brackets

Worst part?
⚠️ Engine bay rust, unstable voltage, and intermittent starting problems.

✅ What I’ve learned since then:
✔ If the battery is stuck — don’t knock it. Check if the terminal clamp is too tight
✔ After replacing, apply anti-corrosion grease to prevent white powder buildup
✔ When unsure, it’s honestly safer to let a qualified technician handle it, especially for Alphard / Vellfire / hybrid models

I’m sharing this in case anyone here drives a Toyota Alphard, Vellfire, or other MPVs.
A small mistake can lead to much bigger issues, especially with recond vehicles or older batteries.

Have you ever dealt with white powder on the battery? Or your car refused to start even after replacing the battery?
Feel free to share your experience or ask questions — let’s help each other avoid unnecessary damage.
