Every year this beautiful 2012 Honda Accord EXL with only 27,000 miles ends up with a dead battery. Why?

In this video, I walk through the step-by-step diagnosis using my Topdon BT200 to test the EFB battery (935 CCA), and — spoiler — it fails.

Most people don’t realize that letting a car sit through the winter without disconnecting the battery slowly drains it below 12.4V — killing your battery over time.

In Part 2, I install a GAMA battery disconnect to fix this once and for all.
You can buy it here: amzn.to/4mujbQe
for $13

✔️ Real car problem
✔️ Simple test
✔️ Easy solution

Stick around for the fix in Part 2!
