🔧 Battery Replacement

On your Explorer, the battery is under the hood. You’ll disconnect the old battery, remove the hold-down, swap in the new battery, and then reconnect everything in the correct order. This is a straightforward job, but correct cable order matters to avoid sparks and electrical issues.

Difficulty Level: Beginner | Estimated Time: 0.5-1 hour
