Background:
- 5+ years old (2019) and 126,000 miles on the odometer.
- When I had the battery checked by the local auto parts store a few months earlier, the battery health was at 80% (still okay).
- Recently and periodically, the engine has not been cranking and starting immediately. Colder temperatures results in higher current draw... highlighting a weak battery.
- The battery voltage (vehicle OFF) was at 12.1V... a healthy battery should be higher.
- AGM (Absorbent Glass Mat) type battery
- Size H6-AGM / Group Size 48
- try to find one with "760 CCA (Cold Cranking Amp) / 950 CA (Cranking Amp)" ... Everstart at Walmart or Interstate at Costco are probably the least expensive options
Here is an existing DIY video for the Honda Pilot (same for the Passport 2019-2025?).
Notes from my replacement:- Only tools required are a Phillips screwdriver, 10mm long socket, ratchet and vacuum.
- An easy DIY, but you may need a little help with removing and inserting the 46lb battery.
- The battery sits inside a plastic case.
- There is a exhaust fan on the battery enclosure to keep the battery cool (1st photo).
- There is a lot of debris that accumulates inside the enclosure! I believe that debris enters via the upper left corner (2nd photo).
- It would be prudent to clean out the enclosure, especially in hot climates (heat kills batteries).
