#CarBattery

(Yes, this is the third consecutive post about batteries, so please accept my apology and I promise next week will be a different subject. -SM)

Sajeev,

My daughter is at college 200 miles away from me. She called me on the way to work and said that she thought her battery was going dead, because she got the dreaded “clicking” noise while trying to start it. The battery was replaced about 3 years ago, and the alternator and starter were checked and found to be ok.

The car is a 2007 Honda Accord EX-L with 95k miles on it, all service done by the dealer, timing belt changed at 75k, all fluids, everything up to date (I always took it to the dealership; I know I overpaid, but it has a pristine service record).

So I’m about to order a battery from an auto parts store that will install it for no charge, I’m cool with that, but is there any advice on what type of battery I should get? I’ve picked one out, it has a 1-year replacement warranty. Should I spend more, or do I just plan on replacing the battery every 3 years or so?

The car is pristine, she learned how to drive in that car, and I hate to see her sign up for a new car loan when I’ve had friends that have got 150k + service out of these cars. Also, I’ve read about putting vaseline on the terminals, etc. Do any of these tricks extend the battery life?

Sajeev,

Tonight, while driving on the interstate, the tire pressure warning light came on in my ’15 Honda Fit, then the ESC light came on, then the power steering warning light came on, and then the info display said to check the charging system. Everything seemed to be working just fine, though. I pulled off to check the serpentine belt, which was intact so I started searching on the internet for the symptoms.

According to the forums, it’s sort of a known problem that’s due to glitches in the electrical system causing erroneous fault codes. Dealers usually try replacing the alternator, which doesn’t help. The alternator harness, the ABS sensors, and the injectors/coil packs have all been mentioned in the forums as fixing the problem.

I’ll check all the connections in the morning, but in the meantime I’m leaning towards a faulty ABS sensor, since those are used for the TPMS in my car, not an actual pressure transducer, and the first light that goes on is for tire pressure. Also, the check charging system warning was intermittent.

What do you think?

I just recently had a dead battery on the Town Car, so learning how to properly jump start a car battery has been on my mind. I’m telling you, there’s a lot to say on this subject once you get into it!
