Piston Slap: Unfit to Charge… an Accord?

(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?

  • EBFlex "I've only filled the gas tank three times in 2500 miles"Assuming you went from 0 gallons to full (17.2), you have averaged almost 50MPG over those 2500 miles. 50 MPG in a Jeep Wrangler. To all of you EV nut jobs, tell me again how PHEVs are not the absolute best thing to happen to automobiles since the wheel. And tell me how they don't make EVs look like the awful play toys that they are.
  • MRF 95 T-Bird The Buick 215/3.5-liter aluminum V8 was one of GMs great engines. Unfortunately GM being GM in one of their greatest mistakes was selling off the tooling to BL. If they kept it around and improved upon it it would have been a fine motor for their compacts and midsize models through the OPEC oil crisis.
  • Chris P Bacon Not sure why a '21 is getting reviewed, because there have been improvements to the 4xe. I've got a '22 4xe Sahara. May 2022 build in High-Velocity yellow with a soft top. As soon as it was announced I knew I wanted to try it, not for the fuel mileage, but for the technology. I don't have a Level 2 charger, it charges fully overnight on the included Level 1. I see an indicated range of 27 miles regularly. Today it indicated 29 when I unplugged. I've only filled the gas tank three times in 2500 miles, a full charge costs me about $3 based on my current electricity supplier. I don't experience the rough transitions between electric and gas, so maybe Jeep figured it out? It's stupid fast when using all the power off the line. So much so that it will break the rear wheels loose when you stomp on it. I agree that plugin hybrids are the future. I see no need for a pure electric. This is the way to go.
  • RHD The word B R O N C O written in contrasting paint on the dashboard is quite unnecessary. The passenger certainly knows what kind of vehicle he or she is in. That detail is a big fail. The red and white Bronco looks great, especially with tires that have honest-to-goodness sidewalls on them.
  • Luke42 Aren't those trim levels just different colors of paint?That's what they sound like, at least. 🤷‍♂️
