Hello,
i own a 2015 honda civic lx 4cyl auto trans.
Heres the story...the day i got my car the dealership put a new battery in the car. I didn't think anything of it. 6 months later, it's mid summer, went to start my car wouldn't start. No click of an attempt to start but if you leave the key in the on position every light comes on. That same day, i jump started my car, drove it for an hour none stop on the back roads. Came home turned the car off, went to start it again, no start. Next day it went to the dealership and they said it was a dead battery.

1year and 6months later the same thing happened. This time its mid winter but, it was 45° out that day. Took it to the dealership they claimed it was a dead battery. They said they tested for shortages in the car and they said there was a draw coming from somewhere. They kept it for a few days, gave it back and said it fine.

Additional information..its a lease and this all happened within 2 years of having the vehicle.

Please help!

Sounds like the dealership narrowed it down to a parasitic draw that's intermittently draining the battery. I assume they tested the alternator, correct? An intermittent problem and a parasitic drain can be very difficult to isolate and unless the problem is happening while being tested it may be all but impossible to find. The next time it happens, if possible, have it towed to the dealership without trying to jump or charge it. It's under warranty and the tow itself may be free via warranty or insurance.

Also, Goggle search your car's year for parasitic drain issue so you can talk about or printout possibilities for the dealership mechanics. Link to Google search: https://www.google.com/search?num=50....0.K88L0XxQGUA

Batteries can fail in several different ways, and sometimes without warning and cannot be predicted.
Batteries are always hit or miss. Some don't even make it off the new car lot (usually because sales department kills them)


if a battery is ran down it shortens its life expectancy, leaving it for long periods in a weak or dead state shortens its life dramatically

if a weak or dead battery is left in the cold it can freeze solid and that usually ruins it.


Had a new car with less than 2000 miles with a bad battery, it would drain itself to the point the car wouldn't start in 30 minutes---took it out of the car and charged it up til it passed the test, let it sit for a couple hours on the floor and it failed again without being hooked to a car!

Drains are usually (but not always) consistent and repeatable unless it's caused by operator error like leaving a map light on or the trunk open... Sometimes the car actually causes it to happen at seemingly random times but consistency would be far more frequent than a year and a half apart.

Makes me think it may just batteries that took a crap early. If a new battery under warranty fixes it, that's great.
You've got a year to go on your lease? it won't be your problem later on LOL

Never hurts to pop caps and inspect levels, electrolyte just above the plates is correct)

It is not easily done with all the stuff in the way these day.

3-4 years is the new norm.
