Hey, guys.

I apologize if there is a similar post. I had no luck searching but it has also been a few years since I've been on here.

I have a 2007 Honda Odyssey and replaced the battery a few months ago. Yesterday I went to go start it and it was completely dead. When my wife got home we connected the jumper cables (alarm went off) and the van started right up. I let it run for a little bit to charge the battery a bit. About a half hour later my wife went back out and the thing was completely dead. We left it like that over night and first thing this morning jumped it again (alarm again). Again, the van started up like there was no problem once the cables were connected.

The alternator appears to be working just fine. The only difference in the vehicle lately has been the noticing of a single beep after opening the driver door. We've had the vehicle for a few years now and have never heard this.

Thanks for any help.

 

I hope you had it fixed by now. If the battery dies within a short time, there is only two possibilities: the battery is bad or your car has a power drain or a short. You should bring the car to the dealer, they can give your battery a test for free. If the battery fails the test, you should bring it back to where you bought it and get a new one for free if it is less than 12 months. If the battery passes the test, there is a short or a drain on your car. This can be as simple as you forget to turn off the interior light or some accessory. Otherwise, it will require the dealer to tracks it down. When I first got my Odyssey, the battery dies in less than 6 months, I brought it back to the dealer and they replace it with a new one under warranty. As it turns out, the power doors drained the battery fast if you used the doors and only drove short distances. The battery was never fully charged and eventually died. However, I had never lost a battery that fast so when it is time to replace my battery, I won't go back to Honda.
