Battery removal for winter (I know a bit late to be posting)


Recommended Posts

I just dropped off my '02 C4S at the dealer yesterday to get the ignition fixed. I was talking to the advisor about winter storage, because they had just brought in another car with a dead battery ("Good weather, everyone is finding a dead battery!")

What I did this winter was remove my battery from the car and put a charger on it. I thought that was the right thing to do. He advised me that I could have problems when it was put back in the car - potentially shorting things out or losing codes, etc.

Should I have not done this?

The reason I took it out is that I didn't want to have the charger sitting in the trunk, with the cord coming out and a cover on the car - don't know why, but I just thought it would be better with the battery completely out. I put the battery back in about every 3-4 and started it up and went for a short drive on a nice day, but that's about it.

Obviously, I won't be doing this any more this winter/spring, but I'm just planning for next year.

Thanks,

Eric

Purchase a good battery maintainer with cigarette lighter connector for next winter storage. You can keep the battery connected in the car without problems of losing codes etc. The best option IMHO.

I've been taking the battery out of mine for the past two years during storage without any problems. My brother works at a porsche dealership and warned me about disconnecting the battery. He said it can set off the traction control, psm, or other lights. My car is a bone stock 2000 C2 so I don't have anything fancy like traction control or psm. I have a battery charger that hooks directly to the battery and I have the porsche charger that goes to the cigarrete lighter but I still prefer to remove the battery so I don't have to run a cable across the paint of the car.

What he said.

No charger, just a maintainer as RFM suggested. I use Porsche version, but there are other good ones. Cord easily passes thru where side glass meets the door.

I guess I'll get a maintainer for next winter.

It's always good to have the charger around anyway. I was getting tired every spring of pushing my lawn tractor out of the shed and jumping it with my Audi!

Pushing the lawn tractor would be easier for me than lifting the P battery in and out of the trunk every winter. Battery maintainer is the way to go.

Where I store my car for the winter, there is no electricity. I have pulled the battery and connected a maintainer directly to it for many winters. Absolutely no problems upon re-installation. My car is an '03 Boxster S with PSM, etc. --Brian

It will not act as a full charger. Not even a trickle charger. You can/should put a maintainer on your tractor also. Its battery will thank you, and it will live longer. Batteries hate full discharge/recharges.

Battery Tender makes maintainers that have multiple cables.

I agree with RFM. I have been doing this for 3 winter hibernations. Plus, that alarm stays active.

Thanks everyone. Actually I should have clarified (not that it really matters) I do have a charger/maintainer (Schumacher SC-600A - 6/4/2 Amp Charger/Maintainer), but unfortunately, it doesn't plug into the lighter.

Thanks again for everyone's input.

I won't be worrying about it until next November.
