Battery-Winter Storage

Cunnos · 11-22-2010, 04:42 PM

I know there are several threads about this but I wanted to get a few opinions regarding the battery. I just got a great deal for winter storage up here in Boston but the problem is the storage doesn't have any outlets.

Question 1.
If i take the battery out apparently it can cause harm to the car (resets throttle/gear settings), has ANYONE experienced this? If so, what happened?

Question 2.
If I leave the battery in for 4-5 months without starting the car will it really be that harmful? Wont it recharge itself when I start up again in the spring? The storage is not heated either......

yah, unless you have deep cycle batteries your factory battery will be weaker next time you charge it. ive toyed with batteries in the past and in general, once your battery is drained it will only recharge about 85% or less at best. your CCA drops too. keep doing that a few times and your battery will no longer start the car effectively and burdens the alternator.

i would remove the battery given your choices and recommend you put a battery tender on it while in your house.

Good advice.

Your best bet is to get this. I have one and have used for years, no issues, easy to plug in.. no harm to your battery, and works fine with Euro and Japanese cars.

Check it out here on Amazon.. Amazon.com: Battery Tender 021-0128 Battery Tender Plus 12V Battery Charger: Automotive
