Battery disconnect switch issues?

[dzcues]

I've had troubles with my battery discharging when in storage. Sometimes it will survive 6 weeks with no problem. Sometimes I'll find it dead after 2 weeks. I suspect the problem lies with the alarm system but nobody has been able to prove or disprove that.

So, I installed a switch to completely isolate the battery whenever I expect the car to be idle for longer than a week. I understand that my clock & radio presets will reset to their defaults but somebody just told me that the car's computer will lose its "adaptive learning"???

Can anybody please explain:

1. exactly what that is
2. will I really lose it?
3. how long of a disconnect does it take to lose it?
4. how long will it take to "re-learn" whatever it forgot?
5. why did no one tell me about this earlier?

Install a quick disconnect for a battery charger. The new solid state units can be left connected all the time they'll keep your battery in top notch condition. I still disconnect my battery form the car when leaving it for any length of time. Whatever it needs to remember isn't going anywhere.

A Battery Tender should make all your troubles disappear.

Yes, disconnecting the battery will reset the ECU.

Use a Battery Tender all the time with their ring terminal harness hooked up to the battery posts (in fact have one for the Mustang, one for the riding mower and one for the 4 wheeler)

Thanks for the suggestions but, unfortunately, a trickle charger is useless as there is no power where I store the car.

*Unless somebody can tell me where to find a 750' extension cord

sounds like you need a spool of wire, conduit, and a trencher lol

You could always use a solar powered trickle charger. They cost under 100 bucks.

Don't worry about adaptive learning. My car gets stored w/o the battery every winter and it's a complete non-issue.
