Battery problems

I keep my 911 C2 in the garage during wintertime. Trouble is(well known) after a couple of weeks, there is not battery-power, no alarm etc. Does anyone know of a smart solution? Itīs a public garage(with steel-cages), soo the trouble is: I have no outlets available.Wayne told me about a devise to plug inte the cigarette-lighter, but I believe that you have to have access to electricity from "outside". Is there any way around this problem?Help!

The easiest solution would be to install some sort of battery cutoff switch. They're inexpensive and easy to install. You're correct about a battery charger-you need access to an electrical plug.

I recently installed a new battery in my '92 C2. I had my mechanic run an electrical system diagnostic to make sure it was only the battery. He told me that I had a bad ground strap ($15 part), which he replaced. He also told me that the C2's tend to draw a higher amount of power from the battery when not running compared to the newer 911's. That may explain why you're battery is going dead after not being driven a few weeks.

If you have no access to a power source, its getting difficult.

If the battery stays in the car, its most likely dead after a while.
Even if you disconnect it, it will discharge, and, depending on your general car's condition, will eventually not be able to start the car.
If you are facing this situation, one solution is to buy a new battery with a very high cold start rate (> 600Ah).
I have been quite successful with this. Start up after 6 weeks-no problem (connected to radio and clock, no alarm, poor running engine with a biiig puff up each time).

If you can get a power source nearby, a trickle charger will do fine. Either connect to the battery or to the cigar lighter. The harness is very thin, so you can bend it through your door or trunk seals.

Hope this helps.
