I keep my 66 in the garage over the winter. It's not a new battery but every time I go to start the car the battery is dead. Jump starting is becoming a pain every time I want to run the car for a while in the winter. Any ideas on how to keep the battery from constatly discharging?

Do you have the battery disconnected while in storage? There may be a slight draw on the battery and that combined with the cold weather could be the culprit. The battery itself could be going bad and the cold weather is not helping matters any.

I used the battery tender on my motorcycles all the time. Just be sure to get one that cycles itself on and off so it is not just a constant trickle charge. I have had both and now only use the switched one. Also, watch the water level as continually charging will cause the water to evaporate. Cost me one battery from not checking water. Another way would be to send me the car and I will drive it all winter for you and keep the battery from running down. SE Az. is nice weather......

battery tender would be a good idea. i always bring my battery inside between starts during the winter.

Had a new batt. in a car years ago, car sits in garage for week, batt. dead. Charge it, another week dead. Long and short of it was a BAD voltage reg., it was shorting or staying on all the time, draining the batt. Replace reg.next to radiator, car sat for long time after that and started right up.
Just another possibility.
