John, As a builder of the DeLorean alternators D110 & D140 customers think that alternators charge batteries and will let them Idle as if it's charging the battery. In actuality what is happening the starting of the car is slowly drawing down the battery faster than it could charge it. Think of a 10 amp charger would take 8 hours to charge a almost dead battery. That's about how long the alternator would take to charge the battery if it could hold up to charging for that long before it got so hot it would burn up. Alternators are made to top off the battery and not really charge them up. The old time generators back in the 50's and 60's were chargers. Use what ever kind of battery you like, but keep it charged. Battery cut of switches I have on my web site will stop any drain, but batteries have a natural drain down from none use. This where a float charger comes in.

When it first failed to start a few days ago, I charged it up with a portable charger and it started up. I ran it for a while but when I went back to start it a day or two later, the battery seems completely dead - just the solenoid click and a flickering of the dome light. This time I couldn't even jump start it. My questions: - What are some recommendations on a replacement battery that might hold up better to a harsh New England winter in storage? I don't have room in my garage for it so it's stored in a non-climate controlled storage unit. - The storage unit does not permit any electrical outlet so trickle charger is not an option. Is there anything I can do before putting it into storage to prevent this from happening again? I don't want to go through this every year. Thanks.
