Bill, your link sells everything that has been mentioned.

If you have concerns, you might try talking to them. I've never heard of the Battery Tender Jr ever hurting anyone's battery; in fact, XViper has recommended it often and his winters are a lot longer than mine.

Let me add this, I cannot say for sure that my Battery Tender has cooked both of my batteries, but is sure is a coincidence.

I have used the same BT on motorcycles in years past, charging them off and on during the Winter months w/o issue. I have had the S2000 "charging" / "floating" for the past month, I disconnected it to go to work, a 25 minutes drive. Upon arriving at work I popped the hood to see the battery leaking.

Plug it in and forget about it all winter (6 months).

I'll sell you mine Bill. I don't use it anymore. It worked great when I lived in Ohio. I left it on full time and it turns itself on and off as needed.

Thanks Carm, what do you have?

I just bought a Schumacher at wally-mart for $20. I'm testing it out on the Healey battery to see if it works. I'd be interested in having two. I have at least three batterys that need to be maintained all winter.

I'm not convinced that battery tenders are necessary (nice, maybe, but not necessary). Each winter, I remove my battery, take it into the basement, and leave it on a shelf for 5 months. In the spring, I trickle charge it to at least 80%, then run it for another season. I still have the original battery in my '02, and I easily got it back to 80% a few weekends ago after accidentally draining it while working on some stuff in the car.

Maybe next spring will call for a new one, but it doesn't look like it as of now.

I don't think it is good to drain a battery, and I found out this year that when the battery dies it takes about 200 miles for all the emission systems in the car to work properly. I couldn't get an inspection sticker for two weeks.

I've been using a Deltran Battery Tender Plus for years. Works great! My lawn mower battery lasted 9 years even with 6 months of storage each year. I used to switch it back and forth between the car, motorcycle, and lawn mower. I just picked up a second one so I won't be switching as much. (Got it free when I spent $200 on motorcycle gear through an online special.)

Mine is from Griot's Garage. It's called the Battery Manager II. Here is a link to Griot's battery management selections. They no longer sell the one I have I guess. Looks like they now have the III and IV. I think mine was $60 new.

I know it's not good, but sometimes $$it happens.

My point is that if I'm getting 7 (at least) years out of a battery with no special care, and even a little bit of abuse, then maybe it's not so important to keep it charged all the time after all.
