I'd have to disagree with you Pauljo. I got one last year for my Honda Shadow. It does work well but it will lower the water level in the battery (which is usually a sign it is overcharging). I have to add water at least once a week if I leave it on all the time. I hooked it up to a timer so it only comes on for an hour a day.pauljo said:Battery Tender JR. A good smart charger. Plug it in and forget it - it won't overcharge the battery.
Paul, my '04 650 battery has liquid electrolyte but is sealed and requires no maintenance. The Service Manual cautions "........make sure to use the charger specially designed for MF battery."pauljo said:But I think these new batteries are gel filled, so water evaporation as well as water loss from charging should not be an issue
Harley owner? Bite your tongue! :lol: Not packing it in - just making sure my battery keeps it's charge in Jan. and Feb. so it can handle my electric jacket and gloves.drspencer48 said:What!? Nov 3d and your talking about packing it in for the winter? Are you a former Harley owner?
Yes it is compatible. I just waded through the FAQs on the Battery Tender site. The BT Jr is compatible with both the AGM (Absorbed Glass Matte) and Gel Cell types of maintenance free batteries. I am not positive which type we have, but after reading the material on different battery types, I'd guess that they are AGMs. They seem to be the most popular for power sports applications.DonRich90 said:Oooops! Just as I hit the "Submit" button I realized MF probably means "Mainteance Free". I'm still not sure my Battery Tender Jr. is designed for a MF.
The Battery Tenders are not trickle chargers though. They explain the differences in the FAQs on their site.dero said:.
Yuasa do not recommend leaving a battery on trickle charge all winter, apparently it causes sulphation which will eventually kill a battery, it can also boil away the electrolyte if the trickle charge is too high.
Right.drspencer48 said:There's nothing more exhilarating than cruising on a luke cold December or January day! If it ain't snowing it's riding weather. Just take a cruise on a frosty Sunday morning, then come home and sip some hot toddy and watch the football playoffs - nothing better!
Paul, you were right. I e-mailed Deltron yesterday and they replied today saying that the Battery Tender Jr is fine for MF batteries. Thanks.pauljo said:The Battery Tenders are not trickle chargers though. They explain the differences in the FAQs on their site.
