I have three "Enerwatt 1.5 amp" tenders. Working perfect for the past five years

 

I keep the bike on the HD tender, and my RZR and the wifes summer car each on Battery Jr Tender full time. Never an issue with either brand, and always a fully charged battery.

 

I swear by the Deltran Battery Tenders. I have one of the older 2 Amp units, and three of newer 3 Amp units which I keep on my dirt bikes and Glide all the time. I bought all of the newer ones at Costco. They have some great deals from time to time, and even their regular price beats most of the competition.
My brother has an old garden tractor that he only uses to plow snow with on his property. He now keeps it on a battery tender and he's had the same battery in the tractor for over six years. Prior to buying the battery tender he says his tractor battery would sulfate and go bad about every two years.
Here's the link to the one Costco is selling right now: https://www.costco.com/battery-tende...100519712.html
And, no I don't work for Costco and I'm not affiliated with them. I just have a membership and buy stuff there when they have a good deal.

 

I like the 750ma Juniors, I have a couple of them. Just a cord from the transformer on the wall, and they are usually pretty cheap. No need for the bigger ones on a bike.

I have the 3 amp on my old Jeep that sits around.

Same here. I got a LithiumLife for my RGU for Christmas! I love it. Riding solo, I'm pretty sure the bike feels more "flickable" (not a word often associated with HD tourers, but one that describes the feeling of dropping 17 lbs of dead weight under the rider's butt).

Then, I had to buy a new charger for the Lithium. I don't like "tenders" because I once had a Deltran tender fry a Yuasa that was on months-long storage "untended by me." I decided to administer only a full charge, and then disconnect the device. And do that every week or so. Rather than just let the Tender have the battery to itself. I bought a new Optimate 0.8a LFP charger (around $50). This charger does a whole lot more than just "tend" the battery for weeks and months, though it will do that just fine as well.
