I have 4 Battery Tender Jrs. One on my HC, one on my moho chassis batt, one on my Jeep and one one my wife’s quad. They work great.

Pretty sure that's what I got on mine. Had it for 5 winters now over 2 cars. No issues.

I have used this one for 5 years. Has a lot of features. Only one recommended for AGM batteries. Screen Shot 2019-12-01 at 2.29.58 PM.png Screen Shot 2019-12-01 at 2.29.58 PM.png

-Another vouch for the Deltran battery tender. I have a dual one that I keep both my Redeye and Camaro on all winter. I've had it for about ten years now with no issues at all.

For a acid lead battery like the stock one - I just used a Harbor Freight one for $6 - plenty good.
For my lithium battery I bought the CTEC like in above ^^^Octanewide pic. , it was about $70.

X3 - I have battery tenders for my quads - kept my quad battery good for over 5 years. Quite a feat for that...
For my Barracuda I have an Optima and an Optima charger/tender, not really sold on the Optima - I am on my third one, but it doesnt get used a lot...

The Ctek MUS 4.3 is superior unit, a little more features then the 70$ unit. it has a Desulphation mode which is excellent for lead acid batteries on long term storage.

I have used the Battery Minder 1510 and 12177 for several batteries in stored vehicles, tractors, etc. My dad is an Electrical Engineer and brought this minder to my attention when I was going to purchase a battery tender. The battery minder has an algorithm which desulfates the battery as it keeps it charged and I have had a mopar reproduction battery in my Road Runner for 7 years and it is still strong. Would use nothing else. You can hook up to 4 batteries to one unit with a SAE splitter and this works well too. Also works with AGM and has kept my Harley battery alive for 4 years so far.
