Simple, Effective, and Versatile
I’ve been using this charger for a bit now, and it's doing exactly what I needed it to. Switching between 6V and 12V is easy, and it works well with both my car battery and an old motorcycle battery I had lying around. I appreciate that it supports multiple battery types, including lithium and AGM, since I’ve got a mix in the garage.The unit feels solid and well-made, and it doesn’t get too hot while running. I also like that it's automatic—it switches to maintenance mode on its own, so I don’t have to worry about overcharging. It’s compact and stores easily when not in use.Overall, it’s been reliable and simple to use. Definitely a good investment if you want to keep your batteries topped off and ready to go.

Excellent Quality, Heavy Duty Battery Tender - Buy this knowing you'll be quite happy
Well if you know Battery Tender then you already know what this review will say. If you do not know this brand please read.The size is what you would expect from this item, there are smaller foot print battery tenders available but the charge rate does drop.This particular model work amazingly wellThe charge rate is exactly what one would hope for in a tender - it is not a "fast" charge as it is not meant to be; However, it does get the battery full quicklyThe indicator lights are bright and easy to read/understand at a quick glanceBattery Tender durability is excellent I have a few actually one is over 10 years old and going strong

A Must for Classic Car Owners
This worked like a champ. Not only did it charge up my car battery but kept it charged till I needed it. It’s a quality product built well and a great value. A must have for classic car owners who only drive once in a while.

Charge then maintains! No over charge.
Any vehicle that sits for a time needs one of these. They work well. Never fails. Easy to use. Cheaper ones don’t work like Battery tender. Cheaper one cook juice out of the battery. Rendering them useless. Only option then is replacing them.

Great set it and forget it maintainers
Why did you pick this product vs others?:Had 2 of older versions of these battery maintainers I bought at Costco about 10 years ago. One still works but some of the lights don'twork. These new versions are similar but have several updates. The alligator clips now are insulated better. The charge curve seems to be better also. Great set it and forget it maintainers.
