I have probably six or seven batter tenders on the farm from everything to our vehicles, tractor, and various other mowers, etc. They are all Schumacher and run around $25 on Amazon

They all work perfectly.

CTEK for me. Had to keep my C5 Z06 plugged in when I wouldn't drive it for more than a week. Damn thing had a draw somewhere and I was too lazy to look for it.

Battery Tenders.

I have a NOCO Genius smart battery tender that I use on my motorcycle (fair weather rider). Highly recommend.

Years ago I went with the ‘Optima’ battery tender route. I now have the 3 & 4, use them on multiple vehichels & powersport batteries.

Just another to consider, the Optima 4 or newer. Some reading. The Ctek does well in most reviews.

CTEK will do it all.
Battery tender, standard charge, sulfated battery, rapid charge, optima/AGM, etc.
They make some very nice accessory connectors too.

60.oo from Wal-Mart will last year's.
They are replaceable nowadays.

I've run only the Battery Tender as do many of the guys I ride with, the Harley Davidson branded unit is a BT.

You can get a connection that you put on the battery and the end where you can access it without opening the hood and connect up when you park.

BT has single charge and multiport smart charge units.

I think some of us are using Battery Tender as a brand name (manufactured by Deltran), and some others are using it in a generic manner as another term for a battery maintainer. My earlier recommendation referred to the Deltran Battery Tender.

To be clear, the standard Battery Tenders and the clones are not chargers. they will only maintain a battery to peak.

CTEK is a good brand but if you want one better consider getting one of the NOCO Genius models.

I use the NOCO Genius G7200 on vehicles with expensive batteries and it "exercises" the batteries to maintain them in their best possible shape.

A G3500 might work for your application and be a few dollars cheaper...

I don't know why you would say that, its not accurate IMO. For sure the deltran ones I use and recommend above have limited current capacity (mine are 5a and some of the smaller ones are less) so its not like some larger devices (I have one large one for emergencies and its 225a) but given enough time relative to the capacity of the battery they will charge any battery. I have used them to charge very large 8d batteries from full discharge. Current is current, they will apply it till the battery is charged and then float.

Battery Minder is the brand I’ve used for several years. Two different units keep my two cars and tractor charged and desulfated during the winter. I bought them when they were advertised mostly for aircraft and figured why not, should be overkill for my garage. Desulfating, temperature compensation, and a ton of accessories made me happy.

I use the Battery Minder for maintaining my AGM batteries. They have a special AGM model, with a desulfating feature. I use the Deltran Battery Tenders for my regular flooded batteries.
