Yup... I was the one that reported the shorted out, melted Battery Tender... Then I learned out about battery cell sulfation situation and upgraded to the Battery Minders as to clear this issue. I will never forget talking with Battery Tender support after finding the melted battery tender, they did replace it at no charge... But then called back a week later strongly urging me to return the defective unit but by then it was already bye-bye in the dumpster.. Having that type of defective product can cost them big $$ if a defective Battery Tender starts a fire.. Just my $0.02...

I use 2amp (schumaker I believe) unit on my Cummins (two batteries) and they are original to truck (built June 24, 2002!!) . . . and have other units on other cars . . .just monitor your chargers and batteries to ensure everything is ok. If you are going to go away for extend period of time, then unplug the unit for safety sake. . . one other thing for long battery life - if the caps can be taken off (even when it says "maintenance free"), take them off and ensure that you have fluid level topped up to bottom of cap well (you can see the change from flat level to "cupped' meniscus when level hits bottom of well), using distilled water. I truly am amazed at the batteries in my truck, almost 20 years !! Then again, I don't drive it in winter . . . most of the batteries in my cars are well over 10 years now, with no issues - thanks to battery maintainers. Just use smartly and safely . . .

I started using a BT on my Ninja at the advice of the dealer. Before a battery would last 2 years tops. The last one was still good at 5 years. I keep one on my race car when it sits too.

I work at a tech college. We store a number of training vehicles in a pole barn for extended periods of time. Got tired of the batts going dead so we put battery tenders(not sure of exact brand) on them. Fire inspector came through and said . Told us they get lots of calls regarding those and fire risk. We took them all off(had to). On my old muscle I just disconnect the batt( don't even take it out)and reconnect in the spring when I get it back out.Been doing that for many years and I'm in WI. Cars live in an uninsulated/unheated garage and -20f happens here....current batt is over 10 years old. On my newer toy I just fire it up every month or 2....hate disconnecting the batt on new stuff....computers and all.

The Battery Tender by Deltran is a good product. But if its an old classic with zero key off draw you should be able to let it sit for months as long as your put it away with a fully charged battery.

Northern Tool is already selling them at Black Friday price. https://www.northerntool.com/shop/tools/product_200332201_200332201

I too had been using the Battery Tenders for many years without any issues. But finding the shorted unit with the melted case was a wake-up call for me.... The Battery Tender is assembled with many internal components from China, and my basic question is why don't they design in an internal circuit breaker in case the unit shorts out. This will shut down the unit as to prevent a possible fire.. Just my $0.02..

What kind of battery? AGM, no, you have to have a special tender. I’ve been using Battery Tender Jrs on agms for years. They cycle correctly (go through the charge mode then go into float) just fine.
