Looks like the thermal sensor is inside the box, if that affects you.

I've got 4 of these on mowers, ATVs, and a truck that sits for prolonged periods to keep the batteries charge. Even use it to recharge depleted batteries from a solar setup. Works well to maintain batteries over long periods but don't expect it to bring back a fully drained battery.

I bought this about 5 years ago to keep a car battery I wasn't using often alive. Worked great. My only complaint is that I wish the battery lead wires were twice as long. While connecting it to a battery still in the car it's a little too short to reach from any good spot for me, and the unit was left dangling. It worked, but I ended up rigging something for the unit to rest on because I'm not a fan of things hanging from their wires

not really meant for charging but for keeping batteries charged. what is your solar setup like ? i store motorcycles and a jetski in a container and there's no power near it.....

no SAE connector on a 40 dollar device is a BIG fail.

It's a $24 device. Ok now?

Still a fail. You can get a battery maintainer for less than that and it actually comes with an SAE connector. Just as good. I've used many over the years. Got boxes of them.

Mostly agree, not that SAE is a great connector but it is the standard. And not sure why dollar amount matters, they're pennies each in bulk so just gimmee so I can hard wire to a few batteries and bounce from trickle to trickle.

buyer beware: do NOT buy the one "used" unit thats available on Amazon right now. it was likely mine. I purchased it used-like new, when I received it, one of the prongs that goes into the wall was broken off. I returned it same day, and see that there's now a new Used - like new available for sale again. this is probably the same unit.

I had one of these that just flat out died a few weeks ago. Had used it off and on a handful of times over the last several years, but decided to leave it on my riding mower full-time to keep the battery topped off. I came out a week or so later and it was totally DOA. No lights, no response to button presses - just gone.

I have no clue why it died, but prior to this, I had a cheap $20 Shumacher 3A charger/maintainer on that same battery for over five years with no issues. Not sure what all can go wrong with something like this, but it's completely sealed and unserviceable, so I guess it'll just have to toss it.

Great tool for maintaining or reviving batteries. It brought a 2-year-old agm car battery back to life after it sat for four months with a slow drain we didn't know about. Took four days to recharge, but we were willing to wait. Battery is now solid and cranks perfectly in single-digit weather after weeks without use. Would definitely buy again, and at this price it's a no-brainer.

Would love a recommendation for a good-value (not necessarily cheap) high-quality charger, ideally 10+ amps.
I could do the research but hoping someone in-the-know can save me time, there's so many options. The NOCO's are too often promoted on here (with very mixed reviews) for me to want to buy this. I've had very good luck switching to obscure brands for many of my tools, sadly U.S. brands are hardly a guarantee of quality these days

10+ ???
What for ? These are battery maintainers and not meant for charging.
The biggest I have is a 4amp maintainer (dewalt branded) that I have on a large backhoe that has 2 giant batteries. It gets hooked up as soon its parked. Batteries are lasting forever this way.
