Battery Tender Power plus 3 Amp Charger

This battery tender works well on my marine grade battery for my pop-up trailer keeps the battery topped off without much concern for safety while being left plugged in for long periods of time in my garage. The auto switch from charger to maintainer is dependable and appreciated.The interface is simple easy to use and is able to be switched between 6V and 12 V If required. I would suggest this product for anyone looking for a three amp battery tender

Edited My truck battery was frozen, dead, and this couldn't detect it. I jump-started the truck, took it for a short drive, then hooked it up again. It detected the battery and charged it in a day. :) UPDATE :( Today I went to hook it up to the truck and got a spark when I plugged it in, the wire on the ac cord has stripped where it comes out of the unit. Fortunately it was my last day to return it. I also have the 1.25 amp model which is 10 years old, a better design, still works great, and is conveniently unavailable right now. I wanted a larger one for the truck. I returned it. Have to think now.

el equipo fue recibido antes del plazo prometido, todo en orden, éste fin de semana procederé a la instalación y veremos los resultados

This is a battery tender and not a trickle charger. It is designed as something you can use to recharge your battery pretty quickly then put it your car battery for extended periods so that it won’t go dead. Unlike a trickle charger, it won’t try and keep charging your battery once it’s fully charged. If that’s what you need, then this is a great one. It’s super simple to use. You can even hard-wire it to the battery and leave a tail for plugging it in. I bought this to maintain voltage on the 12V system on my EV. Though our EV is our main car, we don’t drive it much, we seldom drive it far, and sometimes (especially when we go on driving vacations in our other car), it’ll sit for a week or two at a time. EVs have small batteries and a bunch of always-on electronics that just don’t sit well with that. This keeps the car ready in all those long sit conditions. I wish I could just leave my EV plugged into the charger and let it figure out how to keep the battery charged. But as the poem goes, if wishes were horses… well that ain’t the situation. This is. Also, I think that we’ll be using it on our gas car as we’re driving that less and less and may hit that need. This charger solves the angst of

It just works. I have a newer Hybrid vehicle. Generally we won't drive it much in the winter, and lo behold the 12V battery was at ~3V or so after about 10 days outside in the cold. So we battery pack boosted it and drove around. Got it back up to charge. Purchased a Noco5 and it was worthless. Just read it was at 25% no matter what mode it was in. Checked voltage at 12.1V and it still read 25%. Sure enough after a week or so the battery was running to about 6V and I sent the Noco5 back. Enter this little gem. Keeps the 12V maintained, granted it's only been a couple of days now, but put it on at 11.4V and read it again after taking it off today at 12.2V. I will update after winter to see how this holds up but at the moment very pleased that it's as simple as plugging it in.
