1.75-Amp 6V and 12V Smart Fully Automatic Battery Charger Maintainer, Trickle Charger, Battery Desulfator for Car, Lawn Mower, Motorcycle, Boat, Marine Lead Acid Batteries

This little charger is fantastic! It’s a 1.75A charger that out performs my larger old trickle charger. It’s a smart unit with an easy to read display. (One thing to note: it will specifically NOT work for LiFePO4 batteries. This will NOT do the charging profile required for ONLY those batteries, But it works VERY well for AGM and standard batteries.) I bought it to use the de-sulfate feature on some old UPS batteries, but they were too far gone. However, I’ve used it on my Harley battery as a regular charger and it’s been strong and reliable. It starts out as a regular charger, then shuts off when the battery is full, then automatically goes into trickle mode as it needs to. It’s got a great feature in that it displays what it’s doing. The display toggles back and forth showing the exact volts and amps it’s putting out as well as the graphical display of the battery filling up. It’s a “set up and leave it go” thing that will shut down when the battery doesn’t need it or it will turn back on when it’s needed. Recently my truck battery was too low to turn it over so I connected this charger. I like the voltmeter display. It showed 11.2v before I plugged it into the wall. Once plugged in, this unit displayed exactly what it was doing and had me up and fully charged over night. The next day I did notice that when I moved the cord at the connection, the screen went dark. I surmised that there are broken wires in the SAE plug. I contacted the seller asking for a new SAE plug to solder on, and they wrote back overnight that they are sending me an entire new unit! What great customer service! This is a great little charger that does all that I need backed by a company with great customer service!

I've got a car that I don't drive a lot and the battery won't stay charged. This works great for keeping the power topped off. Like how it's compact with instruction that are simple for my kids to understand. Plus this is a battery saver, there not cheap anymore.

Came Quickly and works as described.

The tender works good on a working battery. Background, my battery was at it's end life when I bought this unit. My previous tender stopped working two or three weeks prior to purchasing which caused my battery to unexpectedly not hold a charge or hold up for a jump. Initially after buying it seemed the unit was not registering my battery as advertised. After reaching out to the seller and explained the situation, I was getting ready to return the unit since it seemed faulty out of the box. After jump starting the car failed with a known good jump box, I had the battery tested and it was determined the battery was past it's expiration. Since replacing the battery, the unit register's the battery as expected and has been trickle charging without an issue since. It connects and plugs in quickly. Switching between modes is as easy as the press of the button and hadn't had an issue since the battery was replaced. I have been using this for several months and it seems to be holding up well to the elements. I still have yet to try it in cold weather but seems to be holding up well so gar with the weather.

So far all is good with it. It’s very nice for me he price especially that it offers 3 different settings. Very simple to use. I son has two and hadn’t had any negative feedback.
