LVYUAN 2/10/25 Amp Car Battery Charger,12V Fully Automatic Smart Battery Maintainer with Engine Start, Trickle Charger, Auto Desulfator, Battery Repair, for All Lead-Acid

I had my truck battery, a nationally known, high quality brand, only 8 months old, go dead on me. I mean DEAD. Like a rock dead. My old analog charger that I'd used for a very long time simply reset over and over when I tried to use it to charge the battery. It was Labor Day weekend so there wasn't much I could do taking it somewhere to be tested so I ordered this "smart" battery charger and it was delivered the next day. I followed the instructions and set it to run the 24 hr Repair Cycle (if you ever do this, make sure that the battery is disconnected from the car to avoid damaging your electronics). At the end of the cycle the charger did an auto-check of the battery and made sure that it was fully charged. I took it down to the Battery manufacturer's distribution center(very luckily there is one in the next town over) had them test it. Holy cow, it tested perfectly good! /yay. I installed it back onto my truck and it's behaving as if nothing ever happened. I love this charger!It's nice and compact and has a cooling fan that automatically activates if the charger gets too warm. The case is metal, not plastic, so that will serve as a heat-sync. It will auto-sense what kind of battery you have, but you do have manual control of certain settings should you wish to try a particular charging sequence. The charger will choose the appropriate amperage for the job, too. The display is very easy to read and will keep you informed of the charging as it progresses.I have lots of different types of batteries and as this charger will work with all type of lead-acid batteries, including GEL and ADM, it will pretty much cover all of my bases.Definitely recommended.

Purchased this as a battery maintainer in my RV and have had no battery problems. It maintains 13.8 vdc and the fan is silent. Nice product, would recommend

Works as it should. I’ve used it several times without any issues.

The charger stopped powering up after 14 months. When I contacted the company they sent a new replacement even though the warranty was up after 12 months. They were very cooperative.

I couldn't get the charger to stop blinking, I put in 10a but it would go back to 0. Then I tried turning the charger off but it wouldn't turn off, so I had to unplug it. So Basically it didn't work.

Three amp settings, slow trickle charge, regular, and fast 25 amps.

Excellent buy awesome charger

I've tested it on several LI and lead batteries. So far so good.
