SolaMr 12V 24V Heavy Duty Car Battery Charger, 0-20A Trickle Charger for Car Truck Motorcycle Lawn Mower Battery AGM, Metal Case Smart Battery Maintainer with Automatic Shutoffs, Repair, Winter Mode

This is the best and fastest charger I have owned,it literally brought a car battery with less than 1.0 volts back to fully charged and it is still working at full capacity ,I am soooo happy with my purchase.

Haven’t needed it for my car yet so I haven’t used it but I feel safer knowing I have it. It’s pretty heavy and bulky but makes me feel better about it working.

This thing I wouldn't say is large, but it's not small either. Maybe about the size of a small desktop computer case. It's got two battery cables built in to the back of it with a full LCD Readout on the front and a series of modifications and configurations that you can set as needed for whatever battery you're needing to charge. The build quality is fantastic/professional and the charging speed is essentially what you tell it you want. It's fairly heavy, fully functional, and the information guide that it comes with WILL BE NEEDED unless you've used these before and know what you're doing.

This car battery charger is wonderful. It has a nice metal case on it with a sturdy handle, and is very easy to use.I had a trailer battery which was a deep cycle that stopped taking a charge. I tried charging with three different batteries as well as a trickle charger and it didn't work well, but running it on the restore function did get it up and running again.I'm not sure if I could attribute that to this battery charger or the fact that I tried a bunch of other ones before this but I'm pretty happy that it worked.The one thing about this is that using it as a bench top charger and inside, The lights on the display is easy to read but if you bring it outside it's a bit difficult to see.Other than that does a good job doing what it's made for which is charging batteries.

It is a good quality heavy duty charger and a great option for battery Maintenance. Very easy to use it. It has clear LED screen for charging status. I like the features that the charger has. It is very fast charging. It automatically switches to a maintenance mode once the battery is fully charged. Overall it is a great value for the price. It is the best charger I got so far.

The first thing you notice about this charger is the size. It is big and it is HEAVY. The case is all metal and it’s much larger in every dimension than the other battery charger/maintainers I own. I don’t know how that translates into noticeable differences in performance between chargers.I like the length and heft of all the cords including the power cord and the cords that connect to the battery. They seem to be a heavier gauge than my other chargers and they are longer too. That makes connecting this charger much easier. Right now I have the charger on a rolling cart because of its size. It’s so large you can’t easily set it on a car fender but the cables are long enough that I can roll the cart up close to my mower and still easily connect to the battery. The same will be true with my tractor. The clamps at the end of the cords also seem to be high quality. They are almost completely encased in plastic so there is little risk of having an accidental short circuit from the clamps touching something they shouldn’t. There are also protective features like a fuse in the back and overload protection.The most important thing I like about this is how intuitive it is to use. I have other chargers that are difficult to use without consulting the owner’s manual. This charger just seems more straight forward to me. There are a number of choices you make depending on the battery you are charging, existing charge in the battery, how fast you want to charge, and even time of year (there’s a “winter” setting). That provides a lot of versatility and flexibility but the nice thing is that the choices are clear and easy to make.I used this once so far to charge a mower battery. Before I connected the charger, I tested the battery and found that it had 61% strength of charge, 65% life, current 276 A (CCA), and 12.37 volts – it definitely needed charging. It took a little over 4 hours to fully charge but when the charger said the battery was at 100% charge, my tester indicated that the battery was at too high a voltage to test. When charging the battery, I had the charger set to “Maintain” and on “Winter” setting so I don’t know if that had anything to do with it or not. According to the manual, when set to “Maintain”, the charger is always providing a small charge to the battery (a trickle charge). Next time I charge the battery I will try the “Auto Off” mode and see if that makes a difference. Also, I don’t know the temperature range for the Winter setting. When I charged the battery, the temperature was in the 50’s. I don’t know if that is considered Winter or not. Anyway, I let the battery sit for two days then rechecked it. At that time strength of charge was 100%, life was 91%, current 326 A, and voltage was 12.86. So the battery condition was definitely improved I’m just uncertain what happened when it appeared to be overcharged, especially given that this is supposed to have overload protection.At this point, I’m pretty happy with this charger. I will definitely be paying attention to the battery state immediately after charging and will try some of the other settings.

I like to drive my truck in the colder time of year so my normal vehicle sits in the carport all through the colder time of year. This has made the battery channel. Presently with this battery charger I can keep my vehicle's battery charged until the days off are finished. This charger offers two charging modes: quick charging and stream charging, and naturally identifies whether the battery is 12V or 24V. It changes the current to meet the charging needs of various batteries, making it simple to utilize so I want to fitting and begin.

Tried it on a very low battery. I checked back in a bit over an hour and it was fully charged and auto-switched to trickle charge. So far, I'm very pleased with it.
