Car Battery Charger and Maintainer 3.8A 6V 12V Intelligent Household Automotive Charger with 8 Modes for 12V LiFePO4 / Lead-acid Battery of Wet/GEL/MF/CA/EFB/AGM/VRLA

Had this for several months now and I have to say for the price, the quality is superb, it maintains the battery extremely well and has all the modes you would need. I've used it to trickle charge and fully charge, as well as recondition the battery and it has performed flawlessly every time (and I've not felt it get hot, in fact it's normally not even warm). The main unit is a little sizeable, but can still be tucked away inside the engine bay should you need to (rather than trailing outside). Compared to far more expensive alternatives which I've had in the past, this is superb value for money.

I needed a battery charger suitable to recharge the flat battery in my wife's Smart Car, which has MHD (stop/start) fitted. This seemed to fit the bill, got good reviews and I was very pleased at how easy and foolproof it was to set up and use; the hardest part was accessing the battery, which in a Smart is under the carpet in the footwell. The instructions are in good, clear English, which always helps. After an overnight charge the car started at the first turn of the key, confirming the green '100% charged' LED. I also liked the inclusion of a plug-in connector, so I won't have to get at the battery again to keep it topped up when the car isn't being used much. I expect motorhome or classic car, etc. owners will find this feature useful for the same reason. 5*****'s!

Charger is of high quality, and works well, but will *not* trickle charge lithium batteries. Once the lithium battery is fully charged it will stop charging, and despite still being plugged in and appearing to be fully charged, the battery will actually be slowly draining. Every week or two I have to pop in to the garage and restart the charger to top the battery back up.

I own alot of plant & machinary that quite often dont get used so need to keep on top of battery maintenance. I own 4 of these chargers purchased over the past year or so. All except 1 work great, I contacted the seller and new charger was sent straight out and been problem free. I like these chargers as they are very cheap for what they are. They are not as water resistant as stated however I use some outside but covered over without issue. They also come with crocodile clips to temporerily attach to a battery or a extra cable that can be perminently fixed to the battery with a quick release connector. I use on big truck batteries as well as tiny kids toys batteries without issue. Very easy to use however need to spend 2 mins reading the instrutions to understand the different modes. Every home garage should have 1.

Had to take battery out of Honda Civic 2018 because after I had been away for almost 2 weeks, upon on my return I found I couldn't start the car, engine turned like 3 times then nothing happened. Tried a jump kit and engine turned 7-8 times then drained my jump kit from full to empty after trying 3 times. So I placed an order for this charger, next day delivery. I'm truly surprised how well this has worked up to now. So when the charger arrived I read the instructions, they could have been clearer regarding EFB batteries, had to do some research to find that AGM and EFB batteries are charged the same way. At around 3pm I put the battery on charge with 12v AGM setting selected and at 8:30pm the battery is almost fully charged with the 100% green light flashing (not quite there yet) :) the battery when initially connected was flat the 25% light was flashing for a couple of hours indicating the the charge left in the battery was less than 25% so im pretty confident that this product can charge an almost if not fully dead battery. Overall great product, good value for money. Fingers crossed everything is good when I finally go place the battery back in my car

Good price, easy to use and it works, no complaints. Used to charge my fiancees car to 100% that hasn’t been getting out as much as it used to. Confirmed the readings given by the charger with a multimeter and again after charging, they matched up perfectly and the battery read 12.72v once the charger indicated that it was charged to 100%. Would recommend to others.

Instructions not to clear. Here is my version; Connect red clip to the plus terminal, black clip to minus terminal, plug in and switch on the power, stand by button goes to green, for normal car battery press mode button once, first light in the box goes red and in the top row 25% goes to red, just leave the charger to get on with it... after a while the 50% button will flash orange, after a time it go steady orange, after a while it will go 75% then on to 100% steady green when battery full( my battery took about 5 hours, different batteries time will differ no doubt. Its as simple as that. I then did the repair option, I think this best done when battery has some charge in it, I know that sounds Irish, anyway, starting with power off, switch the power on, hold mode button for 3 secs, touch button mode once more to move to repair, green light flashes, mine took about 4 hours the changed to solid green. Job done. I like this machine does a good job (do not start engine when attached) when removing, switch of power take black clip off first. Hope this makes sense.

Tried it a few times using it even holding conversations about it with the seller but in the end I just didn’t think this product worked for me. Plugged it in as instructed and it started charging going through all the stages. It then reached 100% and all % LEDs solidly lit so to me this meant the battery was charged. Well, the car didn’t think that was the case, it kept telling me the battery needed charging. After speaking with the seller I was told that I had to keep it on the battery for about another 10 hours! What? Why was the charger telling me it was charged? Something didn’t make sense to me. The instructions aren’t clear about this at all. I ended up asking a friend to test his charger and see there it kept charging the battery when this one told me that it was charged. Not good at all. Went back for a refund. Thank goodness Amazon is my friend.
