🔋 YONHAN 5 Amp 6V/12V Car Battery Charger Maintainer - Trickle Charger for Car, Boat, Motorcycle, Lawn Mower, Marine Sealed Lead Acid Battery and More Review

I paid for two of these because I trusted the reviews. They work for about a week and then stop charging completely (both) as you can see in my photos it says "FULL" BUT my multimeter reads well under 8 volts when the charger is connected. (12 volts is needed to start your car) ---- This happened with both chargers I received. Buyer Warning.

I parked in my garage and accidentally left the trunk open overnight and the light drained my battery. The remote didn't even open the door, so very little power. I plugged it into my car and into an outlet in the garage and within hours my battery was fully charged! So thank you! Saved me money and will be great to have on hand for future emergencies. The only thing I don't like is that the plastic covers on the clips come off easily, but it doesn't affect performance. Goodbye!

Pulse charge has been running for 7 hours but there is no capacity or charging results. Can't comment on how well this works yet, but I'm using an extension cord with a truck battery. The photos show the charger connected in this way, but the booklet that came with it tells you very little. After another 9 hours I will check again and switch to pulse charge mode if it doesn't switch itself. I also noticed that there is no labeling on my device and there is a Russian font in the instructions. I…

The thing definitely burned after the first use. The heart crackles, then the smell of burning and the fan stops working. Now the screen flickers and I don't dare use it without setting it on fire. I would not recommend this unit as it does NOT have surge protection despite what it says on the box (assuming it did after I connected the cables correctly and followed the instructions). This thing was cheap and I should have known better as the performance matched the price.

I haven't been able to charge this battery to "Full Charge" for 3 days. I tried following the instructions. I didn't pay attention to this when purchasing this item. This item is not eligible for free returns or refunds. It costs me $7.42 if I rent it from the UPS store. It costs me $13.42 to receive UPS at my home. 99% of other sellers FREE. It was always FREE from Revain when I was paying $132 a year in membership fees. Please be careful. There is no guaranteed return for this item. You will…

Bought to charge my car battery because it was too low to jump my truck. When I plugged it in it told me the battery was full so I used pulse mode to recover the battery and then ran actual charge mode and it worked amazing! Out of curiosity I hooked it up to my super old battery which has been dead for 2 years and is lying on the garage floor. I ran the pulse/repair a few times over a couple of nights, then ran the actual charge, threw it in the car and it immediately caught fire. Checked the…

This small charger is good for charging AGM batteries with pulse function which can restore their capacity. Works great with my 8Ah batteries and also brought back a 22Ah battery that had lost most of its charge after being idle for over a year. I wouldn't charge with a normal charger. Using pulse charge mode on this charger for about a week, the voltage gradually approached and is now holding a charge. Just unplug the charger and it will display the battery voltage and the temperature of the…
