2-Pack Smart Fully Automatic 6V 12V Battery Charger Maintainer for Car, Marine, Motorcycle, Lawn Mower

A simple solution for anyone that has a deep cell battery and lives north of the mason Dixon. These chargers were great. They’re simple, plug-in and go nothing to think about after that. used them between January and April this year. When I put the batteries back into the RV two days ago, they were fully charged and everything worked great!

I am very hesitant about many products, but I took a chance on this. I was very surprised how well these worked on our jet skis that I will be buying additional for other equipment. It maintains charge very well and provides battery information, so you know it is not being overcharged. Just a great product for the price.

I love the compact size and functionality. This item is easy to use and keeps my bike battery charged I pretty well.

Very good product. Works perfectly. Trickle charge (maintainer) is great. It charges to full charge, then the charge turns off. When voltage drops the trickle charge starts back up again. Basically, plug and forget. The only thing I don't like is the product and support is from China. I decided to keep it because I was not able to find one not made in China.

Work as advertised. Can’t beat them for the price. Love that you can see charge volts and amps on the screen

I was searching for a battery, tender for my bobcat, when I found this product on Amazon. The price point made it reasonable, because I actually needed two, one for the bobcat and one for a scooter. It comes with the adapters needed for both, it has a self regulating on off with a digital readout. That makes it very easy. If you need a battery, tender, this one does work very well. I've had it on both the scooter and the bobcat for a month now with no issues at all. Great value highly recommend. Not sure why Amazon asks the question if this is an age appropriate toy, it is definitely not a toy. This is a useful tool for your garage.

Great little charger. I bought this specifically to trickle charge the battery on my portable generator. I haven’t set that up yet, but I did get a chance to use it the other day when one of my cars needed a charge after sitting all winter without a tender, and when I pulled the lawn mower out. It worked great.If you have a 12v battery that is discharged too much it will think it’s a 6v battery and go into 6v charging mode. It’s not in the manual but you can get around this by holding the mode button for several seconds while in charge mode, it will switch to 12v! I found this out when messing around with it trying to charge my lawn mower battery that had discharged down to 4.5v.Edit: now I feel silly because I see force mode is in the product description here.

Works nicely. These are trickle chargers, meant for battery maintenance but they will charge a discharged battery, albeit slowly. I have one on a car we don't use often and one on my lawn tractor for the winter. When I first connected it, It showed the car only had a 25% charge but after being connected overnight, car was up to 100% and has been there ever since. Lawn tractor charged up more quickly and we'll see how well it starts come spring. Very happy with these for now.
