3.5A/1A 12V/6V Automotive Trickle Battery Charger Maintainer for Cars Motorcycles RVs TVs Boat for Normal Lead Acid GEL AGM SEALED WET or 12V-Lithium(LiFePO4) Batteries, With IP65 Waterproof

Works on so many different battery types, no issue as of yet, easy to use.

Works great. Very functional. We were able to use it for our ATV. The lawnmower and the car battery.

I just discovered that this product has not been working. I had it hooked up to my motorcycle to be a trickle charger when it's not regularly used and despite the selected voltage light being on the other lights (charging, fault, etc...) do not come on to indicate that it's working which I just discovered it does not. The real crappy thing is that upon discovering that this product does not work I'm 2 DAYS PAST THE RETURN WINDOW.

Seems to be a great little charger, it has a very loud fault beep which could be bad for some people but it clearly indicated it wasn't working and was not ignorable. I remove one star because the lights are not labelled for voltage, 12v is first then 6v, which is clearly in the instructions but should be on the label, nothing a sharpie won't cure. For the money I like it, will buy again if it's available later.

This is a very nice charger. The pig tail that is attached to the battery makescharger very simple. The charge time is very reasonable

Not that great but ok

Detects fill battery, adjustable to battery voltage and has a chip to monitor battery while charging.

I ordered 4 of these chargers to charge the batteries and keep the batteries charged on 2 boats and 2 jet skis. Two of them didn't work properly and the other two charged the batteries but wouldn't switch to the 'trickle charge' mode. I ended up unplugging them and returning the ones that didn't work. I would not recommend this product because it doesn't work as advertized.
