Its combination of versatility, ease of use, and intelligent charging features makes it a worthwhile investment for maintaining the health and longevity of your vehicle batteries.

This charger works! It remembers what setting for battery type, so when you plug same battery in again you don't have to change settings. Unbolt the battery clips and it leaves you with ring terminals that you can leave attached to your battery. Both ends of plugs have a cover to keep dirt and debris out of plugs when not used. This also has an automatic battery conditioner that detects when its needed. Simple easy to read indicator lights to see condition of battery charge. This is my second unit, was so happy with my first.. High quality product, for a reasonable price. Side notethey sell an adapter plug that connects to plug left behind on battery. It enables a usb cord to be used to charge cellphones ect. This is perfect for my motorcycle without a charging port.

I've always used Battery Tender in the past. After a lot of online research I decided to give Noco a try based on the additional features it has over Battery Tender. I've been using it for a little over a week now and it's been great at maintaining and charging my 2 motorcycle batteries. My only complaint is the proprietary charging cables. Had to fork out and additional $35 for 2 of the standard adapters. No big deal... Just an inconvenience. Both of my motorcycle came with the standard charging cable pre installed from factory.

Why did you pick this product vs others?:Works great, it even came with mounting screws

Great chargers with all the included accessories. This is my second one after 5 years. (first one wouldn't always recognize the battery on the left bank)I have the same batteries in two new jet ski's I bought 5 years ago that have zero issues or need of replacement far and beyond the recommended 3 year lifespan.These devices repair and keep the battery perfect. I have them directly connected to the battery and just set and forget.

I love noco products I have jump start,battery chargers,noco battery’s LP30 LP 20..only thing was missing in this unit is motorbike Conection,this unit comes with 2 clamps.over all very well made,easy to use

Works Great good battery maintainer

I've used a of battery chargers/tenders over the years, and this is the best by far for battery maintenance. Really love having dual outputs. The cords and connectors are easy to use and it's nice to have the extension for a longer reach. The auto-detect feature for battery type, lead acid, AGM, Lithium, 12V or 6V is awesome. There's also an override feature by holding the power button down for 5 seconds that allows you to charge a battery that's less than 1V. The unit is solidly built, looks great, easy to read the status, even from across the room if you mount it on a wall. I bought two of these to keep my summer equipment charged all winter. The packaging is done so well it looks like something that came from Apple.
