2 Pack Motorcycle Battery Charger 12V, 1.1Amp Trickle Charger and Maintainer - Smart Automatic Float Charger for Cruiser Sport Bike ATV Scooter Dirt Bike Lawn Mower, LiFePO4 Lead Acid AGM Gel

Use on our 300kw generator. Very solid & reliable. They come with the harness kit that has ring terminals to connect to your battery post clamps - ring terminals wired thru a 3amp fuse with a polarized plug on the end. Since our generator is stationary, these are a permanent install. On you vehicles, the device can be permanently or temporarily mounted so all you need is an extension cord to power it. Nice that they sell a 2 pack. Our generator uses 2 batteries (24v system) and we have each battery being maintained by its own device. We have been through half a dozen of the 24v battery maintainers in the last few years - for some reason they don't live long. We leave ours powered on constantly. Our batteries are always ready! Every month when we do our PM & exercise run of the motor, the batteries are fully charged. The individual chargers never got hot or operated in an erratic way. We also own a second pack of these for our UTVs. Ditto on performance as mentioned above. The UTVs use those AGM batteries and all is well - no overcharging. Obviously these charger/maintainers work with regular flooded lead acid batteries. So if own equipment that sees seasonal or standby use, get a set of these devices. Awesome price point for a pair of them. They do not dissapoint. Two thumbs up!

Works great, fast delevery

These little chargers are amazing I have 8 of them for all the equipment I leave behind during winter. They are not jumpers just chargers. Great product.

Easy to set-up, use and runs effortlessly and continuously afterwards.

Working great! Put one on my motorcycle and one on a car in storage, both batteries probably need replaced and we're a bit weak but are cranking over like new when I checked last.

I use this to keep my batteries charged on my boat. It is nice to know that the battery are at 100% every time you want to use it. I clip the red on the positive terminal and black on the negative terminal on to the batteries and plug them in and led lights indicate the level of charge. It also has device that you can attached to your battery so that you don't even need to do the clips. I will be doing this soon to save little time.

These are so unbelievably useful. I no longer have to mess around for an hour charging my loader or tractor. I'm a dummy for not figuring that out a long time ago, but I'm glad that I use them now. They are cheap enough that I keep a spare in case one breaks. The wires are a bit flimsy, but it really doesn't matter. It's cheaper and faster to just swap in the new one than to fiddle around soldering it if a wire pulls off. If you've had to delay doing work while your tractor sits on a charger, buy these and never do that again. So worth it.

Been using for around a year now and works perfectly. Most importantly, the plug is standard wired so you can plug it into any motorcycle that has a factory quick disconnect plug, and it will work correctly. We have a Harley Davidson in this uses that factory plug with no issues. I purchased another brand that actually had the wiring backwards, which is dangerous. This is a great cost-effective solution to keep your batteries maintained. I highly recommend.

Très satisfait!!! Mes batteries de vtt étaient en fin de vie il y a deux ans. Ces chargeurs les ont ramenés à la vie depuis que je les laisses connecter tout l’hiver au lieu d’entrer les batteries à l’intérieur. Bien plus simple et ca fait la job à merveille! Pas d’explication concrete mais ca marche!

Très satisfait.

Seems slow but I guess they are not a big charger. So far so good

I bought these to keep the batteries on my SeaDoo's charged over the winter. Easy to install. Keeping the batteries topped up. Would recommend.

Très compact facile installer une fois installé j ai vérifié avec un multimètre le voltage montais bien .
