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!

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.

When I ordered these I was not sure they would charge the car and large tractor batters I put in storage every year. However I am very impressed with the low charge rate (1000ma which is 1 amp) how well they charged the batteries and with the LED readouts you know if the battery is good and whether it is 50% or below or 50% or above. The largest battery started at 50% or below and although it took about 2 days it did charge the battery. Usual I just use a larger charger, this time I wanted to see if it would actually charge the battery. I will be using them as battery maintainers.

Seemed to be working as described on the mower... after parking and plugging it in, it would seem to go through a cycle of testing and charging for 30-60 seconds and then settle into a monitoring condition. However, one day I noticed there were NO lights so I checked the power to it but it never lit up again... I checked for output in case it was an LED problem but it was completely non-functional. The good news is that the second one (which was plugged in next to that one) is still being used for the motorcycle and it seems to be working fine... so the purchase was only half bad.

These work great to keep my vehicles and mower batteries charged.

Works great, fast delevery

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.

Nice

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!

Una forma sencilla y económica de mantener la carga de la batería, sin importar el tiempo en que no se use el automóvil.

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

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.
