Like many people I grew up thinking bigger was always better, but that is not the case in battery chargers! The NOCO Genius G3500 battery charger is small in size but can charge many different types of batteries. I use one for charging ATV, lawn tractor, automobile, and farm tractor batteries. When I'm not using my ATV I leave the charger connected to it to keep the battery fully charged. The charger will stop charging when the battery is fully charged and will automatically go into 'maintain mode.' This is the best charger for the money and I highly recommend it.

After having trouble with a well known brand on board marine battery charger I decided to try this one. Works well with good indicator lights so you know what is going on. I'll see how it lasts long term. One of the best things is it's very compact size.

A little pricey, but a dandy little battery charger/maintainer, with desulfation function to boot. The only thing which would make it a better value is if they included a connection adapter needed to mate it with other SAE type battery charger/maintainer cord connections.

I tried an older model Noco 750 to save small batteries (scooters, generators, lawn tractors) that other (Deltran Battery Tender) "smart chargers" had let die way before their time. It brought all those back and they still live. This time the same thing happened with a battery in my Corvette. The Noco Genius5 brought it fully back to life and it is staying that way. GREAT product. I then also bought 4 more Noco Genius1 smart trickle chargers to replace the "old" products on other cars that I winter store. In fact when I replaced the "other" trickle chargers they were showing all green (fully charged) and the Noco's spent several hours on pulsing red and green getting the batteries to an actual full charge. I plan to pick up a Noco Genius10 in the spring also, I like great modern tools that work........ Kudos Noco ! Read full review

I bought the earlier model of this, the G3500 (3 amp), a few years ago and it works very well. I have it in a barn 800 miles away where it is keeping a 12V cranking battery for an outboard motor maintained for the winter. I bought this model, 5 amp, to charge and maintain a 12V deep cycle trolling motor battery. This charger is easy to use, very small and does what it is supposed to. If it is made as well as the G3500, it will work for many years.
