Jake: My charger worked great until it didn’t, seemed like a fluke usually a great product. NOCO stood behind their product and shipped me a replacement ASAP. 3 stars for product 5 stars for service.

UPDATE
FANTASTIC SERVICE. Would buy again.

Jake: I installed this charger on my Lund boat to charge 2 maintenance free electric motor batteries and 1 main boat battery (with a 12 foot extension spliced to the rear). They charge 4 amp per bank and is a slower charge, but remember you're plugging into a 15 amp max rated 14-2 standard plug and 15 amp breaker. It works just fine overnight. I've only had it a few weeks, but so far happy with the purchase. Hopefully it's durable and lasts a long time. The screws that come with the unit had a very hard time screwing into harder wood. It would have been nice to include a 4-pack of different length screws for different applications. Screws that come with the unit are 1.25".

Gary M.Gary M.: I love this thing. It will charge three batteries super fast. We usually sit out on the lake with music going on our two additional batteries. All I have to do when done is throw an extension cord in boat and plug it in to the extension I also boat which I mounted drilling a 2” hole in the seat area. It works to perfection and we have had zero issues with it. It is water proof and nothing has come close to messing it up.

Chris Lett: This battery tender is extremely nice! I've owned many cheap tenders before in the past and the quality that went into this is worth the money. Read my notes and if you're aware of these 2 factors then you will be in for zero surprises.

I purchased 3 mini jumper-cable style ends to make swapping my batteries in and out a breeze. "SEE LINK BELOW NOTES". If you do not have available wire around then you will need to purchase wire to fit a replica of the setup I just described.

Notes:

1. If your battery is dead, you will need to jump-start the dead battery before this tender will do its job.
2. This does not come with jumper-cable style connectors so if you have a battery that has post then you will need connectors to mate with the post or mini jumper-cable attachments (Aligator Clips) that will fit your battery...

tkgibson: Absolutely love these NOCO Genius chargers and are my go to battery charger. These work so well and for many uses. I have 6 in use in different vehicles and garages. I have a 2 place charger to keep ATVs charged between uses and this has prolonged the battery life greatly. This 3 place charger is for summer water toys to consolidate space and maximize battery life. I have added single NOCO chargers to vehicles to keep batteries charged and ready. Most are inside, but a couple are under the hood of the vehicles and I ran the power cord outside to plug in without opening the hood. One is on my work truck to keep it charged during cold nights. Highly recommend these as I have never had issues and well built units!!
