  • I made a mistake
Bought a new boat with house & starter batteries. Thought it would be great if I bought a two bank charger. Turns out the boat has an electronic battery isolator that when the starter battery is being charged it connects the house battery so it also charges. So I didn’t need a two bank charger, so I sent this one back and ordered a single bank charger. Just reminds me I need to get the full skinny before I jump into something. ... show more

  • Amazing battery charger
What can i say. Wow, I never knew what i was missing. I bought this to charge both my batteries on my boat. All i can say is Wow. Its a smart charger which means it does all the thinking for you in the aspect of temperature, charging, and battery maintenance. No regrets even though the price was a little steep. ... show more

  • Works great as a maintainer
I used cheaper battery maintainers, I threw them out. This is keeping my series bank of 2-12 volt batteries maintained at over 24v. And no battery failures!

  • Potential Issue w/ 1 Bank Failing For Some but Great Warranty
First off, this is my 6th NOCO product and all have been awesome. Great chargers, boosters, etc. Quality and performance has been superb! This GEN 5X2 forced me to have to use their customer service, warranty, etc. which has also been stellar. These GEN 5X2 dual bank chargers seem to have a common issue with one of the banks failing. One bank, mine was the second bank that failed, blinks between the charge bar and the standby lights. No matter the battery, the fuse, the connection, etc. A way to test it is to use a multi-meter to test for continuity between the positive and/or negative battery lead on that bank with the a/c power cord prongs - all disconnected, unplugged, no power, etc. The good bank will have some continuity like 36-37ohms. The bad bank will have nothing, pure open circuit. If it happens within the return with Amazon then use that. Otherwise, if its under the 3yr warranty then use no.co site to contact customer service for a warranty claim. Mine was after the 30 day return window. Initially buying it we only had one battery on our boat, knowing we were getting a second house battery. A couple months later we installed a second house battery on our boat and connecting the second charger bank, it immediately started the dreaded blink between the first charge indicator and the standby light, so that bank never worked. Not sure it is an immediate fail for others but was for ours. NOCO customer service was quick and easy. I reached out late at night with their request a call option on their website. The next day got a couple calls because I didn't have my phone near me, an email with troubleshooting steps, and next steps for a warranty claim. They'll let you ship it in and wait for a return after receiving and testing the failed unit. Or, they'll let you buy a replacement from their website - which was cheaper than here on Amazon - and refund the purchase once they've receive the return faulty unit and test it to verify the unit is faulty. I chose this option for a quicker replacement. 4 stars mainly for the unit failing but definitely love their products and am now a fan of their customer service. I'll follow up with review if the replacement unit fails and drop stars. If all is well, I think 4 is sufficient for an otherwise great product and company but consideration for this mishap. ... show more
