NOCO Genius G7200 12V/24V 7200mA Battery Charger

Perfect product.. very robust and high quality.

I had to post this because If I could rate this 0 stars I would. The unit worked great until it died. Yes there is a 5-year warranty but you have to write a check (yes a physical check) to the company to cover the cost of any upgrades made to the product line since your unit was made. Additionally, the warranty process is ridiculous so good luck getting your unit back. It has now been two months and still not had my unit sent back.....

I attached my cheepo float charger to maintain my 74 Honda CB360 battery. OOPS, dummy me forgot to plug in the charger! Three months later not only is the battery dead, also 2 of the cells are BONE dry. I put in distilled water to raise the 12Amp "flooded wet cell" liquid level to midpoint between the lines at the top. I attached a Fluke voltmeter and saw 3 volts, ouch - 50 or so for a new battery. I thought of my G3500 V2 (with "repair") and thought "why not". To my surprise it started to charge - took a mighty long time - about 14 hours on low setting. Next I ran "repair" till a green light (about 4 hours). As there was some "condensed solids" at the bottom of some cells, I made a marathon effort. I alternated between repair and low charge for three days, slowly as the bubbles rose; the solids dissolved and the bottom cleared. I was stunned. Would it start the long sitting cycle, and if so would the charge last at least a week? YES to both!! Frankly, I was 99% on the way to just ordering a new battery. I probably would but for the fact that my ancient 74 bike has a "kick starter". I am delighted with what the G3500 V2 did. A click on "this was helpful" would be appreciated.

If I had written his review yesterday I would have given it 5 stars. It has worked spectacularly. This said, today I was charing my truck battery. All was fine, when I looked out to see smoke coming out of my hood. The thing was fully on fire! I am so lucky I saw it in time. I could have started a serious fine. I am hoping I can get my money back, but I don't even know what the warranty is.This thing is dangerous!

this is cheaply made. kept showing one battery had a short BUT using a CTEK it charged the battery and all was ok. the NOCO has an intergrated eyelet which is very impractical. the manual is defecient in describing things, confusing. i returned and bought a CTEK which is so far superior, no wonder it is recommended by mercedez, bmw, jaguar and used in jay leno's garage. it has seperate clips and eyelt cords, a carrying case, a nice manual, easier to use and understand, shows exactky what is being done by the charger. the CTEK 'fixed' batteries that the NOCO simply showed an error code, such as battery short. i wiould never buy nor recommend the NOCO. those that gave high reviews must never have used the CTEK. the quality, workmnship, ease of use is truly night and day to the much lesser NOCO. when i tried to contact NOCO for explanation on how to use and whatwas meant in the manual (which is a small hard to read single piece of paper, it took a week for a response. then the tech had no idea of the error signals or able to clarify the manual. their warranty seems to me near a sham; you have to pay return fees and the unit is prorated.

I purchased the NOCO Genius G7200 from Auto TrenDs in late October 2016. I "repaired" an old battery that was in a work truck that had been sitting for over a year. The battery is still working to this day so the NOCO did the trick. However, when i got the charger out to charge my boat battery the first week in May it didnt work. There was a high pitch sound coming from the NOCO. It wouldn't charge the battery. I got one use out of this $90 charger. I am attempting to return the unit to the Amazon seller Auto TrenDs, so far they have not responded.
