Sooooo much better than my Noco 2amp charger I was using and was able to recover the gel battery on my wife's car within 24 hours

My charger developed a fault within the guarantee period which ended in November 2024, but I was unwell and ended up in hospital so was not able to make a claim. Last week I decided to contact the supplier and explain my situation and ask them if there was anything that they could do to help.I got the following reply within 24 hours: -"While the GENIUS chargers do have a three-year warranty - we do know and understand that things come up. As such we can make exceptions on a case-by-case basis".Several discussions followed and I provider them with photos, a video and tried processes that they suggested after which they said that they would process my claim under the guarantee and a new Genius 10 arrived yesterday, 8 days after I first contacted them.I have always been aware that NOCO products are of very high quality and would highly recommend the Genius 10. Now I have found out that the customer service matches the quality of their products.It's great to see a company being understanding and flexible to assist customers and take their personal circumstances into consideration.Thank you NOCO.

This is a brilliant bit of kit. I had the 5 before and it died a death after a few months. This is a beast and works very well for both my motorbike and car. It trickle charges, charges from flat and can repair too. Not complex operations or manuals, just push the button to specify the type of battery you have and this thing does the rest.Don’t bother with the lower powered and cheaper models. Save your money and just by this one.Highly recommended!

We have been having issues with both cars that we own over the last 6 months. During lockdown the cars were not nearly used as much as they were previously, therefore the batteries appear to have somewhat suffered! Modern cars now have a lot of extra electronics that are 'always on' and this provides a constant draw on the batteries. Both vehicles stop/start stopped working and my car kept flashing up low battery every time i turned off the ignition. As a result i decided to invest in a battery tester to see the state of health of each of the batteries.My partners car flagged up 'replace' with a health of only 11%, mine was 'Replace' with a health of 53%. When i researched prices of AGM and EFB batteries i was astonished to see how much they were. For two batteries this was going to cost me nearly £500. As a result i decided to see if i could revive them. Having spent a lot of time researching the best way to do this i came across the NOCO chargers. The 10amp one seemed to fit the bill for me. Whilst this was expensive the reviews were good and it included a repair mode - besides it was a lot cheaper than two new batteries!The NOCO Genuis 10 is a well built substantial device, even the battery clamps are very well made. Much better quality than my older 12v smart battery charger. Instructions were simple and easy to follow, although the print is super tiny so i did find it a little tough to read. I charged each battery to full which strangely only took a couple of hours. The LED charge status lights are simple, no percentages just a increasing bar graph which changes colour according to the SOC. When each battery hit the maximum the NOCO pulsed green. I then started the repair mode. This takes 4hrs. I then tested each of the batteries again with my computerised health tester - unfortunately this made zero difference to the heath of either battery. I kind of expected this on the EFB battery noting the health rating, however i was hopefully it would repair the AGM. On the smaller EFB battery the health had even decreased from 11% to 6% after the repair mode, the charge however had gone up significantly. It was clear that i needed to replace both of the car batteries. I feel it was worth a try though - shame it didn't work out for me.Would i recommend this device? It has glowing professional reviews, it is very well made and feels like a quality product. Yes you can get much cheaper chargers, however you really don't know what these are doing to your batteries. I am happy with my purchase and will use the charger to do top up maintenance charges on both cars periodically. One thing i would have liked on this device would have been a digital display to provide more information such as charge percentage and voltage etc, alas this only has basic LED lights which provide very limited information to the user. It you want to look after your expensive batteries, and are willing to invest some serious cash then i don't think you can go far wrong with the NOCO, just don't buy it solely for the repair mode as you may be disappointed with the results.I hope that you found my review helpful
