The advantage of this particular charger over others is the 12V repair mode.
Amazon product: NOCO GENIUS5, 5-Amp Fully-Automatic Smart Charger, 6V And 12V Battery Charger, Battery Maintainer, Trickle Charger, And Battery Desulfator With Temperature Compensation
Nice little plug and play charger. Light weight and compact. I had an aging 12V car battery that I hooked up to repair mode. Took all night but in the morning it tested green and holds a charge. Repair mode is actually a “thing” and aging batteries really can be given new life by desulfating. Thought it was just a marketing scam at first but by all accounts it really works. | Note: The repair mode instructions in the manual and online are incorrect. They say “Standby Press and Hold 3 Seconds ” which is not correct. The correct way is to Press and Hold (3-4 seconds) to get into 6V mode , then select “Repair” mode. A few YouTube videos also show you how. Once I figured that out it worked great! | Wish it had a 12v power source mode so I could have kept my car electronics working while the battery was disconnected for repair but its not something done that often anyway.
