Thought I'd post this for those who might be thinking about getting a stand alone battery charger. I ended up getting the NOCO Genius 10 for Christmas and have already used it several times.
One instance was on my old Jeep's 12 volt wet cell battery. Went out a few weeks ago and found the battery almost dead. Jumped started and drove it around to get some charge put back into it. Seemed to crank fine afterwards but I knew that was not a good test. I let it sit for a couple of days before trying to start again. Nope, it was dead again.
The battery is dated 2014 (got my money's worth) but for the heck of it, figured I'd try using the NOCO charger's repair mode on it. I let it finish its thing then reinstalled into the Jeep. The starter sounded better than ever. To make sure, I let things sit for about a week before trying to crank the Jeep again. To my surprise, the starter sounded like it was on a brand new battery. Have monitored for a couple of weeks now and the battery is still doing great. Only time will tell how much more I might get out of the 8 year old.
The charger is good for 6 and 12 volt, starting and deep cycle, wet, gel, agm, and lithium batteries. It's a battery maintainer and it can also be used as a 12 volt power supply. Not positive but I believe the repair mode is only good for standard 12v wet cell batteries.
