Any charger is good to charge batteries as long as one disconnects the charger. Few chargers are good to recondition the battery. Only a handful can be left connected for prolonged float charging. Many float chargers kill batteries and/or car electronics. This is where CTEK and couple others distinguish themselves.

Sometimes you need a dumb charger to force charge.

I have a CTEK MUS 4.3, HFT Centech 2/10/50 and Battery Tender Power Plus. Battery Tender killed a Deep Cycle on float, couldn't revive a dead automotive battery after 48 hours. You can leave CTEK on for years.

I couldn't agree more. I purchased it the last time it was posted on SD and was able to revive my 4 year old battery without any issues. Before using this, my car battery needed to be jumped if the car was sitting for longer than a day. And I learned that jumping your car is really bad for the battery (read somewhere it is similar to giving a CPR to a human). So if your battery is weak, stop jump starting it and buy a smart battery charger like this.
Time to buy a new battery.

If so, then I am wondering what makes CTEK to be able to not kill batteries on a float. I have a Noco Genius 3500 with a 200ah SLA AGM battery on float for past 2 months, but have not been able to test the battery because solar project has been on hold

I've had my Battery tenders on all my outdoor stuff for over 7 years off and on, mostly on. No issues and batteries have lasted me longer than ever so 🤷 ♂️

I use the battery tender off and on and still replace batteries 3 to 4 years
My buddy is the same and has a lot of batteries
It's nice to have a charged battery when you want but the tender is no guarantee to save a battery or make it last longer

I have this and kinda regret buying it honestly. It does work, but as others have pointed out, it just screams of cheapness.

The clamps are bulky and don't grab on side post batteries. The "smart" features end up being more of a PITA than a help, especially the auto-sensing capability that attempts to determine if you have a 6V/12V battery or a car/motorcycle battery.

As long as your battery remains at 7+ volts, it'll likely correctly sense that it should charge at 12V but if you drop below 7 volts, forget it. I had a battery that dropped to around 6V and the stupid auto sense would keep choosing a 6V battery and immediately say it was fully charged. I ended up having to jump the car, let it run long enough to charge off the alternator to get to around 12V, then quickly put the charger back on so it would correctly choose a 12V battery.

I will say that after doing all that, it did a good job of bringing that battery back from the dead and I got another couple months out of it before it totally died. The Repair mode took nearly 24 hours to complete and I questioned if it was working at all. I don't know what repair mode actually entails, but the manual specifically states that the charger must be "guarded for more than 15 minutes to prevent accidents". The "more than 15 minutes" statement makes no sense to me whatsoever but I'm guessing they want you to monitor the charger the entire time it's in repair mode to clear themselves of liability.

Overall, I feel like I should have just kept my $22 and put it toward a better quality charger the first time. The build quality seems like something you'd expect from Harbor Freight. At the end of the day though, it does appear to work if you can work around the smart sense mode, the cheap clamps and the short cables.
Thanks, I was regretting cancelling my order after someone pointed out Noco genius1 is only 1 amp and would take days to charge a dead battery. My battery won't start the car if I don't drive it for a month. I dunno how low it is by then, but the last time I waited about 3 months the battery was reading 0.

Dunno if I wanna be charging constantly every month, for a day. A hassle, but this car must have a parasitic draw since it can't hold a charge for more than a month with a less than 2 year old battery. I had Advance charge it and they said they wouldn't replace it under warranty since it charged all the way to full on their charger.

Seems dead now. The 20% off code works, but the code N6WQ83X7 is invalid.
