It has an RC of 195. The NOCO’s guide says this charger is able to maximize up to an RC 230 battery. Taking ~17 hours. It did this battery in 15 hours. The charger did get hand-held hot at ~145F. The time and energy it put into this battery says this is still a good capacity battery. NOT “ruined”.
Next I tried to save a Group 34 AGM battery that had conked out at 4 years. NOCO Genius 10 charger after trying on AGM setting gave me a “failed-battery” indicator light. So I forced it into “Repair battery” mode. This rapid cycled the charging voltage between the 13 volts to 16 volts for 4 hours. Still get a “failed-battery” light.
Then I put it to work on the taken out Chinese small seal lead-acid battery from the Harbor Freight 9500 Inverter-generator:
“Repair Battery” mode charging rapidly alternating between 16 and 17 volts. Amperage must be limited in Repair mode as the charger and batteries are not heating or gassing out.
Ha! And I still would not trust this 3 year old small, minimum sized old lead-acid battery.
Lead-acids need to be sized 2X to 3X the actual capacity needed. At best they will degrade 1% loss per month. You size to still be able give you enough after 3 years for another 2-3 years of useable life.
Not hopes and dreams . . . practical, applied, technology. A solid 130 years of experiences in lead-acids. Telephone/telegraph services; cars/vehicles, submarines and others. Ha! Only 60 years or so, in my lifetime eating holes in my cotton wear. Work around lead-acids . . . fingers tongue test, taste fizzy; wash the cotton clothes fast to maybe save them! Wear leather; sheep’s wools; polyester blends; and nylon knits.
I gonna’ be loving this new full featured C1 charger.

Usually tesla doesn’t invent stuff like that, they usually take an idea that was thrown out, try to improve it, and rebrand it as their own… This might be the case… because if you have two stepper motors drive a ball joint. It is the ball with a rod coming out of it, and you have two gears that have to not bind on the rod. Then you have to hold the whole thing together. Getting a ball designed is probably the easy part. It is an intriguing problem. It is a good question to ponder while mowing the lawn.
