NOCO Chargers are Garbage - What's a better brand?

[Torquin]

If I have a dead battery, I pull out the RN, but I use the Battery Tender and Noco chargers, even a Harbor Freight smart charger now and then, for batteries that have at least SOME charge on them. I have not had a problem with any of them yet, except that the Noco battery repair mode seems to only make things worse. Tried the repair mode on several batteries and none got better, only worse. I bought the Noco specifically for the repair mode.

Battery Tender 2/8/15 charger.
If you leave the charger on over night, it will discharge the battery down to about 12.5-12.6V.
On a battery that is almost fully charged, it will say charging 80%, I know it should be topped off in 5 min., an hour later, still saying charging 80%. Unhook one terminal clamp then hook it up, then fully charged 100%. I done this on 4 or 5 good and new batteries. Years later still using the same batteries.
I sent the charger in, $15, they sent it back in the same box and it didn't look like it was taken out of the box.
I have an 2 electronic battery testers and State Lic. Mechanic.
They said they did me a favor, I guess not charging me to send a broken charger back.
After I purchased the charger I noticed about 30, 1 star ratings with the same problems, a month later they were gone, I wonder what happen to them?

I have had numerous good chargers. Schumacher has been my go-to for many years. This one in particular: https://www.amazon.com/Schumacher-SC1280-Charger-Automotive-Batteries/dp/B0797KK3N2

But believe it or not, when I moved to lithium batteries, I got this cheap one and have been VERY pleased: https://www.amazon.com/gp/product/B0BN1W15D6/

This little $25 charger has been excellent. Hard to complain about perfect performance with my LiFeP04 batteries.

I'm not sure that desulfating thing is anything more than a gimmick but it works great as a charger.

That process lets well used lead acid batteries work like new.
