Does this battery charger desulfate the battery? I can't find that it does anywhere.

Do any of them desulfate? I have my doubts. In for one anyway, I have several, but none go beyond 6 amps. Most are only one to four amps, with no voltage display.

Yea, I ordered one too, the price is very good for a supposed good brand. I still don't think it desulfates the battery, but I have my Noco Genius 1 for that I guess.

In for one. Needed to upgrade my 9 year old CTEK. Its still working great but is not compatible with LiFePO batteries(that are in my future). Thanks OP, repped.

Edit: Just as a comparison there is a GW 1.5 Amp on sale at Home Depot for $38.50, 10 Amp is $78. So, better deal hear for sure.

All of the Noco Genius line says that it desulfates. To be honest, I don't even know if internal battery sulfation removal is real or just a marketing gimmick. I bought one anyway since it is a good deal and I'll use it.
