First let me say that my 340 tractor battery is my old pickup battery so it's not new by any means. I keep a battery tender on it all winter and I've been able to start my 340 a lot easier in sub-zero temps. I notice it if I don't have that battery "topped off". Like cowman, I don't put a tender on equipment that's going to stand still all winter. I pull a battery cable and call it good.

Desulfation is not a new idea. I doubt that a small charger is capable of this. The idea is to hit the plates with a very high amperage charge for a short time. This knocks off some of corroded lead that sinks to the bottom of the case. This is done at the beginning of the regular charge. If enough lead is collected in the bottom of the case it can short out the plates. I don't think reinventing the battery is a good idea.
