Can't identify these power diodes

I'm attempting to repair a MAC (garage) battery charger/booster, 12/24v, 50/25A and 325/470A boost.
Some of the diodes are short circuit, the markings on them are: T2K12-6 and T2D06-4
There are 8 diodes in two blocks of 4 feeding the positive output of the charger.
I can't find, so far, any spec for these diodes.

Just replace with any diodes that can handle the current... ebay.

Thanks, although choosing the right spec is rather daunting in view of the high boost amps. The MAC charger has a 120 amp re-settable trip on the +ve output but it seems this was always tripping so they bridged it out which probably caused the demise of the diodes.

I should think they are rectifier bridges and there will be an output to earth ...chassis.
One bridge is for charge and the other for boost... I could be wrong but that kind of makes sense.
