Replacement battery

What battery is recommended for my 1982 911T?
The Interstate MTP-91 needs to be replaced and is no longer available.
It's hooked up to a trickle charger since it's driven infrequently.

Interstate still lists a MT-91/T6. Practically every battery supplier carries a Group 91

Did you mean a 1972 911T?

Wonder if he meant he has a 1982 911SC Targa. Or a 1972 911T...

Either way I wouldn't put another conventional lead acid battery in the car if simply for the reason to avoid corrosion in the battery tray. An Odyssey 925 AGM is too easy of a choice.

Yeah, I run the PC925 in my '77, but relocated to the smugglers box with a Rennline mount. Frees up space for the pump, toolkit, and a trickle charger.
