Whats the most high cranking battery you can get for the 997 turbo? Not so concerned about weight. Just cranking power.

Thank you!

Bosch AGM is one alternative:
Size group - H8 850 CCA / 1020 cranking amps
Size group - H7 800 CCA / 960 cranking amps

Not sure why you're looking for cranking power. BTW, H7 is OEM size, H8 is 1.5 inches longer - it will fit in the tray but you may have to modify hold down clamp.

A few other options for you to consider..

I have been installing the East Penn brand AGM's for 4 years..

The are one of the LAST battery companies in the USA.. Made in the USA

The group 9A94R = H7 I run this battery

The group 49 = H8

Interstate AGM battery part MT5-94R/H7 is a perfect fit. 850 CCA.

There's an Interstate Battery distributor near Pasadena, went there once or twice, had the owner's son, a newly minted lawyer, just passed the bar exam and looking for a job, install the battery for $5. Gave him my card and suggested I might be able to help him find a job, but never heard from him. Perhaps he is still installing batteries at $5 each.

Recently I just have an Autozone battery (H7), works fine, failed after 2-3 years recently, and they handed me a new one free under warranty. I just don't see the mystery of batteries unless you are looking for some overpriced weight reduction, they all seem to do the job (and it takes all of 5 minutes to install them).
