Great info here...

Will be replacing my battery soon and have a couple thoughts/questions.

I just replaced my battery in a 991.1 GT3 with an Antigravity Lithium Ion battery (saved over 30 pounds) and initially thought the dealer needed to be involved. After further research, it was clear all that was needed was to plug in a trickle charger while the battery was out to ensure no reset/programming was necessary. Has anyone tried this with a BWM? Everything I have read indicates that a re-register/tool is needed, so just wondering...

Also, looking to get an Interstate H9 with 950 CCA and 100 Ah; the OEM is 105 Ah and I am getting the sense that this will make a difference, hence the re-register/coding. That correct? The new Antigravity battery in the GT3 is only 40 Ah (compared to 70 Ah OEM) and have been reassured that this is not an issue and for my usage the 40 Ah will be plenty. Now the GT3 has VERY low parasitic loss, so maybe that is why? Any insight is appreciated.
