Since the latest posts have been about 2011 Lizard Pack retrofits (and since I live literally blocks from TomT), I'll update my
previous post. I have a 2011 SL-e with a Lizard Pack (-E variant), installed in April and surviving one San Fernando Valley summer thus far:
BTW, here's the actual numbers (about 10,000 miles of driving):
- GIDs went from 278 to 259
- AHr went from 66.14 to 59.749
- SOH went from 100% to 93%
- Hx went from a high of 102.30 (about a week after the new battery was installed) to 89.47
So as you can see, this new Lizard battery has suffered a 10% capacity (AHr) loss in about 8 months. What's interesting is that as Tom said, the capacity drop is continuing even though colder weather is setting in. I'm not a happy camper... :x
Update: Updated graph showing correct SOH values
