check my post above. these lower readings very well could be more a result of your driving habit than the real condition of the battery.ahagge wrote:As I've now had my battery for just over a year, so here's another update:ahagge wrote: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):
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...
- 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
Update: Updated graph showing correct SOH values
Comments: With the colder weather of winter and spring, the battery has been holding pretty steady. I'm currently at about 258-260 GIDs, 60.25 AHr, 94% SOH and 90.4 Hx. We'll see what happens during the next 6 months...
my stats were lower than yours but a change in driving habits (extreme change I do admit) changed that.
Keep in mind; I only believe about half the change as there is an obvious increase in range, slight though it may be and the battery will drop back down to normal in a day or two when the extreme driving stops.
