I'm a little late to the party here. Only now have I seen these....and for the R/T/Z 60/61, as well!
I have a few questions about these....
It would seem these are aftermarket creations, not replications. I've seen no TP series that had a 12-cell battery. Plus, I always assumed that the other replicated batteries used casings molded from actual OEM batteries, or some kind of covertly obtained mold impressions. With there being no OEM counterpart to these, I suspect they used a 9-cell mold, and skimped on thickness in the new expanded area, rather than designing for 12 cells.
That last picture shows an area that would easily fracture due to stress if there isn't increased thickness, or density of plastic. Is there a tactile feeling of thickness or "thinness"
there? Is there much flex?
Aesthetics aside, that is the bigger potential deal-killer when you consider it's a weight-bearing structure.
Not my cup of tea, but an interesting modification. I'm curious, doesn't the battery have a chip or processor in it that tracks charge cycles and whatnot. Does the 12 cell show up in the power manager as a 9 cell or does it actually show up as a 12 cell and report correct life cycles?
No one actually responded to that. Can someone do so in detail? Maybe a screenshot of the details in Power Manager?
Yes, dr_st. One drawback is that it doesn't fit in a dock. I have 2504 docks at work and at home; I stay with the standard 9-cell on regular daily uses and carry the 12-cell for long days at meetings or at Starbucks.
Yes, it's not quite a moot issue, but an inconvenience to be sure. This battery would cater to those without docks, or spend little time docked. Those who do use their TPs docked more often than not, would probably lean more towards a 6 or 4-cell for lesser cost.
