For back to school 2010, Texas Instuments did release the TI-Nspire TouchPad with its optional rechargeable battery, the
3.7L1230SP. You got
3.7 Volts for a capacity of
1230 mAh. Thus, a simple multiplication gave you an energy of
4.55 Wh.
For back to school 2011 came the TI-Nspire CX. But the included rechargeable battery, the
3.7L1060SP, was 14% less powerful with a capacity of
1060 mAh and therefore an energy of
3.92 Wh.
For back to school 2012 in China, they were even less lucky. The released TI-Nspire CM was including a much less powerful rechargeable battery, the
3.7L0800SP with a capacity collapsing to
800 mAh and therefore an energy of only
2.96 Wh.
In a
previous news, we noted that the new back to school 2013 TI-84 Plus C Silver Edition was including a new rechargeable battery, the
3.7L1200SP, therefore providing
1200 mAh and
4.44 Wh.
In a
another previous news, we also warned you against the new back to school 2013 TI-Nspire CX whose hardware revisions I/J/K have been rendered incompatible with the 3.1 versions required by the Ndless 3.1 and Nlaunch jailbreaks.
But finally, there is at least one good news with this new TI-Nspire CX hardware: it's coming with the new
3.7L1200SP rechargeable battery! We're not completely back to the power of the back to school 2010
3.7L1230SP yet, but it's still 13 % more powerful than the old
3.7L1060SP. So you're getting a better rechargeable battery for the same price!
So the choice is now simple when you buy a new TI-Nspire CX:
- hardware revisions A-H for Ndless 3.1 and Nlaunch
- hardware revision I and above for the new improved rechargeable battery
Which one would you choose? ;)
