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 (http://tiplanet.org/forum/viewtopic.php?t=11654&lang=en), 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 (http://ourl.ca/19500), 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! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

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? ;)
