"10-plus hours battery life"
"Incredible battery life, plus new custom battery controls
Get up to 10 hours or more of battery life on X Series models equipped with the 8-cell system battery plus an optional ThinkPad X60 Series Extended Life Battery, which attaches via the docking connector. Select ThinkPad X61s models can run up to 12.5 hours with this same configuration.
And now, new ThinkPad X61 models provide even greater, more individual control over battery life. BatteryStretch, a new feature in Power Manager, lets you to make temporary selections in extreme situations to extend battery life beyond what your regular Power Manager settings might produce. If your battery is drawing down, BatteryStretch gives you an easy interface through which you can, for example, minimize the display refresh rate or disable certain wireless communications devices to help preserve the power you need to finish your work unplugged."
Fast det där blir ju två batterier, även om man kan ha båda inkopplade samtidigt.
Jag minns ju som sagt inte vad det var för dator (eller märke) jag såg det på, men var någon som hade rätt normal batteritid med vanliga batteriet, bättre med ett bättre och som sagt 11 timmar med det fetaste.
Men den var grym
Men undra vilken som man bör satsa på att köpa i såna fall
