@incendiary_dan It depends a bit on how big a battery you have. I will say that my netbook with it’s low-power CPU and 2½–3 hour 3-cell battery charged a lot quicker than my T135 with it’s more power-hungry innards and 6+ hour battery life. And to be honest, I gave that netbook away long enough ago to forget how long it took to charge. However, the OP has a Toshiba NB-series, which comes standard with a 6-cell pack and about twice the endurance of your Eee or my old Aspire One; it is more comparable to my T135, though a little less since the Atom draws a bit less power than a dual-core SU4100.
Also bear in mind that quick-charging a Lithium-ion battery will heat it up, and heat will DESTROY a Lithium battery in short order. That means that, by design, the charger only puts out so much amperage in order to not melt stuff.
BTW, age (or rather, exposure to oxygen) also destroys a LiON pack. About 15%/year is typical, though if you have a habit of storing it in your car during the summer months, you can lose as much as 60% of the battery capacity in 3 months. Like I said, heat kills them.
