The PA2498U cells all measured about 0.10" (~2.5mm) larger in diameter than the PA2503 cells they replaced, so some judicious Dremel work was performed on the small pads and bridges within the PA2503 case, to get it to close properly over the larger cells. Put everything back together with Shoe Goo as battery-to-case adhesive and a little fast-set epoxy for the seam. In the 2498s Toshiba used a black resilient goop to adhere the batteries to the case interior, presumably to prevent their shifting around. Shoe Goo works very well, silicone caulk is probably as good. In the PA2503Us Toshiba used double-sided tape for this. Be careful splitting the case, the seam edges are easily mangled. These home-brew batt packs appear to function perfectly. As Konrad says, they charge from the charger fine, and I've run one in the L100CT for over 4 hours, with light activity. Both Tosh Power Saver and W98 Power Management show the battery status correctly. There was a seller on ebay who was offering new, boxed PA2498Us for $5.00 starting bid. I was lucky enough to buy three for a total price of $36. Unfortunately, this guy's been kicked off ebay. Considering the price of even used PA2503s, this shade-tree re-assembly work is worth the effort.
