A few days ago we discovered pictures of what appears to be a 6-cell, high capacity battery plugged into an Acer Aspire One laptop. Now one astute Liliputing reader has spotted a product page at CDW for a 6-cell battery.

The battery isn’t available yet, and there’s no official picture. But there is a price: $119.99. For a battery that goes with a $380 computer. That’s right, the battery costs almost 1/3rd as much as the full computer.

Computer companies have a track record of charging ridiculously high prices for batteries. But it’s one thing to charge $120 for a battery for a $1000 computer. It’s quite another to ask users to pony up more than 30% of what they paid for a computer for the privilege of running it a few hours longer. Hopefully Acer will offer a version of the Aspire One that comes bundled with the higher capacity battery for a more reasonable price. But if you’ve already purchased an Aspire One with a 3 cell battery, it looks like you’ll just have to shell out the cash to upgrade your battery whenever this thing becomes available.
