Now that you know about a couple of Dell Streak accessories that can be used to charge a spare battery (e.g., external charger and unbranded dock), the idea of actually getting an extra battery is probably becoming a little more appealing.
The idea of paying $39.99 for the official battery from Dell.com makes it less so, though, and the fact that eXpansys is now asking for $26.99 for its third-party Streak battery when it originally wanted $16.99 certainly doesn't help. There are some great prices to be found on eBay, sure, but you may not want to deal with random sellers or waste time watching an auction so you're not outbid at the last second.
But don't give up! It turns out that you can save some serious cash on a third-party 1530mAh battery at DealExtreme. The price there is a only $9.50 per battery. And if you order 3 or more, the bulk rate kicks in and lowers the price of each one by over a dollar.
Free worldwide shipping is included when you pay full price, and bulk rates are subject to a $1.70 flat fee for registered air mail.
I don't know if these batteries have been tested to determine the difference between their actual and stated capacities, but at these prices, do you really care?[DealExtreme]
