Travel Technology - Toshiba Laptop battery

Toshiba Satellite laptop model A215; has a factory 6 cell battery which lasts about an hour or so playing DVD's. I'm trying to source a higher capacity battery; the Toshiba site has a 9 cell product available, but I've heard that there are even higher capacity models available.

I've tried to shop for something better, but am baffled by the wide variety available.

Any recommendations for a simple site which could offer a good solution?

Thanks

I've had good luck shopping online at http://www.batteries.com.

They generally have third party batteries as well as Original Equipment Manufacturer (OEM) batteries.

Also, they post the electrical characteristics of the batteries. Higher Amp-Hour ratings mean more power and generally more runtime.

You might start your search with these guys.

I've used them for the past several years to get NiMH, camera, mobile phone and laptop batteries (AAA, AA, Canon, Nokia, Motorola, IBM Thinkpad, Sony Vaio).
