My sister recently bought a Toshiba Satellite M35X-S1142 Laptop and the battery only holds a charge for about 2 hours max. I am looking for a External Universal Laptop Battery for her. I have been searching the web, does anyone know if click here is a reliable website to buy off of. Their products sound reliable, but I would like to have some input on this because I have never used their website before. If anyone has any information on a better site for external laptop batteries, this would be great. Thanks.
