I doubt you'll find the battery life, I couldn't even find a model number so I dont think you'll find info about it anywhere else.

Newegg has a similar product for about $30 more, Looking at the photos it might be the same device but it's hard to tell without a brand-name on your site or a model number. (it's battery life is 8/6 hours)

If it's the same one, and you trust the retailer where you originally found it, you may as well get it there and save a few bucks. If you're not sure newegg is about as reputable as it comes.

yeah i was going to, also before i buy the targus speaker book can you reccomend any other good speakers for around the same price (ive found them for around £9) thanks in advance.
