I bought a brand new battery and when the laptop is unplugged from the mains and left to battery usage alone, it still turns off at 3 quarters full. All the posts i've read suggest faulty batteries, to which the OP's mostly reply that they've change the battery and still have the same problem, like myself.

My Toshiba Portege R930 turns off suddenly when it's anywhere around 60-70% charged when operating on just the battery and the mains is disconnected. So i've been searching article after article for an solution to this but still a no go.
