Get everything out of MBP drained battery

[RELOAD911]

Hey everyone! Here's the thing: I've got a Macbook Pro with Core Duo and a drained battery inside it. 13% capacity (739 mAh) to be exact. MBP used to turn off at 86%, I did a SMC and PRAM reset, now it turns off at around 79% which is around 3-5 minutes. The question is - is there a way to get the most out of it? And is it actually supposed to turn off at that percentage when capacity of battery is low?

Yea, I know. The OS alarms that I should service the battery and it's the easiest solution etc. But! Is there a way to get everything out of it? Thanks in advance!

From your description that battery sounds like a lost cause. Your going to need a new one. Is your computer under warranty? Have Apple care? If not you can still try taking it to a store to see what they'll do. And yes, the computer can and probably will shut down unexpectedly w/ a bad battery (I had some data corrupted that way )
