I got this MBP 17"

It turns off when powered from battery and the charge goes below 70%. After this it can only start again when power supply is connected.

It then starts to slowly charge. It takes long time to get to 100%.

Tried another battery - same symptoms. Cannot start from battery power only until it reaches around 70%.

OS X says battery condition is normal
