I recently bought a replacement battery for my MacBook battery. In Coconut Battery the Current charge has been as high as 8000 mah, yet the maximum capacity is listed as 6100. When the battery icon shows 100% has been reached the MagSafe light stays orange and doesn't turn green till the Current Charge exceeds the Maximum Charge.
Also, sometimes the laptop running on battery power will just shut off at 50%. When I plug in the charger it turns back on without a reboot but suddenly the battery icon shows 10 or 11 %.. Any ideas on these issues? Could my charger be defective and charging the battery too much?
