Hello, I installed a new battery recently. My macbook recognises it, it works well and all, but when it gets close to being discharged (close to 5-3%) it suddenly shuts down (without hibernating). I tried the standard procedure to calibrate the battery (full charge + full discharge) but it didn’t work, despite several attempts. Any advice?

mmm… I think you’re expecting more from your system than it was designed to do! First I don’t recommend you deep cycle your system to this level. Each time you do you loose a cycle life! Your battery only has at best 1000 cycles. Recharging from such a level will cause your battery to heat up and a bit of the batteries electrolytic will boil off, even when the thermal control within the battery kicks in to reduce the extreme boil off which is when your battery blisters up and then can explode. Overtime it will still swell up while not to the extreme, it will cause stress to the system. So why is your system not going into sleep? There are different sleep modes! Putting Your Mac in Sleep Mode So you might be just getting into Hibernation Mode/Safe Sleep Vs Sleep given the deep discharge this makes sense! Lets review your battery and the charging logic to make sure your battery is healthy. Install this gem of an app Coconutbattery paste a snapshot of the main window so we can see whats happening.
