    Apple will give a warranty against hardware defect on the substitute battery for one year from the date of the Out of Warranty service. Please note that the series is a unpreserved thing and after a period of usual use the battery's skill to hold an electrical charge will be diminish. A replacement battery that has botched because it has been inspired via normal use is not enclosed under warranty.

    A normal interpretation for Full charge ability is about 5200-5400 mAh (milliamp hours). That translates into now over 4 hours battery life. Cycle count is how many times the battery has been worn to ability and invigorated. Battery health is a word telling overall life expectation and condition of the battery. Doing the math, that denote the Full charge ability be supposed to be around 4160 to 4320 mAh after 300 cycles. If your Macbook battery is deteriorating, like mine, it should read fewer than 3250 mAh, with a Health of “Fair” after far less than 300 cycles.

    For minimize battery usage, stay the brightness level of your MacBook Pro to a minimum. The brighter the screen is, the additional power the series consume. Also, turn off the backlight on your keyboard by using the F5 key to minimize power expenditure. Also you need to Turn off the Bluetooth function on your MacBook Pro when you are not using it because it uses a lot of power. To exit Bluetooth, Open System Preferences, click on Bluetooth, and mark as uncheck the box next to “ON”.
