Use this guide to remove the glued-in battery from your MacBook Pro. This is best done with the help of an iFixit battery replacement kit; the liquid adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease. Alternatively, you can use an iOpener to apply a modest amount of heat in order to soften the adhesive before prying out the battery.
'''iFixit adhesive remover is highly flammable.''' Perform this procedure in a well-ventilated area. Do not smoke or work near an open flame during this procedure.
'''To minimize risk of damage, turn on your MacBook and allow the battery to fully discharge before starting this procedure.'''
