So if you’re wondering how much it might cost you to replace the battery, the folks at iFixit have completed their repair guide for the MacBook Pro and has estimated that it could cost you a whopping $500 to have the battery replaced. They are also working under the assumption that the “technicians follow the safer Apple-suggested procedure and replace the entire upper case assembly along with the battery.” We can’t say we’re too surprised since iFixit dubbed the MacBook Pro with Retina Display as being the “least repairable” laptop to date. $500 is indeed a lot to pay for a battery replacement so if you are still considering getting a laptop that will last you say, the next 5-6 years, then perhaps this is something worth taking into account.
