Most MacBook or MacBook Pro laptops have batteries that are good for between 300 and 1,000 recharge cycles, depending on the model (Apple has published the specs here).
But you don’t have to buy a new MacBook when the battery is worn. You don’t even have to take it to an Apple Store for a genius to wave their magic wand over it. You can, in fact, replace the battery yourself.
The MacBook going under the knife here was a mid-2012 13-inch A1278 MacBook Pro that has nearly 2,000 recharge cycles on the battery, which is well over the rated 1,000 which Apple considers as its limit.
For the job I got a complete battery replacement “Fix Kit” from iFixit. The kit costs $79.99, and is an excellent value.
Note that there are different battery kits for different MacBook models, so it’s important to choose the right kit for your device.
