Lithium-ion batteries have terrific properties which have brought about a revolution in all the pieces from tiny flashlights to Ford vehicles. Sure, you need to take them significantly in the event that they present any signal of getting a bodily failure, corresponding to swelling or smoking, however that’s thankfully an extremely uncommon incidence relative to the huge variety of lithium-ion batteries in use.
Carrying down over time is kind of widespread and could be irritating as a Mac laptop computer proprietor, used to many hours of use, now eking out only a few. In contrast to older generations of batteries, Li-ion batteries don’t have a reminiscence impact, the place incomplete charging can scale back their most cost. Fairly, the chemical nature of the batteries causes a normal depletion over time in how absolutely you possibly can safely cost them.
Apple does present a guaranty for laptop computer batteries that’s pretty beneficiant: in case your battery drops beneath the flexibility to retain an 80 % cost inside its first 12 months (or inside three years with AppleCare+), Apple replaces it without spending a dime. Exterior of that interval, the associated fee within the U.S. seems to be a flat $159 for MacBook Air fashions and $249 for MacBook Professional fashions. There’s additionally a delivery charge if it must be despatched off for service.
That worth is simply excessive sufficient that you just would possibly take into account swapping out the battery your self. There’s a powerful dividing line, nevertheless, between it being worthwhile and it being one thing finest left to educated professionals–notably as a result of these educated professionals might be accountable if one thing goes mistaken within the course of and they should change extra than simply your battery. If Apple handles your battery alternative, they’ll swap out your total pc in the event that they break it within the course of.
I usually begin at iFixIt’s Mac Laptop computer Restore part in its how-to guides.
For older laptops, corresponding to a 13-inch MacBook Air (early 2017), most individuals taking care should not have any hassle changing its battery. A contemporary battery prices $60 from iFixIt (or $70 with all of the required instruments), the time estimate is 10 to twenty minutes, and it’s simply 5 steps to get the battery out and a brand new one in, after which the reverse variety of steps to reassemble. That’s $100 lower than Apple’s pre-tax, no-shipping worth.

For newer ones, it’s an entire totally different ball of wax, as Apple has used adhesive in additional methods than it as soon as did to carry issues into place, usually in lieu of screws and different connectors. That requires extra care in elimination and extra alternative components to revive. The alternative components for newer merchandise are dearer, too. So together with 30 to 120 minutes and almost 50 steps (about 24 in and 24 out) to change the battery in an M1 MacBook Air (late 2020), you’ll additionally pay $120 for the battery and want a number of instruments you won’t personal when you haven’t finished this earlier than (an additional $10 if bought with the battery). For a couple of bucks extra, you possibly can have Apple handle all this for you.
My rule is that if I’ve to take away greater than about 10 screws, it’s doubtless that it’s too difficult to be well worth the danger I’ll harm one thing alongside the way in which. And spending an hour or two–and presumably longer if I reassemble it incorrectly and need to repeat my steps–is probably not the most effective use of my time versus different work or plain rest.
