It depends on which Apple MacBook Pro 15″ you own, because the line covers about 77 models and 18 distinct part numbers. Voltage runs 10.8 to 11.26 V and capacity from roughly 55 to 95 Wh, all lithium-ion. For example, a Late 2008 to 2010 unibody A1286 uses the internal A1281 (73 Wh), while a 2011 to mid-2012 unit uses the A1321 (77.5 Wh). Check your model number on the bottom case to confirm which pack fits.

Start with the model number printed on the bottom case in the form Axxxx, then note the year and screen type (Retina or non-Retina). Those three details point you to the correct pack among the 18 part numbers we carry, since voltage (10.8 to 11.26 V) and capacity (55 to 95 Wh) shift by era. A Retina Mid 2012 to Early 2013 takes the A1417 (95 Wh), for instance, which will not fit an earlier unibody model.

Replacement batteries for the Apple MacBook Pro 15″ run from $64.99 to $87.99, depending on the model and capacity. The wide range reflects the different eras in this line, from the early removable A1175 packs to higher-capacity internal Retina units around 95 Wh. Confirm your exact model number first so you order the part that matches your machine and you are not paying for capacity your laptop cannot use.

No, they are not interchangeable across the line. Each design era uses its own pack, so an A1281 (73 Wh) from a Late 2008 to 2010 unibody will not fit a 2011 to mid-2012 machine that needs the A1321 (77.5 Wh), and neither fits a Retina model using the A1417. With 18 part numbers covering about 77 models, you must match by your exact Axxxx model number, year, and screen type rather than by the 15″ label alone.

The main differences are install method and capacity. Pre-Unibody (2006-2008) batteries are removable via a bottom latch with no tools. Unibody (Late 2008-2012) packs are internal and held by screws (a #00 Phillips or Tri-wing). Retina (Mid 2012-2015) and Touch Bar (2016-2019) batteries are glued to the top case and need isopropyl alcohol to remove. Capacities climb from around 55 Wh on early models to roughly 95 Wh on Retina units.

Look on the bottom case for the model number in the Axxxx format, then match it to the correct battery part. Common part numbers in this category include 020-6380-A, A1322557, 661-5229, 020-5071-B, MA348LL/A, and MC-MBOOK15. Some packs also carry their identifier printed on the battery itself once the back cover is off. Pair the model number with the year and screen type to confirm the right pack among the 18 we list.

Yes, though difficulty varies by era. Pre-2008 models need no tools, just slide the bottom latch and swap the pack. Unibody models from Late 2008 to 2012 require a #00 Phillips or Tri-wing screwdriver to remove the back cover and the screwed-in battery. Retina (Mid 2012-2015) and Touch Bar (2016-2019) batteries are glued to the top case, so plan for isopropyl alcohol (98% or higher) and patience to avoid puncturing the cells.

Watch for rapid charge drain, the laptop shutting down well before reaching 0 percent, or the system no longer holding a charge near its rated capacity (these packs are 55 to 95 Wh when healthy). You may also see the charge cycle count climb high in System Information, or the machine staying alive only while plugged in. If your A1281 or A1618 era pack shows these patterns, a fresh battery matched to your exact model will restore runtime.
