It depends on your exact year. The 2019 Intel MacBook Pro 16″ (A2141) uses a 6-cell lithium-ion pack around 11.36V, while the 2021 and later Apple Silicon models (A2485, A2780, A2991) use a different 100 Wh design. Across the full category, packs run 10.8 to 11.26 V and about 55 to 95 Wh, with 18 distinct part numbers covering roughly 77 compatible models. Check your model number under About This Mac to pick the matching part. Prices run $68.99 to $96.99.

Start with your model number, which begins with “A” followed by four digits (like A2141 or A2485), found under the Apple menu by selecting About This Mac. Pair that with the release year. The 2019 Intel unit is A2141, the 2021 redesign is A2485, and the 2023 to 2026 machines are A2780 or A2991. Since this category spans 18 part numbers across about 77 models, matching both the model number and year is the most reliable way to land the correct pack.

Replacement batteries in this category range from $68.99 to $96.99. Where your specific pack falls depends on the model year and the part number it requires, since the line covers 18 distinct part numbers across roughly 77 compatible MacBook Pro 16″ models. The Intel-era 2019 A2141 and the Apple Silicon A2485, A2780, and A2991 packs differ in design, so confirm your exact model under About This Mac before ordering to make sure you get the matching part within that price range.

No. The 2019 Intel model (A2141) and the Apple Silicon models (A2485, A2780, A2991) use completely different battery architectures, so a pack from one will not fit the other. Even within a similar chassis, M2 and M3 generations may have slight internal connector changes. With 18 part numbers spread across about 77 models, voltages from 10.8 to 11.26 V and capacities from 55 to 95 Wh, you should always match your exact model number and year rather than assume cross-compatibility.

The biggest split is Intel versus Apple Silicon. The 2019 A2141 uses a 6-cell lithium-ion pack near 11.36V and is often part of a top-case assembly, while the 2021 A2485 introduced a more efficient 100 Wh design with the Apple Silicon redesign. The 2023 to 2026 A2780 and A2991 stay close to that 2021 layout but may carry slight internal connector changes between M2 and M3 generations. Capacities across the category run about 55 to 95 Wh, so the exact part number is what matters.

Look for your laptop’s model number first, which starts with “A” plus four digits (like A2141) and appears under the Apple menu in About This Mac, or printed on the bottom case. That model number maps to the battery part, since the 2019 unit is A2141, the 2021 is A2485, and the 2023 to 2026 machines are A2780 or A2991. You can also see part numbers such as 020-6380-A or 661-5229 on the existing battery label inside the chassis.

Yes, but it is a high-difficulty job. The battery is strongly adhered to the chassis, so plan to use a kit with specialized adhesive removal tools, like those from iFixit. Some 2019 A2141 batteries are sold as part of a top-case assembly with the pack pre-installed, though the battery can be replaced individually. Take your time, disconnect the battery connector early, and work carefully around the cells. If you are not comfortable with adhesive removal, a repair shop is a reasonable alternative.

Watch for a “Service Battery” warning in macOS, rapid battery depletion, or sudden shutdowns even when the charge reads above zero. You may also notice the laptop running only when plugged in, or the cycle count climbing high in About This Mac under System Report. Since these 100 Wh class packs run 10.8 to 11.26 V, a battery that no longer holds a useful charge is a strong sign it is time for one of the replacements priced from $68.99 to $96.99.
