TREE.NB MacBook Pro A1990 A1953 Replacement Battery — 83.6Wh 11.4V 4‑Cell for 15" Mid 2018/2019

If your MacBook Pro has started shutting down early, showing degraded battery health, or refuses to hold a charge, this TREE.NB A1953 battery offers an OEM-standard alternative without the premium price. Built to match the original A1990 specifications (11.4V, 83.6Wh, 4-cell), the pack includes built-in charge/discharge protection and grade-A cells for consistent performance. This description explains compatibility checks, installation considerations, and what to expect in everyday use so you can decide with confidence.

How do I confirm this battery fits my MacBook Pro?

Compatibility comes down to two quick checks: model identifiers and EMC/part numbers. Verify the MacBook's model identifier in About This Mac or check the underside of the laptop for the A1990/A1953 marking and matching EMC numbers (3215 or 3359).

• Works with MacBook Pro 15-inch (Model A1990) Mid 2018 & Mid 2019.
• Compatible parts: A1953, A1990, EMC 3215, EMC 3359, 820-01095 and related part numbers.
• Supports many retail model codes (MV9xx, MR9xx, MUQH2 variants listed on the product page).
• If unsure, compare the original battery’s label or consult an Apple system report before purchase.

What performance and safety features does this replacement battery offer?

The TREE.NB pack mirrors the original battery’s electrical specs—11.4V and 83.6Wh—so power delivery is consistent with factory expectations. Grade-A cells reduce self-discharge and support fast charging while integrated circuitry protects against overcharge and excessive discharge for safer daily use.

• Rated capacity: 83.6Wh for longer run-time versus worn-out originals.
• Voltage: 11.4V, 4-cell layout matching factory configuration.
• Built-in overcharge and discharge protection circuits for stability.
• Every unit tested at the factory to meet performance standards.

Is installation difficult and what precautions should I take?

Replacing this internal battery requires opening the MacBook Pro bottom case and carefully disconnecting the battery connector. If you haven’t worked on notebooks before, consider watching step-by-step videos or having a technician handle the swap to avoid damaging internal components.

• Turn off the Mac and disconnect power before starting.
• Use the correct screwdrivers and keep track of fasteners and brackets.
• Avoid puncturing the old battery; dispose of it through a certified recycling program.
• If uncomfortable, seek a professional technician to perform the replacement.

How does this battery affect daily use and charging behavior?

Once installed, the replacement should restore the MacBook Pro to near-original battery life under similar workloads. Charging behavior will match the original pack: fast charge supported, and the system reports battery health through macOS. Expect initial calibration cycles where reported capacity stabilizes after several full charge/discharge events.

• Restores typical full-charge run-time comparable to the factory battery.
• Supports rapid charging with protective circuitry active.
• macOS will display charge cycles and battery condition after installation.
• Allow a few cycles for battery meter and system readings to normalize.

Who is this for: This TREE.NB A1953 replacement battery is aimed at MacBook Pro 15" owners (A1990 Mid 2018/2019) who want an OEM-spec, cost-effective battery swap to recover run-time. It’s suited to DIY users comfortable with laptop disassembly, independent repair shops, and anyone who prefers a verified, factory-tested alternative to a worn original. If you need assistance or prefer a hands-off option, professional installation is recommended.
