RDSJK AA-PBMN4VN Laptop Battery for Galaxy Book Pro 15

RDSJK AA-PBMN4VN is a direct-replacement 15.44V Li-ion laptop battery designed to restore full mobile power to compatible Samsung Galaxy Book Pro and Pro 360 15‑inch models.

If your Galaxy Book Pro 360 15 or Galaxy Book Pro 15 has noticeably shorter run time or won’t hold a charge, this RDSJK AA-PBMN4VN battery is built as a drop-in replacement. It uses a 4-cell lithium-ion design rated at 67–68Wh and matches the original equipment voltage, compatible with multiple NP950X/NP950Q model numbers and common Samsung part references. The pack ships new from the manufacturer and includes guidance for initial conditioning to maximize useful cycles.

Which Samsung laptops will this battery work with?

This battery is intended for 15 and 15.6‑inch Galaxy Book Pro and Galaxy Book Pro 360 models. It lists direct compatibility with numerous NP950XDB and NP950QDB/NP950QED variants and replaces several Samsung part numbers used across those lines.

• Compatible series: Galaxy Book Pro 15 and Galaxy Book Pro 360 15/15.6-inch
• Model examples: NP950XDB, NP950QDB, NP950QED and related KB/KA/KC suffix models
• Replaces Samsung part numbers: AA-PBMN4VN, BA43-00398(A), PBMN4VN and equivalents
• Check your laptop’s service label or existing battery part number before ordering

How long does the AA-PBMN4VN battery typically last and how many recharge cycles can I expect?

The pack is rated for up to roughly 500 recharge cycles under normal usage patterns, though real-world lifetime depends on charge habits, temperature and workload. Capacity is specified at 67–68Wh, so after a fresh install you should see runtime comparable to the original factory battery on similar workloads.

• Capacity: 67.0Wh–68.0Wh (4-cell Li‑ion)
• Voltage: 15.44V to match OEM specifications
• Estimated cycles: up to 500 charge/recharge cycles
• Actual run time varies with screen brightness, apps, and connectivity

What should I do when I first install the replacement battery?

Follow the manufacturer’s initial conditioning recommendations to help the battery reach stable performance: partially discharge and recharge in controlled steps rather than full zero-to-full cycles. This brief conditioning routine can improve the battery’s calibration and early capacity results.

• Initial cycle: discharge to about 5% (not 0%), then charge to 95%
• Repeat the 5% → 95% cycle 3–4 times for best initial calibration
• Use the laptop on AC power while updating firmware or large files after install
• Avoid extreme temperatures during first few cycles

Is this battery safe and what installation tips should I follow?

The AA-PBMN4VN is a factory-new Li‑ion pack built to match the original Samsung power profile; safe installation practices minimize risk. Always power down the laptop, remove external power, follow anti-static precautions, and secure connectors to avoid damage.

• Power off and unplug before opening the chassis
• Handle the pack gently and avoid puncturing the cells
• Confirm connector alignment and screw torque to prevent stress
• Recycle your old battery responsibly according to local regulations

Who is this for: This replacement battery suits owners of Samsung Galaxy Book Pro 15 and Galaxy Book Pro 360 15/15.6-inch laptops who need to restore portable runtime without sourcing OEM inventory. It’s appropriate for technicians, small-business users, and consumers comfortable opening their laptop for a straightforward battery swap—especially when the original pack shows reduced capacity or will not hold charge.
