Asus A4I X550A 44Wh Battery (also known as A41-X550 / A41-X550A) — Buyer’s & Compatibility Guide

Quick Facts

• Names & aliases: Asus A4I X550A 44Wh, commonly labeled A41-X550 / A41-X550A.
• External/removable design: No need to open the bottom case. Release the rear latches and lift the pack out.
• Wide coverage: Works with many X450 / X550 / R510 / F550 / K550 / P550 (Pro) variants and regional SKUs.
• Capacity label: 44Wh (typically 4-cell). You may see 14.4V or 14.8V printed; that’s normal for this family — match by label and shape.

How to Confirm Compatibility (3 steps)

1. Check your old battery’s label: If it shows A41-X550 or A41-X550A, you’re in the right family.
2. Check shape & contacts: The outer housing, latch notches, and contact location should match your original.
3. Match your laptop SKU: Look for your exact model below (including regional suffixes like DM/T, XO, XX, etc.).

Installation (External/Removable)

1. Shut down the laptop and unplug the AC adapter.
2. Flip the laptop over. Slide the two battery latches to the “unlock” position.
3. Lift the battery pack out; seat the new pack in the same orientation until it clicks.
4. Slide latches back to “lock,” then power on.

Tip: After replacement, a full charge–discharge cycle can help the OS re-calibrate the battery meter.

Charging & Care Tips

• After installation, do 1–2 full charge/discharge cycles to re-calibrate the OS battery gauge.
• If you use the laptop plugged in most of the time, cycle the battery to ~20–30% and recharge every 2–4 weeks.
• For storage, keep ~40–60% charge in a cool, dry place; avoid heat and heavy pressure.

FAQ

Q1: Are A41-X550 and A41-X550A different?

They’re part of the same battery family used across X450/X550 series. Match by label, shape, and latch/interface.

Q2: My old battery shows 14.4V — can I use one labeled 14.8V?

Both labels appear in this family due to cell nominal voltage notation. Match by label family and housing; they’re typically interchangeable in this series.

Q3: Can I replace a different Wh version (e.g., 37Wh/48Wh) with 44Wh?

As long as the housing and latching/contacts are the same, it will fit. Wh affects runtime, not fit.
