FAQ
Q1: Will this 99.9Wh BTY-M6J fit my MSI Stealth laptop?
A: Yes, if your original battery label reads BTY-M6J and your laptop is an MSI Stealth GS63 / GS63VR / GS73 / GS73VR (MS-16K2 / MS-17B1) model listed above. Always confirm the printed model before ordering.
Q2: How much more run-time does 99.9Wh give me?
A: 99.9Wh is the top-tier capacity for this series, giving the longest possible unplugged session. Under mixed gaming/productivity use you can expect noticeably more run-time than a standard 64.98Wh pack.
Q3: Is a high-capacity battery safe for my MSI?
A: Yes. The pack uses the same voltage and connector specification as the original and is protected by an integrated BMS with over-charge, over-discharge and short-circuit protection.
Q4: How fast is delivery and what warranty applies?
A: Ships from UK stock for fast domestic delivery, covered by a 1-year warranty with free replacement on DOA or in-warranty failure.
