- ROG Strix G15
- ROG Strix G17
- ROG Strix Scar 15
- ROG Strix Scar 17

Battery health — what we test before shipping
Every battery on our shelf goes through a 5-point test before listing:
- Capacity — we measure actual usable Wh and only ship packs at 95%+ of rated capacity.
- Cycle count — read from the embedded BMS chip; we don't sell anything over 100 cycles.
- Cell balance — all 4-cell internal cells within 50mV of each other.
- Charge/discharge cycle — verified full cycle without thermal anomaly.
- Visual — no swelling, no bulging, no scorched contacts.
Installation — how to swap the battery
Internal 4-cell batteries on modern Asus laptops require opening the back panel (8-12 Phillips screws, sometimes Torx T5). Disconnect the AC adapter, unscrew the panel, locate the battery connector on the board, gently lift the ribbon connector latch, unscrew the battery hold-down screws, lift out the old pack, and reverse the steps with the new one. Total time: 10-15 minutes.
Free installation in shop
If you're in Lahore, bring the laptop to Hafeez Center — installation is free with battery purchase. We'll also calibrate the new pack (full charge → full discharge → full charge) so Windows / macOS reads the correct capacity from day one.
Real-world battery life — what to expect
With this 90Wh pack and balanced Windows / macOS settings (70% brightness, Wi-Fi on, mixed use), expect:
- Web + Office work: 5-7 hours
- Video playback: 6-8 hours
- Code compilation / Photoshop: 2-3 hours
- Gaming or heavy GPU load: 60-90 minutes
These figures match Apple / Dell / HP / Lenovo published specs for the listed models. If your old battery was giving you 2 hours, the new one will restore the original full runtime.

Frequently asked questions
Is this a genuine OEM battery or aftermarket?
Our stock comes in both genuine Asus pulls (tested cells, original casing, often the higher price) and high-grade A-class compatible cells (tested for capacity at 95%+ of rated Wh). Tell us which you want on WhatsApp 0314 4000131 — both carry the same 15-day check warranty.
Will the laptop recognise this battery in Windows / macOS?
Yes — every battery we sell is BMS-flashed with the correct cell-pack ID for the laptop, so Windows / Lenovo Vantage / Dell Power Manager / macOS Battery Health show full information including cycle count and design capacity. No 'plugged in, not charging' driver errors.
How much battery backup will I get on my ROG Strix G15?
With this 90Wh pack at default Windows balanced settings, expect 5-7 hours of mixed-use battery life (web, Office, video). Brightness at 70%, Wi-Fi on, no heavy GPU workload. Gaming or compiling drains in 90-120 minutes — that's normal for any laptop battery this size.
Do I need to take the laptop apart to install the 4-cell battery?
Internal batteries need the back panel removed — typically 8-12 Phillips screws, then disconnect the old battery cable, swap, and reseat. We do free in-shop installation in Lahore if you bring the laptop. Removable 6-cell / 9-cell batteries on older laptops just slide in/out with a latch — no tools needed.
