Compatibility — which laptops does this battery fit?
This 43Wh 2-cell internal battery is a direct OEM replacement for the following Microsoft laptops:
- Surface Pro 7
- Surface Pro 6
- Surface Pro 5 (2017)
Match the OEM part number on the sticker of your current battery before ordering. If your old battery part number isn't on this list but the laptop is, message us on WhatsApp 0314 4000131 — there are often three or four interchangeable part numbers per chassis.
How this battery compares to aftermarket options
Many aftermarket batteries claim compatibility, but few match the original Microsoft cell quality. Our stock is genuine OEM pulls — bench-tested for capacity, cycle count, and safety. Unlike generic packs, these maintain accurate fuel gauge readings in Windows, so you never get sudden shutdowns at 15% charge. For the same price as a cheap clone, you get a battery that will actually last 400-600 full cycles. We also stock high-grade A-class compatible cells if you prefer a brand-new option — just ask Sayam on WhatsApp 0314 4000131.
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 2-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.
This bench-testing process ensures you get a battery that's ready to perform — not a gamble. We've seen too many customers bring in laptops with swollen cells from unsafe clones; that's why we only sell tested, verified packs.
Installation — how to swap the battery
Internal 2-cell batteries on modern Microsoft 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, Gulberg III — installation is free with battery purchase. We'll also calibrate the new pack (full charge → full discharge → full charge) so Windows reads the correct capacity from day one. For customers in Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, or Sialkot, we offer free nationwide delivery via TCS / Leopards — order through WhatsApp and we'll ship the same day.
Real-world battery life — what to expect
With this 43Wh 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. For best longevity, avoid keeping the laptop plugged in at 100% all day; let it cycle between 40% and 85%.
What's in the box?
You receive the battery only — no screws, no tools. Use the screws from your old battery. If you need a set of replacement screws, just ask Sayam when you order; we include them free with any battery purchase from nnlaptops.com.

Frequently asked questions
How long will the new battery last?
A fresh quality cell-pack should give you 400-600 full charge cycles (about 2-3 years of daily use) before noticeable capacity drop. Avoid leaving the laptop plugged in at 100% all day — keep it cycling between 40% and 85% for longest cell life.
How much battery backup will I get on my Surface Pro 7?
With this 43Wh 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.
Is this a genuine OEM battery or aftermarket?
Our stock comes in both genuine Microsoft 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 30-day check warranty.
Will the laptop recognise this battery in Windows?
Yes — every battery we sell is BMS-flashed with the correct cell-pack ID for the laptop, so Windows shows full information including cycle count and design capacity. No 'plugged in, not charging' driver errors.
