Battery health — what we bench-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 cells within 50mV of each other.
- Charge/discharge cycle — verified full cycle without thermal anomaly.
- Visual — no swelling, no bulging, no scorched contacts.
This rigorous bench-testing ensures you get a battery that performs like new. Whether you're in Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, or Sialkot, we ship only units that pass our quality checks.
Installation — how to swap the battery
Internal 4-cell batteries on modern HP 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 Shop 66A, 3rd Floor, Hafeez Center, Gulberg III, Lahore — 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 48Wh 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 the HP ProBook 450 G5 price in Pakistan 2026, this Rs. 9,499 battery offers unbeatable value.
Why choose this battery over cheaper alternatives?
Many online sellers offer non-genuine batteries at lower prices, but they often use inferior cells that degrade within months. Our batteries are either genuine HP pulls or high-grade A-class compatible cells — both bench-tested for capacity at 95%+ of rated Wh. We've seen too many laptops ruined by swollen knockoffs; that's why we personally test every unit. You get peace of mind backed by our 30-day check warranty and a shop you can visit in Hafeez Center.
How to maximize battery lifespan
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. Also, keep the laptop in a cool, ventilated area; heat is the number one enemy of lithium cells.

Warranty — what you're protected against

Frequently asked questions
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.
How much battery backup will I get on my ProBook 450 G5?
With this 48Wh 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 HP pulls (tested cells, original casing) 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, and both are bench-tested before listing.
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.
