- Latitude 7480
- Latitude 7490

- Latitude 7280
- Latitude 7290
Match the OEM part number on the sticker of your current battery before ordering.

We can confirm compatibility with your exact model.
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.
If you're in Lahore, you can come to Hafeez Center and see the test results live on our diagnostic tool. For buyers in Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, or Sialkot, we share a short video of the test via WhatsApp before dispatch.
Installation — how to swap the battery
Internal 4-cell batteries on modern Dell 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. If you've never done it before, watch a YouTube guide for your model—or just bring it to us.
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. Our owner Sayam will personally guide you through the process and answer any questions.
Real-world battery life — what to expect
With this 60Wh 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 Dell 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 heavy users, we recommend enabling battery saver mode to extend life further.

Frequently asked questions
Is this a genuine OEM battery or aftermarket?
Our stock comes in both genuine Dell 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. The price listed is for the genuine DM3WC pull, which is exactly what Dell would supply.
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. Our genuine DM3WC battery has a built-in BMS that manages charging safely.
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. We verify this during our bench test.
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. If you're not comfortable, come by Hafeez Center and Sayam will do it for you.
