Full specifications

Compatibility — which laptops does this battery fit?

This 42Wh 3-cell internal battery is a direct OEM replacement for the following HP laptops:

• EliteBook Folio 1040 G3
• EliteBook Folio 1040 G2
• EliteBook Folio 1040 G1

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 — there are often three or four interchangeable part numbers per chassis.

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 3-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 3-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 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 42Wh 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.

Warranty — what you're protected against

Every battery carries our 30-day check warranty.

No questions asked within the warranty window.

Frequently asked questions

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.

Do I need to take the laptop apart to install the 3-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 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.

Is this a genuine OEM battery or aftermarket?

Our stock comes in both genuine HP 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.

Why this battery is a smart investment

At Rs. 12,699, this HP EliteBook Folio 1040 G3 / 1040 G2 42Wh 3-Cell Battery (BL06XL) offers exceptional value for anyone looking to restore their laptop's original run time without spending on a brand-new OEM pack. A new HP battery can cost over Rs. 20,000, while our tested genuine pulls deliver the same performance at a fraction of the price. Each unit is bench-tested to ensure it meets or exceeds 95% of its rated capacity, with cycle counts typically under 100. This means you get reliable power for daily work, whether you're in Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, or Sialkot.

Real-world performance you can count on

We understand that a battery is the heart of your laptop's portability. That's why we hand-pick and test every battery at our shop in Hafeez Center, Lahore. Our testing process includes a full charge-discharge cycle to verify capacity, cell voltage balance, and BMS communication. This ensures that when you install the battery, your HP EliteBook will report accurate charge levels and cycle count — no surprises. Whether you're a student attending online classes, a professional working on the go, or a gamer needing uninterrupted sessions, this 42Wh pack will keep you productive.

How it compares to aftermarket alternatives

Many aftermarket batteries claim compatibility but often suffer from poor cell quality, unmatched firmware, or shorter lifespan. Our stock consists of genuine HP pulls from lightly used EliteBooks, so you get the exact same cells and casing as the original. While new compatible batteries from brands like Green Cell or Laptop Battery Shop may cost slightly less, they rarely match the build quality and reliability of genuine HP parts. With our 30-day check warranty, you can test the battery risk-free — if it doesn't meet your expectations, we'll take it back.
