HP EliteBook 840 G9 Battery Replacement Cost Pakistan
The 840 G9 (12th-gen Intel, launched 2022) is HP's redesigned EliteBook 840 — slimmer chassis, a new 51Wh battery, and a different connector from the G5-G8 generation it replaced. If you searched using a price from an older EliteBook thread or forum post, it's probably quoting the earlier 56Wh part, which is a different price and won't physically connect on a G9. Most owners here are 1-3 years into ownership of a corporate-issued unit and starting to notice the battery isn't lasting a full workday anymore.
Pricing in Pakistan is Rs. 4,500 – 5,500 for a Tier-1 OEM-equivalent 51Wh pack, or Rs. 5,500 – 6,500 for a genuine HP-branded battery — slightly higher than the older G5-G8 generation despite the smaller Wh rating, reflecting both newer part costs and lower current supply volume in the Lahore market compared to the higher-turnover older generation. We confirm your exact generation via the base sticker or serial number before ordering, since fitting a G5-G8 part on a G9 simply won't connect.
Cost breakdown
oem
- price
- Rs. 5,500 – 6,500
- notes
- Genuine HP-branded 51Wh battery matched to the G9's redesigned connector. Preferred for corporate assets tracked under HP's genuine-parts policy, and generally the safer choice while G9 part supply is still building up in the local market.
compatible
- price
- Rs. 4,500 – 5,500
- notes
- Tier-1 OEM-equivalent 51Wh pack matched to the G9's specific connector. We verify fitment before ordering given this generation is newer and less standardised in the local aftermarket than G5-G8 parts.
labour
Included in the price above — no separate callout or labour fee. Bench time: 30-90 minutes (screw-mounted pack, no adhesive).
warranty
15-day repair warranty on the labour plus a 30-day battery warranty on the new pack itself — if it fails through no fault of your own (drops, spills and physical damage excluded) within 30 days, we replace it again at no charge.
Signs your battery needs replacement
- ▲Runtime has fallen well short of the original all-day rating within the first 1-3 years of ownership
- ▲HP Support Assistant's Battery Check under Component Tests reports a fail or a health score below the “Good” range
- ▲Windows shows “Consider replacing your battery” with a battery warning icon
- ▲The laptop shuts down unexpectedly under video-call or multitasking load, even with charge shown as remaining
- ▲The base near the trackpad or keyboard deck feels slightly raised — check for swelling; the G9's slimmer chassis shows this faster than the thicker G8
Turnaround time
Walk-in
Same day for walk-ins — most Windows business-laptop battery swaps take 30-90 minutes once you approve the quote, because the pack is screw-mounted rather than glued.
Courier from other cities
5-9 working days round-trip from Lahore, Sialkot, Gujranwala, Faisalabad, Islamabad, Rawalpindi or Sargodha; 7-13 working days from Karachi, Multan, Peshawar, Hyderabad, Abbottabad or Bahawalpur; 9-16 working days from Quetta or Sukkur. That covers courier there, free diagnosis within 24 hours of arrival, the repair itself, and courier back — we confirm your exact date on WhatsApp once diagnosis is done.
Frequently asked
Can I replace the 840 G9's battery myself?
More involved than the G8 — the G9's slimmer redesign means a tighter internal layout and, on some configurations, a partial adhesive strip alongside the retaining screws. It's still far easier than a MacBook, but confirm you have the correct G9-specific pack before attempting it yourself, since the connector changed from G8. If you're not confident, our same-day bench turnaround removes most of the incentive to DIY.
Does this repair void any remaining HP warranty?
If your 840 G9 is a recent purchase still under HP's standard business warranty (commonly 3 years on-site), check coverage via HP Support Assistant or hp.com/support with your serial number before using third-party repair to keep that warranty intact. If it's already lapsed, our own 15-day repair plus 30-day battery warranty applies.
How do I check battery health and cycle count on the 840 G9?
HP Support Assistant's Battery Check (My Devices > Component Tests) reports a pass/fail plus health percentage. Windows' powercfg /batteryreport also works, showing Design Capacity vs Full Charge Capacity and a 30-day history. Run either before booking so you have a concrete number, not just a feeling that battery life has dropped.
Will a G8 battery fit my G9, or vice versa?
No — HP changed both the physical connector and the cell capacity (56Wh 3-cell on G5-G8 versus 51Wh on G9-G10) as part of the redesign. The two are not interchangeable even though they look similar from outside the chassis. Always confirm your exact generation via the base sticker or serial number before ordering a replacement, from us or anywhere else.
Is it worth replacing the battery on a relatively new 840 G9?
Yes, if the health check confirms genuine degradation rather than a software or power-setting issue — a 12th-gen Intel business laptop has a long useful life ahead, and Rs. 4,500 – 5,500 for a battery is a small fraction of its current value. If the health percentage still reads high but you're seeing poor runtime, check Windows power plan settings and background apps first; we do this for free during diagnosis before quoting a replacement you might not need.
