HP Laptop Battery Replacement Cost UK 2026 — Pavilion, ENVY & EliteBook Prices
Direct answer: HP laptop battery replacement in the UK costs from around £44.95 on an older Pavilion 15 up to £119.95 on a current Spectre x360, with most Pavilion and Envy packs at £69.95–£89.95 and EliteBook at £79.95–£99.95. Internal batteries in newer Spectre and ENVY models need more disassembly than the removable packs in older Pavilions, which is part of the spread. Every price below is from our live price list, and every battery carries a 27-month guarantee. If your pack is swollen or bulging, treat it as urgent — stop using the laptop and send it promptly.
A tired HP battery is one of the highest-value repairs on any laptop: a machine that dies after twenty minutes, shuts down without warning, or will not run off the charger at all is almost always a perfectly serviceable computer saddled with a worn-out cell. The job is quick, the part is cheap relative to the machine's value, and the 27-month guarantee means the new pack outlasts the rest of the laptop's useful life. The exact per-model price is below, along with the one detail that decides the labour — whether your HP uses a pack that slides out of the base or an internal cell secured behind the bottom cover. Start at our HP laptop repair cost hub for the full picture, and see our charging port guide if your HP won't charge at all (a different fault, with a different price).

Swollen HP battery: what to do
A swollen or bulging battery is a genuine safety issue, not a wear-and-tear inconvenience. If your HP's trackpad is lifting, the chassis is bowing, or the laptop rocks on a flat desk, the lithium cell inside is expanding as it degrades — and a punctured or overheated swollen cell can vent or catch fire. The correct response is to stop using the laptop immediately, do not attempt to charge it, and do not try to lever the pack out yourself. Switch it off, leave it on a non-flammable surface away from soft furnishings, and send it for a prompt replacement. We remove and replace swollen packs safely, every day.
When you post a swollen-battery HP, pack it so the chassis cannot be squeezed in transit — a rigid box with the laptop held centrally by corner padding, not bubble-wrap packed tight around it. Our HP repair by post guide covers safe packing in detail.
Signs your HP battery needs replacing
- Won't hold charge — runtime has collapsed to well under an hour, or the percentage drops in sudden jumps.
- Unexpected shutdowns — the laptop powers off without the low-battery warning, then sometimes restarts when plugged in.
- Won't run off the charger — works on mains, dies the moment you unplug.
- HP Support Assistant warning — the built-in battery health check flags a weak or faulty cell (a reliable consumer signal).
- Visible swelling — a lifting trackpad, a bowing base, or the laptop no longer sitting flat.
Internal vs removable HP batteries
HP's range splits into two designs. Older Pavilion and some business models use a removable pack that slides out of the base — a faster, cheaper swap because no chassis disassembly is needed. Newer Pavilion, ENVY, EliteBook and all Spectre x360 models use internal packs, secured inside with adhesive and screws; on the slimmest Spectres the pack is glued into the lid or base, which is the labour that pushes those repairs higher. The cell itself is similar across the range; the difference is the time and care needed to reach it.
On a glued-shut Spectre, lifting the pack out in one piece is the whole job — soft heat, a plastic spudger and patience, since a torn cell or a cracked lid is what rushing buys you. The fresh OEM-grade cell is bonded back in, the gauge is re-taught so it stops echoing the old pack's numbers, and the machine is load-tested before it is closed up. The 27-month guarantee covers the cell and the labour.
How we test before we swap
Not every "bad battery" symptom is the battery. Before we condemn a pack we bench-check the machine: a multimeter test on the old cell confirms whether it is genuinely depleted or whether a charging-port or board-level fault is starving it of power. A laptop that "won't charge" is sometimes a worn USB-C port, not the battery — and replacing a perfectly good cell would waste your money. That is why diagnosis comes first and the figure we confirm is the figure you pay. Diagnostics are free on standard battery work.
What a battery replacement involves
The job divides neatly by era. On an older Pavilion with a slide-out pack there is barely a teardown to speak of — flip the laptop, work the two retaining latches, and the worn pack lifts clear of the base; the fresh cell drops into the same bay, the latches click home, and the next boot shows the restored capacity. A modern Pavilion, ENVY or EliteBook hides its cell inside, so we lift the base panel, free the battery lead from the board, release the cell from the screws or clips pinning it into its tray, and bed the new OEM-grade pack down in its place. Then we wipe the gauge's stored history so it learns the real cell in front of it instead of parroting the dead one's last reading.
The Spectre x360 is the careful one. On the thinnest convertibles the pack is bonded into the base, and a degraded HP cell that has begun to push the trackpad up is precisely the sort that must never be flexed or prised — so removal is gentle warmth, a slim spudger walked under the adhesive, and a slow, even peel that keeps the cell flat the whole way out. With the old pack clear and the residue scraped back, the new cell is seated, re-secured, and run through a full discharge under genuine load to prove its rated runtime before the base ever goes back on. The 27-month guarantee covers the cell and the work that went in around it.
Making the new battery last
A replacement cell is only as good as how it is treated afterwards. A few habits add years to an HP battery: avoid leaving the laptop pinned at 100 percent on the charger for weeks on end (HP's own battery-care limit, where fitted, helps here); let it cycle down to roughly a quarter rather than trickle-charging forever; and keep the machine away from sustained heat — a clogged heatsink cooking the cell from above ages a battery faster than any charge pattern. If your HP runs hot, a heatsink clean and repaste is the single best thing you can pair with a battery swap. See our common HP faults guide for the overheating detail.
OEM-grade vs aftermarket HP batteries
Every pack we fit is an OEM-grade cell matched to HP's original capacity and voltage, and we name the part before a screwdriver touches the laptop. A bargain aftermarket cell is tempting, but they tend to read short on capacity from the first charge, fade quicker, and bloat sooner — and on a glued Spectre a second bloat means paying for that whole delicate teardown twice. Buying once on an honest cell is simply the cheaper road. Our parts-grade guide sets out the difference.

Frequently asked questions
How much does HP Pavilion laptop battery replacement cost?
A Pavilion 15 battery is around £69.95 for current internal models, with older removable packs from £44.95–£54.95; the Pavilion Plus 14 sits at £89.95. Each price is published above and carries a 27-month guarantee.
Is a swollen HP laptop battery dangerous?
Yes. As the cell degrades it can vent or ignite if it is pierced or left to overheat. Switch the Pavilion off, keep it away from the charger, and get it to us promptly — safely removing bulging packs is daily bench work for us.
My HP battery won't charge — is it the battery or the port?
Not always the battery. A worn USB-C charging port or a board-level charging fault can starve a healthy cell of power. We bench-check with a multimeter before condemning the pack, so you only pay for the repair you actually need.
How long does an HP laptop battery last before it needs replacing?
Most lithium packs show meaningful wear after roughly 500–1000 full charge cycles — typically three to five years of daily use. The built-in HP Support Assistant battery health check will flag a weak cell before it fails outright.
Will a replacement HP battery last as long as the original?
Matched to HP's original capacity, an OEM-grade cell returns runtime and service life on a par with the pack that left the factory. It is the cut-price aftermarket cells that disappoint — short on capacity, quicker to fade — so we fit the honest part and stand behind it with the 27-month guarantee.
Can I replace my HP laptop battery myself?
On a vintage Pavilion with a slide-out pack, yes — the latches do the work. The internal and glued Spectre, ENVY and EliteBook cells are another matter: a full teardown with real puncture risk once a pack has begun to swell, which is why the bench is both the safer and the quicker option.
