HP sells more laptops in India than any other brand, and battery replacement is the most common service call we handle for HP laptops. The complication compared to other brands is HP’s battery code system — HS04, JC04, LA04, HT03XL, HW03XL, MG04XL. These codes are not interchangeable, and the wrong battery will either refuse to charge past a certain percentage or trigger a “Battery not recognized” warning even when it physically fits. This guide explains the codes, the costs by model, and what the replacement process actually involves.
Why HP battery codes matter — HS04, JC04, LA04, HT03XL, HW03XL explained
Every HP battery has a part code stamped on the label visible through the base panel. These codes encode the cell count, capacity, and connector type that HP’s embedded controller (the small chip on the motherboard that manages charging) is programmed to expect.
HS04 (and its 3-cell sibling HS03): a 4-cell lithium-ion battery producing approximately 41 Wh (watt-hours, the unit of energy capacity), used in Pavilion 14 and 15 models from roughly 2015 to 2019. The “HS” prefix denotes the Pavilion standard series of that generation.
JC04 (and JC03): the successor for Pavilion 14 and 15 models from 2019 to 2022. Same 41–41.6 Wh rating but with a revised connector and slightly updated protection circuit. A JC04 will not charge correctly in a laptop designed for HS04, and vice versa — the controller rejects the handshake.
LA04 (and LA03): an earlier Pavilion 14/15 4-cell variant from 2013–2015. Still in circulation because many users keep these machines for light web-browsing tasks.
HT03XL: a slimmer 3-cell battery used in the Pavilion x360 and Envy x360 convertible (2-in-1) laptops. The “XL” suffix indicates an extended-length cell pack designed to fit the convertible chassis. Despite similar voltage, HT03XL is physically different from HS04 — the connector, cable length, and mounting points differ completely.
HW03XL: a higher-capacity 3-cell battery used in Envy 13, Envy 14, and Victus 15 models. Higher Wh rating (41.9 Wh) in the same slim form factor as HT03XL.
MG04XL: the premium 4-cell battery for Spectre x360 13 and 14. Highest capacity in the non-gaming HP lineup.
The rule is simple: always match the code printed on your existing battery. If you cannot read the code, bring or send the laptop to us — we verify from the service tag before sourcing the cell. See the full HP repair hub for model-specific notes.
HP Pavilion 14/15 battery cost — the most common job
Pavilion battery replacement accounts for the majority of HP battery calls in India. The Pavilion 14 and 15 series (G3 through G8 generations) use either HS04, JC04, or LA04 depending on year. These are among the most straightforward laptop battery replacements to carry out: 10 screws on the base panel, one cable connector, and the battery module lifts out cleanly.
Cost ranges from ₹2,000 to ₹4,200 depending on the specific code (LA04 is cheaper to source; JC04 costs slightly more because it is newer). The battery replacement service page covers the standard process. Expect a 30-day warranty on any cell we fit. Exact quote confirmed over WhatsApp before work begins — pricing depends on cell grade and your model year.
One common scenario: users buy a compatible cell online that “fits” the connector but is the wrong code. The laptop accepts it but Windows reports 0% capacity or the battery drains in 30 minutes. Whenever you buy a Pavilion battery anywhere, verify the code matches your existing battery label before accepting the job is done.
HP EliteBook battery cost — business-grade cells at a higher starting price
HP EliteBook laptops (840, 850, 1040, and x360 EliteBook lines) use business-grade cells with higher cycle ratings (the number of full charge/discharge cycles before capacity drops below 80%). Standard consumer cells are rated for 300–500 cycles; EliteBook cells are rated for 1,000 cycles.
The consequence is a higher sourcing cost: ₹3,200 to ₹6,000 for EliteBook batteries. The positive flip side is that a well-maintained EliteBook battery genuinely lasts 3–5 years in business use where it is not abused with continuous 100% charge. If your EliteBook battery is failing before year 3, suspect that the machine has been left plugged in at 100% continuously — activating HP’s Battery Care function in UEFI (the firmware settings screen) limits charge to 80% and dramatically extends cell life.
EliteBook batteries in slim models (1040, EliteBook x360) are harder to access than Pavilion batteries — expect a longer service time and slightly higher labour component. The HP service hub has model-specific disassembly notes for EliteBook variants.
HP OMEN and Victus gaming battery cost — large capacity cells
OMEN 15 and 16 gaming laptops use large 6-cell batteries (70–83 Wh) to sustain gaming loads. The Victus 15 and 16 use a mid-size 3-cell HW03XL variant. Gaming laptop batteries face heavier discharge cycles because GPUs (graphics processing units — the chip that handles game rendering) draw significant power during play.
OMEN battery replacement costs ₹3,500 to ₹6,500 depending on the specific OMEN generation and cell capacity. Victus batteries run ₹3,000 to ₹5,500. One note specific to OMEN: the bottom panel has more screws than Pavilion and a rubber strip over two hidden screws near the vents — missing these screws can damage the panel. We advise against DIY on OMEN unless you have done it before.
Gaming batteries in India also tend to show faster degradation because users often play plugged in while the battery is simultaneously being charged to 100% — heat from the GPU compounds the lithium-ion degradation that already occurs at full charge.
HP Spectre x360 and Envy battery cost — slim cells, premium pricing
Spectre x360 and Envy (non-x360) laptops use the MG04XL and HW03XL batteries respectively, in a flat pouch form factor glued to the inside of the chassis. Unlike the Pavilion where the battery is a rigid module you unplug and lift out, these batteries have a thin adhesive strip holding them flat against the bottom case. Removing them without the correct heat gun technique risks puncturing the cell, which is a safety event with lithium-ion.
We never rush Spectre or Envy battery replacements. The process: heat the base to around 60°C (measured with a thermal probe, not estimated), use a plastic pry tool to gently lift the battery along the adhesive edge, disconnect the flat cable connector, and fit the new cell with fresh adhesive tape. Cost ₹3,500 to ₹6,000 for Spectre x360. Envy 13 and 14: ₹3,000 to ₹5,500.

Signs your HP battery needs replacement
Not every HP battery problem requires immediate replacement. Here is how to read the signals:
Swelling (palmrest or base lifting): This is not optional — the battery must be removed immediately. A swollen lithium-ion cell has gas accumulating inside the pouch (a process called electrolyte decomposition). The swollen cell can rupture under pressure or heat, causing a fire. Stop using the laptop, do not place it in a bag or on fabric, and arrange professional removal. This is the one scenario where we tell customers to courier the machine to us even from outside Hyderabad.
Draining faster than expected: If the battery that used to last 4 hours now lasts under 90 minutes at similar usage, it is at or below 50% capacity. Run the Windows Battery Report (Command Prompt → powercfg /batteryreport) to see Design Capacity vs Full Charge Capacity. Below 60% of Design Capacity = replace now. 60–75% = plan to replace within 3 months.
Not charging past a percentage: If the battery stops at 80%, that may be HP’s Battery Care function intentionally limiting charge to prolong cell life — check your settings before assuming a fault. If it stops at an arbitrary number (37%, 62%) and won’t move, a charging circuit fault or failing cell is likely.
Battery not recognized warning: Windows shows a red X on the battery icon and “Consider replacing your battery.” This is HP’s embedded controller reporting that the cell’s capacity has fallen below a threshold. The threshold is conservative — the battery may have 3–6 months of usable life left, but at degraded performance.
The battery drains fast service page covers the diagnostic sequence in detail.
Genuine vs compatible cells — what we use and why
HP OEM (Original Equipment Manufacturer) batteries are assembled by Dynapack or Simplo Lenovos (the licensed suppliers for HP). Genuine OEM cells carry the HP part number, matching firmware handshake data, and typically a 1-year manufacturer warranty at the cell level.
Quality-compatible cells use the same Samsung SDI or Panasonic cell chemistry inside a new pack with a rewritten protection circuit board (PCB) that matches HP’s handshake. The cell itself is comparable quality; what varies is the protection circuit. A properly built compatible battery from a verified supplier performs within 5% of OEM capacity and lasts comparably.
The risk category is ultra-cheap cells (typically under ₹800 online) that use unknown cell chemistry and a minimal protection circuit. These can overheat, overcharge, or fail to cut off properly during a short circuit. We do not use these. We source traceable compatible cells from established suppliers with a verified cell pedigree, and every battery we fit carries our 30-day warranty.
When you need an HP OEM battery specifically (e.g., for corporate asset compliance), we can source those too — at a higher cost reflecting the HP part mark-up. WhatsApp us the model and we will quote both options.
DIY battery swap — which HP models allow it and which do not
The short answer: Pavilion 14/15 G3 through G7 series are DIY-friendly. Everything with a glued or pouch-style battery is professional-only.
DIY-feasible HP models: Pavilion 14/15 (G3–G7), HP 15s, HP 14s, HP 245/255 G-series (budget business range). These have a Phillips-head screw base panel, accessible battery connector, and no adhesive. You need a PH0 or PH1 screwdriver, a plastic pry tool, and 20–30 minutes.
Professional-only HP models: Spectre x360 (all generations), Envy x360 (13-inch and 15-inch), Envy 13 and 14, OMEN 16 (the 15 is borderline), EliteBook x360, EliteBook 1040, HP Dragonfly. These use either glued flat-pouch batteries requiring heat removal, or have the battery routing under the motherboard in the OMEN 16’s case (the board must be lifted to access the battery connector).
If you are unsure which category your HP model falls into, WhatsApp us the model number (printed on the base sticker or visible in System Information) and we will tell you honestly whether it is DIY-safe before you open anything.
What we do at our workshop
Every HP battery replacement at our bench follows a fixed sequence. First, we verify the battery code from the existing cell before ordering anything. Second, for models with adhesive batteries, we test peel-force with a probe before applying heat — newer adhesive formulations require less heat. Third, we bench-test the replacement cell at 20%, 50%, and 80% charge before closing the case, verifying that the HP embedded controller recognises the cell correctly and that Windows reports the expected Design Capacity.
We then run the machine for 15 minutes under light load to confirm there is no thermal anomaly at the battery (a rare sign of a defective cell). Only after all three checks pass do we close the case and return the machine. The ₹149 visit charge covers the in-home diagnostic version of this same sequence if you prefer we come to you — we bring the likely replacement cells for common Pavilion models so the job is done in one visit for most cases.
For OMEN, Spectre, and EliteBook variants, we typically need to take the machine to our workshop for the cell removal process. Turnaround is same-day for most models.
