USAbatteries.com stocks 3 compatible replacement batteries for the HP 13 series. Replacement batteries in this category are priced at $57.99.

HP’s 13-inch laptops have anchored the company’s portable lineup since around 2010, packing full performance into a small footprint. The line is built for students, travelers, and business professionals who want a slim machine they can carry all day. It spans more than a decade of releases across consumer and premium families, with designs ranging from everyday Pavilion models to luxury Spectre convertibles.

HP 13 batteries are lithium-ion (some sub-series use lithium-polymer packs) with capacities that generally fall between the low 40s and low 60s of watt-hours depending on the generation and model family. Cell counts and part numbers vary by sub-series and year, so the exact pack is tied to your specific product family. For example, an Envy 13 from 2016 to 2018 uses a VR03XL while a 2020 or later Envy 13 uses a BN03XL, so two laptops in the same family can take completely different batteries and you must match your exact model.

Always confirm your exact model number and the part number printed on your current battery before ordering.

Frequently Asked Questions

What battery does the HP 13 use?

The HP 13 uses an internal lithium-ion battery, and the exact part depends on your sub-series and year. Pavilion 13 models commonly use PG03XL or AL04XL, Envy 13 models use BN03XL (2020 and newer) or VR03XL (2016 to 2018), and Spectre 13 models use packs like BF04XL or SP04XL. Capacities run from the low 40s up to about 61 watt-hours. Replacement batteries in this category are priced at $57.99. Match the part number printed on your current battery to be sure.

How do I find the right battery for my HP 13 model?

Start with your full model number, then confirm the part number printed on the existing battery once you open the bottom case. HP packs follow patterns like a four-letter code plus XL (for example VR03XL or BN03XL) or an HSTNN hardware code. Knowing your sub-series and year narrows it fast, since a 2016 Envy 13 takes VR03XL while a 2020 Envy 13 takes BN03XL. The printed part number is the most reliable match, so check it against the listing before ordering.

How much does an HP 13 replacement battery cost?

HP 13 replacement batteries in this category are priced at $57.99. The price is consistent across the lineup, so whether you have a Pavilion 13 using PG03XL, an Envy 13 using BN03XL, or a Spectre 13 using SP04XL, you are looking at the same $57.99. The thing that changes is which specific part you need, not the price, so focus on matching your exact part number rather than shopping by cost.

Are HP 13 batteries interchangeable?

No, HP 13 batteries are generally not interchangeable across sub-series or even across years within the same family. Battery designs are model-specific, so a Pavilion 13 pack will not fit an Envy 13 or Spectre 13. Even inside one family the part changes, as the Envy 13 uses VR03XL on 2016 to 2018 models and BN03XL on 2020 and newer ones. Always match the four-letter prefix and XL suffix (or the HSTNN code) to your exact laptop.

What differs between the HP 13 sub-series batteries?

The differences come down to part number, capacity, and physical fit. Pavilion 13 typically uses PG03XL or AL04XL in the 41 to 60 watt-hour range. Envy 13 uses VR03XL or BN03XL, generally 43 to 53 watt-hours. Spectre 13 uses BF04XL, SP04XL, or HSTNN coded packs that run from 43 up to about 61 watt-hours for all-day power. Each pack is shaped for its specific chassis, which is why a Spectre battery will not drop into a Pavilion.

Where do I find the battery part number?

The part number is printed on a label on the battery itself, which means you will usually need to remove the bottom case to read it. Look for a four-letter code followed by XL (for example PG03XL, VR03XL, or SP04XL) or an HSTNN hardware code like HSTNN-IB8R. You will need a small Phillips or Torx screwdriver to open the chassis. Cross-reference that printed code with the listing to confirm you have the correct pack before ordering.

Can I replace the HP 13 battery myself?

Yes, in most cases. HP 13 laptops use internal batteries, so you will remove the bottom case with a small Phillips or Torx screwdriver, disconnect the old pack, and install the matching replacement. Confirm the printed part number first, such as BN03XL on a newer Envy 13 or BF04XL on an ultra-slim Spectre. Step-by-step guides on repair platforms like iFixit walk through your specific model. Work carefully around the cable connector and seat the new battery fully before reassembling.

What are the signs the HP 13 battery needs replacing?

Common signs include a sharp drop in runtime, the laptop shutting down at higher charge percentages, or the battery no longer holding a charge. You may also see the system stay pinned near 0 percent or refuse to run unplugged. If your once all-day Spectre 13 (with a pack up to about 61 watt-hours) now lasts an hour, that points to a worn battery. Checking the part number, such as VR03XL or PG03XL, then ordering the matching $57.99 replacement is the next step.
