Battery pack HP 812148-855BU — Primary 4-cell Lithium‑ion battery for portable devices

HP 812148-855BU is a primary 4-cell lithium‑ion battery pack designed to deliver stable single‑use power for compatible portable devices. As a non-rechargeable battery, it is intended for applications where a dependable, long shelf‑life energy source is required and where the original HP part specification is called for. The pack is constructed to integrate into devices that accept the specified form factor and electrical characteristics, providing predictable voltage and discharge behavior for reliable operation in the field.

Advantages

The 4-cell configuration offers consistent voltage output and prolonged service life during a single usage cycle compared with smaller single‑cell alternatives. Being a primary lithium‑ion unit, it features low self‑discharge for extended storage, stable performance across a range of temperatures, and compatibility with equipment designed for this HP part. The sealed construction reduces maintenance needs and minimizes the risk of leakage or contamination.

Suitable for

• Replacement of OEM primary battery packs in compatible portable equipment
• Backup power for devices requiring long-term shelf readiness
• Integration into devices or systems specifying a 4-cell primary lithium‑ion pack
• Maintenance operations where a non-rechargeable, stable power source is required

Key specifications

• Chemistry: Primary (non‑rechargeable) lithium‑ion
• Cell count: 4 cells
• Form factor: Pack designed for compatible portable devices
• Intended use: Single‑use / long‑term backup power
• Construction: Sealed pack for reduced maintenance
• Storage characteristics: Low self‑discharge for extended shelf life

How to use

Install the battery pack only into devices that explicitly specify compatibility with this type of primary 4‑cell lithium‑ion pack and the corresponding mechanical and electrical interface. Ensure the device is powered off before inserting the pack and follow any manufacturer instructions for securing the battery in place. Do not attempt to recharge the pack, and avoid exposing it to extreme heat, open flame, or prolonged direct sunlight. After the battery has reached end of service, dispose of it according to local regulations for primary lithium batteries.

Usage recommendations

Store the pack in a cool, dry place and keep it away from conductive materials and metal objects. For best long‑term reliability, avoid prolonged storage above recommended temperature ranges and inspect device contacts for corrosion before installation.
