Replacement battery for HP 7.7V systems

This 47.3Wh lithium-ion pack replaces HP part numbers HSTNN-UB7M, HSTNN-DB7X, HSTNN-IB8W, L42583-002, L42550-2C1 and L42583-005. It is built for owners of compatible HP laptops who need a new power source after the original cell has degraded.

Practical limits of a 7.7V 2-cell pack

The 7.7V nominal voltage and 47.3Wh capacity are fixed by the two-cell design, so runtime will match the original specification rather than exceed it. The battery only fits machines that accept those exact HP part numbers; it will not work in systems requiring a different voltage or cell count.

Build quality and daily implications

CE and RoHS markings confirm compliance with safety and environmental standards. A one-year replacement warranty covers defects in materials or workmanship. The pack is engineered to slot into the existing battery bay without modification, letting you swap the old unit and resume normal use.
