Direct replacement for select HP laptops

The eReplacements TPNC104ER is a new four-cell laptop battery built to match the original specifications for compatible HP models. It restores mobile power for users whose factory pack no longer holds a useful charge.

Upgrade from a depleted or failing original pack

When the original battery drains quickly, fails to charge fully or triggers a replacement warning, this unit returns the notebook to its intended runtime. The jump is worth it whenever the existing pack can no longer sustain a typical work session away from mains power.

Limited to the HP models listed by the manufacturer

Compatibility is defined solely by the manufacturer part number TPNC104ER and the associated HP model list. Systems outside that list will not recognise or charge the pack correctly, so buyers must verify the exact model match before purchase.

Questions about this item

What HP laptop models does the TPNC104ER battery fit?

The TPNC104ER is a 4-cell replacement battery built for select HP laptop models; check your device's service manual or original battery part number to confirm exact fit before ordering.

How do I install the TPNC104ER battery, and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the old pack, insert the TPNC104ER until the latches click, then reconnect the AC adapter and let it charge fully before first use — skipping the initial full charge is the common mistake.

When will the TPNC104ER battery need replacement?

Capacity declines with every charge cycle; when run-time no longer meets your needs, replace the pack — the TPNC104ER has been listed by the manufacturer since 2026, so genuine spares should remain available.
