Replacement battery for HP TPN-W129 series

This 41.6Wh lithium-polymer battery operates at 14.6V and delivers 2850mAh capacity. It replaces original part numbers including JC03, JC04, 919700-850, 919701-850 and several HSTNN codes. Designed for HP laptops such as the 240 G6, 245 G6, 250 G6 and multiple 14, 15 and 17-inch series.

Thermals noise and power in normal use

Lithium-polymer chemistry runs cool during typical charge and discharge cycles with no moving parts to generate noise. The 14.6V output matches the original specification so the laptop power management sees no difference. Normal use produces negligible heat and silent operation.

Supplied connectors match original layout

The pack ships with the same connector arrangement as the factory battery so installation requires no adapters or cable modifications. No software, drivers or calibration utilities are bundled because the laptop firmware handles recognition automatically. The physical dimensions align with the original battery bay for a direct fit.

Questions about this item

How do I install the JC04 battery in my HP 240 G6, and which step do people often miss?

Power off the laptop, unplug the AC adapter, remove the bottom case screws, disconnect the old battery cable before lifting it out, connect the new JC04 cable firmly, then reassemble — the step most people skip is disconnecting the old battery cable first.

What maintenance or replacement will the JC04 Li-polymer 41.6Wh pack need over time?

The JC04 uses Li-polymer cells at 14.6V and 2850mAh; capacity fades with each charge cycle, so replace the pack when run-time no longer meets your needs.

What limit appears first during sustained use of the JC04 in an HP 15-bw series laptop?

The 41.6Wh capacity sets the runtime ceiling; under continuous load the pack will hit its discharge limit before any thermal throttle occurs.
