Gateway GWTN156 replacement battery

This 11.4V 57Wh lithium-polymer pack replaces part numbers U478388PV-3S1P, U478388PV, 478388PV-3S1P and 3ICP5/83/88 in Gateway GWTN156-12BL, GWTN156-12BK, GWTN156-12GR and GWTN156-12RD series notebooks. It is a new unit built with quality cells and an integrated smart chip for stable current delivery. Buyers with other laptop models or different voltage requirements cannot use this pack.

Build quality and daily fit

The battery uses high-grade materials and top-tier circuit boards tested for correct voltage, circuit protection and low self-discharge. CE, FCC and RoHS certifications confirm compliance with safety and environmental standards. The 3S1P cell arrangement matches the original mechanical layout so the pack seats securely in the existing bay without adapters. Users who need a higher cycle-life chemistry or a different form factor will not be served by this design.

57Wh capacity decides suitability

At 5000mAh and 57Wh the pack delivers roughly the same runtime as the factory battery and is rated for about 500 recharge cycles over its service life. This capacity figure is the primary metric for deciding whether the unit meets a specific workload. Customers who require significantly longer unplugged time per charge should look elsewhere.

Questions about this item

What voltage does the 11.4V 57Wh Li-Polymer battery deliver to the Gateway GWTN156 series?

The battery supplies 11.4 volts at 57 watt-hours and 5000 milliampere-hours, matching the original U478388PV-3S1P specification for the Gateway GWTN156-12BL, GWTN156-12BK, GWTN156-12RD and GWTN156-12GR notebooks.

Which part numbers does the 3ICP5/83/88 cell pack replace in the Gateway GWTN156 chassis?

It replaces U478388PV-3S1P, U478388PV and 478388PV-3S1P, fitting the same battery bay used in the Gateway GWTN156-12 series without modification.

How is the replacement battery installed in the Gateway GWTN156, and what step is often missed?

Power off the notebook, remove the bottom case screws, disconnect the old pack connector, fit the new 3ICP5/83/88 unit, reconnect the cable firmly, then replace the case screws; the step most often missed is fully seating the connector before reassembly.
