Replacement Battery for Razer Edge Pro Controller

This GreenTech RC81-0112 battery is a compatible replacement for the Razer Edge Pro Controller Tablet. It matches the original specifications with a four-cell lithium-ion design rated at 14.8V and 2800mAh. The unit is intended for owners who need to restore runtime to a device with a degraded or failed original pack.

Tested Cells and Safety Certifications

Each battery undergoes pre-shipment testing for correct voltage, circuit protection, stable current delivery and low self-discharge. The pack carries CE, FCC and RoHS certifications for safety compliance. As a lithium-ion unit, it produces no fan noise and draws no power while the host device is off or asleep.

Direct OEM Part Substitute

This unit replaces OEM part numbers RC81-0112, AHA44128036 and RC81-01120100. The upgrade is worthwhile when the original battery no longer holds sufficient charge for portable use or when the tablet shuts down unexpectedly under load. It is not a higher-capacity alternative and will not extend runtime beyond the factory specification.

Questions about this item

How do I install the RC81-0112 battery in the Razer Edge Pro controller tablet and what step is often missed?

Power off the tablet, remove the back cover screws, disconnect the old battery cable, connect the new 14.8 V pack, then reassemble; the step often missed is fully seating the connector before screwing the cover back on.

What maintenance will the 4-cell lithium-ion pack need over its life?

No scheduled maintenance is required; avoid storing it fully discharged and keep it between 20 % and 80 % charge when unused for weeks.

What limit appears first during sustained heavy use of the 2800 mAh battery?

Thermal throttling — the tablet reduces performance once the pack temperature reaches its internal safety limit.
