Replacement battery for Steam Deck

This new lithium-ion battery delivers 7.7 V and 40.04 Wh of capacity. It is a direct replacement for the original F7A pack used in the Steam Deck gaming handheld PC. The black unit ships as a single battery ready for installation.

Capacity match decides fit

The 40.04 Wh rating must match the original battery specification printed on your device. Verify that the part number 2(ICP6/48/36+ICP6/57/80)-2 appears on your existing pack before ordering. A different watt-hour value indicates a different internal cell configuration that will not fit.

Internal swap needs care

Installation requires opening the handheld chassis and disconnecting the original battery connector. The replacement uses the same connector layout, but ribbon cables and screws are fragile. Common issues include stripped screw heads, torn flex cables and forgetting to reconnect the battery before reassembly.

Questions about this item

How long will the 40.04 Wh capacity last in a Steam Deck?

The 40.04 Wh rating matches the original battery, so real-world runtime in a Steam Deck will be the same as when the device was new, varying only with screen brightness and game load.

Does the 7.7 V rating work with the Steam Deck charging circuit?

Yes, 7.7 V is the factory voltage for the Steam Deck, so the handheld charges and reports capacity normally without any firmware change.

Will the F7A 2(ICP6/48/36+ICP6/57/80)-2 pack fit inside the Steam Deck case?

The part number matches the OEM cell layout, so the pack uses the original dimensions and screw points and drops straight into the Steam Deck chassis.
