Replacement Battery for Sony Walkman Players

This lithium-polymer cell replaces the original power pack in compatible Sony Walkman models including the NW-A805, NW-A806, NW-A808, NW-A815, NW-A816 and NW-S639 series. It matches the OEM part numbers 1-756-702-11, 7607A12353 and LIS1374HNPA for direct fitment. The 3.7V 650mAh capacity restores the player’s original runtime between charges.

Sustained Playback Performance

The 2.41 Wh energy rating delivers consistent output during continuous audio playback rather than only brief peak bursts. Li-Polymer chemistry maintains stable voltage across the discharge curve so the player does not shut down early under steady load. The slim 3.65 mm profile fits the original compartment without forcing the case or stressing the connector.

3.7V 650mAh Capacity Decides Fit

This single rating determines whether the cell is the correct replacement; a different voltage or milliampere-hour value would not work in the listed Walkman models. Buyers needing a higher-capacity pack for extended travel or a different connector layout for another device cannot use this battery.

Questions about this item

Does the 3.7 V Li-Polymer cell run hot or draw extra power during all-day playback?

The 650 mAh pack is designed to match the original 2.41 Wh specification, so heat and current draw stay within the Walkman's normal operating range.

What must I already own for this battery to work?

You need one of the listed Sony Walkman models such as the NW-A805, NWZ-A810 or NW-S639, plus a small screwdriver to open the case.

Will it fit and function in an older NW-A805 that I still use?

Yes, the 51.56 x 34.58 x 3.65 mm dimensions and 1-756-702-11 part number match the original cell used in the NW-A805 and NWZ-A810.
