Compatible replacement battery

This lithium-ion cell is a direct replacement for the Sony NW-A1000, NW-A1200, NW-A1200s and NW-A1200v Walkman players. It matches the original 1-157-607-11 and CT019 part numbers. The pack supplies 3.7V and 450mAh for 1.67Wh of energy. Buyers with other Sony models or different battery codes cannot use this item.

Physical fit and electrical match

The cell measures 38.90 x 23.60 x 6.50 mm and slides into the Walkman battery compartment without modification. Its black casing aligns with the original design. The 100% OEM-compatible specification means the connector and voltage rails line up with the player’s power management circuit. No soldering or adapter cables are required for installation.

Steady discharge under load

Lithium-ion chemistry delivers a stable 3.7V output throughout most of the discharge cycle rather than a sharp voltage drop. The 450mAh capacity supports extended playback sessions at consistent volume levels. Self-discharge remains low when the player sits idle between uses. The cell is not suited for devices that demand higher current draw or larger capacity packs.

Questions about this item

How long will the 450 mAh cell run before voltage drops under continuous playback?

The 3.7 V lithium-ion pack stores 1.67 Wh, so runtime depends on the player's current draw; at 50 mA it would last roughly nine hours.

Does the battery get hot or make noise during all-day use in a Walkman?

Lithium-ion cells produce no audible noise and only mild warmth under normal load; excessive heat suggests a fault in the player's charging circuit.

Which original Sony part numbers must match for this replacement to fit?

The cell replaces Sony part numbers 1-157-607-11 and CT019, used in NW-A1000, NW-A1200, NW-A1200s and NW-A1200v models.
