Direct replacement battery

This Cameron Sino Li-Polymer cell is built for Sony Walkman models NW-E435, NW-E435F, NWZ-E436, NWZ-E436F, NWZ-E436FBLK, NWZ-E436FBLU, NWZ-E436FPNK, NWZ-E438FBLK, NWZ-E438FPNK, NWZ-E438FRED and SOK-NWZ-E435F(B). It matches the original 1-756-819-11 part and delivers 3.7V 570mAh in a black 51.40 x 34.54 x 3.56 mm pack.

Upgrade from a worn original

When the factory cell no longer holds a charge through a full playlist, this 100% OEM-compatible unit restores the rated runtime without modifying the player. The swap is worth it once the original battery drains noticeably faster than when new or shows any swelling.

Fits the existing compartment

The slim 3.56 mm profile slides into the Walkman’s battery bay with no case alterations or extra wiring. No soldering is required; the connector aligns with the board layout used on the listed models. Buyers needing a higher-capacity pack or a different voltage should look elsewhere.

Questions about this item

Will the 51.40 x 34.54 x 3.56 mm battery fit my NWZ-E436?

Yes, the dimensions match the original 1-756-819-11 cell used in the NWZ-E436, NWZ-E436F, NWZ-E436FBLK and NWZ-E436FBLU models.

How do I install the DS-CS-SAE430SL without damaging the flex cable?

Open the Walkman case, disconnect the old pack by lifting the connector latch — not by pulling the wires — then press the new battery connector straight in until it clicks.

When should I replace the 3.7 V 570 mAh pack?

Replace it when a full charge no longer lasts through a typical listening session or the device shuts down unexpectedly despite showing remaining charge.
