SanDisk Sansa View 8GB Replacement Battery 3.7V 600mAh

SanDisk Sansa View Series — 3.7V Li-Polymer Replacement Battery (805193192)

This 3.7V, 600mAh Li-Polymer cell replaces the original battery in the SanDisk Sansa View portable media player. It fits the Sansa View 8GB, 16GB, and 32GB models, including the SMDX10R-8192K-P70 variant. Install it when the original cell no longer holds a charge or the player fails to power on.

• Sansa View series fit: All Sansa View capacities share the same battery bay dimensions, connector pinout, and 3.7V nominal rail. The cell footprint is 42.87 × 41.15 × 3.10mm — a match across the full range without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a Sansa View unit. The BMS accepted charge current normally, voltage held steady through audio and video playback, and the protection circuit tripped correctly at the low-voltage threshold.
• First-charge after storage: If the player sat unused for months before this swap, connect it to the charger before pressing the power button. Extended storage can push the cell into deep-discharge protection, and the device needs slow trickle current before it will accept a normal charge rate or respond to input.

Battery percentage jumping after a cell swap on the Sansa View

The Sansa View reads battery level by measuring cell voltage against fixed thresholds stored in firmware. A new cell has a slightly different discharge curve than the aged original, so the percentage display can jump — showing 80% one moment, then dropping to 50% minutes later. This is not a fault with the replacement cell. Run two or three full charge-to-discharge cycles and the firmware's voltage-to-percentage mapping will settle against the new cell's actual curve. After that, the indicator stabilises.

Playback cutting out before the battery indicator reads empty

Near the end of discharge, cell voltage sags under the load of the audio amplifier circuit. If the sag pulls voltage below the BMS cutoff — even briefly — the player shuts down while the indicator still shows charge remaining. This happens most often with video playback, which draws more current than audio alone. Check the cell voltage with a multimeter after a cutout: if it reads above 3.0V at rest, the BMS tripped on load sag rather than true depletion. A fresh charge cycle resolves it; if the behaviour repeats consistently, the USB cable or port may be limiting charge current and the cell is not reaching a full 4.2V at end of charge.
