Snow Video Magnifier R001710000 Compatible Battery 3.7V 1700mAh

Snow Video Magnifier — 3.7V Li-ion Replacement Battery (R001710000)

This is a 3.7V, 1700mAh Li-ion battery for the Snow Video Magnifier portable low-vision device. It replaces OEM part R001710000. When the original cell degrades and the unit no longer holds charge away from the mains, this battery restores full portability.

• Snow Video Magnifier fitment: The R001710000 cell sits inside a compact PCB housing — 66.20 × 44.00 × 5.10mm. The BMS negotiates with the device's charge controller over the same voltage rail the original used. No modifications needed for the connection.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Video Magnifier platform. The BMS held the cutoff correctly at the low-voltage threshold, and the charge controller accepted the cell without fault codes.
• First-charge protocol for this device: The Snow Video Magnifier's charge indicator can misread state-of-charge on a fresh cell. Run a full charge cycle from flat before relying on the battery indicator — the device calibrates its gauge on the first complete cycle.

Why the Video Magnifier shuts off suddenly during use

The display backlight and camera module draw current together during active magnification. On an aged or partially charged cell, this combined draw can pull the cell voltage below the BMS cutoff threshold, triggering a sudden shutdown. This is not a device fault — it is the BMS protecting the cell from deep discharge. Charge fully and the shutdowns will stop; if they continue on a full charge, the original cell's capacity has degraded past recovery.

This is a gauge calibration drift — common when a cell is replaced or has been stored partially charged. The device's fuel gauge retains the old cell's charge curve and misreports remaining capacity. Run the new cell down to the auto-off point, then charge uninterrupted to 100%. After one full cycle, the indicator will track the new cell's actual capacity correctly.
