About this replacement
SCANGRIP I-View COB LE — 3.7V Li-Polymer Replacement Battery (03.5328)
This 3.7V, 1400mAh Li-Polymer battery replaces the internal rechargeable cell in the SCANGRIP I-View COB LE work light (03.5026) and the I-Match (03.5412). It matches the original 55.50 × 25.40 × 9.00mm cell footprint, OEM part number 03.5328. Swap it in when the original cell no longer holds a usable charge through an inspection job.
- I-View and I-Match platform fit: These SCANGRIP inspection lights share the same slim-profile Li-Polymer cell format, connector pinout, and driver board interface — one part number covers the full range listed above.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the I-View COB LE driver board. The BMS accepted the cell without error, current draw matched OEM levels, and the driver stepped through all output modes correctly.
- Single-cell replacement protocol: The I-View COB LE runs one Li-Polymer cell — not a multi-cell pack. Before reinstalling, confirm the replacement cell rests at 3.6–3.7V open-circuit. Installing a deeply discharged cell below 2.5V can cause the driver to reject it on first charge.
Flashlight dimming before the battery indicator reads low
The I-View COB LE driver uses brownout protection to step output down before the cell reaches its cutoff threshold. This is not a battery fault — it is the driver protecting the cell from hard discharge. What you see as early dimming is the driver reducing current draw as cell voltage sags under load. On an aged cell, internal resistance rises, so voltage sag happens earlier in the discharge curve than it did when the cell was new. A fresh 1400mAh cell at full charge restores the full-output window before the driver steps down.
Flashlight not charging after the cell fully depleted
Li-Polymer cells that discharge below 2.5V trigger a low-voltage lockout in most charger circuits, including the one built into the I-View COB LE. The charger sees the cell as a fault condition rather than a flat battery and refuses to begin the charge cycle. If the indicator shows no activity at all when plugged in, the cell has likely dropped below recovery threshold. Replace the cell — at this point, the original cell will not recover reliably even if a trickle-charge workaround brings it back above 3.0V.
