About this replacement
Intermec CV61 / CV61A — 7.4V Li-ion Replacement Battery (VE027-8018-A0)
This 7.4V 3350mAh Li-ion battery replaces the original pack in the Intermec CV61 and CV61A rugged mobile computers, as well as the 1011CM01 variant. It matches the OEM voltage rail and connector footprint. Fits units used in warehouse scanning, inventory, and field data capture workflows.
- CV61 and CV61A platform fit: Both the CV61 and CV61A share the same battery bay, voltage rail, and BMS handshake protocol. The 1011CM01 variant uses the same pack — one SKU covers all three.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the CV61 platform. The BMS negotiated correctly with the device charge IC — no fault flags, no charge interruption, voltage held steady across the cycle.
- Fuel gauge reset after installation: After fitting this battery, run the CV61 down to automatic shutoff, then charge uninterrupted to 100%. The CV61's fuel gauge IC is calibrated against the old cell — this single full cycle resets it against the new pack and resolves inaccurate percentage readings from the first boot.
CV61 shutting down at 20% remaining after battery replacement
The CV61 uses a fuel gauge IC that tracks charge state by measuring voltage curves from the previous cell. A new cell has a different voltage-to-capacity curve, so the IC misreads remaining charge and triggers a low-battery shutdown earlier than it should. This happens consistently on first use with a replacement pack. One full discharge-to-shutoff followed by a full uninterrupted charge resets the IC. After that cycle, the CV61 should hold charge to within a few percent of actual capacity before cutting out.
CV61 showing wrong battery percentage after swap
Swapping the battery pack doesn't reset the fuel gauge automatically — the CV61 wakes up and maps the new cell against stored calibration data from the old one. This produces readings that jump, stall, or drop faster than expected, especially between 80% and 40%. The fix is one complete recalibration cycle: discharge fully until the device shuts itself off, then charge to 100% without interruption. The percentage display stabilises after that cycle completes.
