Intermec CV61 Replacement Battery 7.4V 2600mAh Li-ion

Intermec CV61 / CV61A — 7.4V Li-ion Replacement Battery (VE027-8018-A0)

This 7.4V, 2600mAh Li-ion battery replaces the original pack in the Intermec CV61 and CV61A mobile computers, as well as the 1011CM01 variant. These rugged handheld units run warehouse and field data-collection workflows, and a degraded cell will cause the device to cut out mid-task. Voltage and capacity match OEM spec exactly.

• CV61, CV61A, and 1011CM01 fit: All three share the same 7.4V battery bay, connector pinout, and BMS handshake protocol. One pack covers the full CV61 platform without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a CV61 unit. The BMS accepted the pack on first insertion, reported state-of-charge correctly after a calibration cycle, and held voltage within spec under sustained Wi-Fi and scanning load.
• Fuel gauge recalibration after swap: After installing this battery, run the CV61 down to automatic shutoff — do not force it off — then charge uninterrupted to 100%. This single full cycle resets the fuel gauge IC calibration against the new cell and clears the inaccurate percentage reading that almost always appears after a pack swap.

CV61 shutting down at 15–25% remaining after battery swap

The CV61's fuel gauge IC was calibrated to the original cell's discharge curve. A new cell with a slightly different curve causes the IC to miscalculate the remaining capacity cliff. When the display backlight, Wi-Fi radio, and barcode scanner run simultaneously, current draw spikes and the battery management system trips the cutoff before the gauge reaches zero. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100%. That single cycle re-anchors the gauge to the new cell's actual voltage curve and stops the premature shutdowns.

CV61 percentage dropping faster than expected from 100%

This is gauge drift — the IC is still mapping charge levels against the old cell's capacity profile. The new 2600mAh cell holds more energy than the gauge expects at each voltage step, so it counts down faster near the top of the range. The fix is the same calibration cycle: discharge fully to automatic shutoff, then charge uninterrupted to 100% without interruption. After that cycle, the percentage display stabilises and tracks actual remaining capacity correctly from 100% down.
