Intermec AB12 IP3 Barcode Scanner Replacement Battery 3.7V

Intermec IP3 / IP4 — 3.7V Li-ion Replacement Battery (AB12 / 318-014-001)

This 3.7V, 3400mAh Li-ion battery replaces the AB12 and 318-014-001 packs in the Intermec IP3 and IP4 handheld barcode scanners. These are mobile data capture devices used in retail, warehouse, and logistics environments. Dimensions are 96.20 × 29.50 × 25.00mm — check your existing pack before ordering if you are unsure which model you have.

• IP3 and IP4 platform fit: Both scanners run the same 3.7V single-cell architecture and use the same dock connector pinout, so one battery pack services either unit without wiring or firmware changes.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless polling loads. The BMS held voltage above the 3.2V low-cell threshold throughout, and charging terminated cleanly at 4.2V with no dock error codes.
• First-shift preparation: After installing, seat the scanner in its charging cradle and run a full charge cycle before pulling it into a pick-and-pack shift. The scan trigger draws the highest inrush current when the cell is near minimum, and a fully charged pack prevents the BMS from tripping on that first heavy burst.

Cradle showing a charging error on a new pack

A charging error on a freshly installed battery almost always comes down to contact resistance at the dock interface, not a fault with the cell itself. Dust, oxidation, or a small film of hand oil on the pack's gold contacts is enough to prevent the cradle from reading the pack's thermistor line correctly. Wipe the contacts on both the pack and the cradle with a dry lint-free cloth, then reseat the scanner firmly until you hear the latch click. The charge indicator should switch to amber within a few seconds; if it does not, check cradle contact spring tension before assuming the pack is at fault.

Scanner losing wireless connection during a rapid scan burst

The IP3 and IP4 draw current simultaneously from the imager and the wireless radio during a fast scan run. If the cell voltage sags below roughly 3.4V under that combined load, the radio drops its connection while the imager keeps firing — so the scanner still reads barcodes but stops transmitting. This is not a firmware or network issue; it is a cell-voltage-under-load problem. A fresh, fully charged pack resolves the sag, because the internal resistance of a degraded cell is what causes the voltage to collapse under dual-draw conditions.
