About this replacement
Getac PS535E Series — 3.7V Li-ion Replacement Battery (441816800010)
This is a 3.7V, 2400mAh Li-ion battery for the Getac PS535E handheld barcode scanner and related models including the PS535, PS535F, and FC-25A. It replaces OEM part number 441816800010 and fits the same battery bay without modification. Voltage and capacity match factory spec directly from Getac's product line.
- PS535 platform compatibility: The PS535, PS535E, PS535F, and FC-25A all share the same 3.7V cell format and BMS handshake protocol. One battery fits the full platform because Getac kept the same connector pinout and communication bus across these variants.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a PS535E unit. The BMS accepted the pack without fault codes, charge termination triggered correctly at full capacity, and the scan trigger drew current normally throughout the test.
- First-shift cradle protocol: After installing this pack, place the scanner in its cradle for a complete charge cycle before starting pick-and-pack operations. Scan trigger inrush is highest when the cell is near minimum charge — starting a shift on a partially charged new cell can trip the BMS on the first heavy scan burst.

Charging docks on the PS535 platform read battery state through pogo pin contacts on the base of the scanner. If those contacts have oxidation or debris from warehouse use, the dock may report a fault rather than begin charging. Wipe the contacts on both the battery and the dock with a dry cloth, reseat the scanner firmly, and check that the charge LED changes state within 30 seconds. If the error clears, the cell was never the problem — contact resistance at the dock was.
Scanner losing wireless connection during rapid scan bursts
The PS535E runs its wireless radio and scan imager simultaneously during active picking. Under rapid scan conditions, the combined current draw from both the radio transmit cycle and the imager trigger can cause a momentary voltage sag on a low or degraded cell. The BMS interprets this sag as an under-voltage event and briefly cuts output, which drops the wireless session. Charge the battery to full before each shift and confirm the cell rests above 3.6V under no-load before docking the scanner into a live RF environment.
