Citizen CMP-BA30II CMP30II Lion Battery

Overview

The CMP-BA30II is a 2600mAh lithium-ion replacement battery designed for Citizen CMP-30 series mobile thermal printers (Type I and Type II variants). This battery restores full runtime capacity when the original battery has degraded — a critical swap for field teams running extended shifts without access to frequent charging infrastructure. The 2600mAh capacity supports 8–12 hours of typical printing operations depending on label volume and environmental conditions.

Compatibility

The CMP-BA30II works exclusively with Citizen CMP-30 Type I and Type II mobile printers. Verify your device model before ordering — this battery is not cross-compatible with other Citizen thermal printer lines or non-Citizen equipment.

Installation Notes

Battery replacement requires opening the device's battery door (typically secured by a latch or small screw). Insert the CMP-BA30II observing polarity markings inside the compartment — incorrect orientation prevents power delivery. Allow the printer to fully charge on a standard Citizen charger before first use; lithium-ion cells perform best after an initial full cycle. Avoid exposure to temperatures above 50°C (122°F) or below 0°C (32°F) during storage or operation — cold environments significantly reduce available capacity and may trigger low-battery warnings prematurely.
