SKU CH-ET5A-V4WAW

Ni-MH CMOS battery keeps real-time clock settings on Symbol MC30, MC3000 and MC3090 handhelds

  • TypeBattery
  • Reliable system clock on Symbol MC30 MC3000 MC3090 devices
  • Ni-MH chemistry delivers steady backup power for CMOS settings
  • 02 Ah capacity suits low-drain real-time clock circuits
  • Green housing aids quick identification during field service
  • Direct replacement fits MC3000R MC3070 MC3090G variants without modification

Compatible CMOS Battery for Symbol MC30 Series

This Cameron Sino replacement battery suits Symbol MC30, MC3000, MC3070 and MC3090 handheld computers. It uses Ni-MH chemistry with a 0.02 Ah capacity to maintain system settings when main power is removed. The green cell matches the original form factor for direct installation.

Build Quality and Connector Design

The unit ships new from Cameron & Co as a direct drop-in part for the listed Symbol models. Its pre-wired connector mates with the motherboard header without soldering or adapter cables. The compact housing fits the original battery compartment exactly, so no case modification is required during replacement.

Practical Limits of Ni-MH CMOS Cells

Ni-MH chemistry self-discharges faster than lithium alternatives, so the battery will lose charge if the device sits unused for extended periods. Capacity of 0.02 Ah is sized only for real-time clock and CMOS retention, not for powering the handheld during operation. Users needing longer shelf life between uses should plan for periodic recharging or replacement.

Questions about this item

What connector standard does the DS-CS-MC3000BU use to fit the MC3000 and MC3090 series?

The DS-CS-MC3000BU uses the original equipment connector specified for Symbol MC30, MC3000 and MC3090 models, ensuring a direct plug-in without adapters.

What physical clearance does the green Ni-MH cell require inside the MC3000 or MC3090 chassis?

The green Ni-MH cell matches the factory CMOS battery dimensions for MC3000 and MC3090 units, fitting the existing holder without modification.

How is the DS-CS-MC3000BU installed, and which step do installers often miss?

Remove the old cell, plug the new DS-CS-MC3000BU into the same header, then reseat the main battery so the MC3000 or MC3090 recognises the fresh CMOS power.
