CMOS Battery for Symbol MC1000

This nickel-metal hydride CMOS battery is built for the Symbol MC1000 handheld computer and its listed part-number variants. It supplies the low-voltage backup power that keeps the real-time clock and BIOS settings alive when the main pack is removed or depleted. The cell is brand new and manufactured to match the original equipment specifications. It is not intended for devices outside the MC1000 family or for primary power applications.

Ni-MH chemistry and voltage

The cell uses Ni-MH chemistry rated at 3.6V and 20mAh, delivering 0.07Wh of energy capacity. In normal standby operation the current draw is in the microampere range, so the battery can maintain CMOS data for extended periods without measurable self-heating. No active cooling or thermal management is required and the component operates silently within the sealed chassis. Power consumption is negligible compared with the main system battery.

Sustained data retention

Under continuous standby load the battery maintains the CMOS supply voltage without interruption until its stored charge is exhausted. There is no high-current burst behaviour to consider; the load profile is flat and the voltage curve follows standard Ni-MH discharge characteristics. Replacement intervals depend on how long the handheld spends without its main battery installed. The part is a direct swap for the original CS-MC1000BU cell.

Questions about this item

How do I install the CMOS battery in my Symbol MC1000 and which step do people often miss?

Open the device, unplug the old two-wire connector, insert the new 43.45 x 12.68 x 4.63 mm pack, and reconnect; the step most often missed is seating the connector fully so the 3.6 V supply reaches the real-time clock.

What maintenance or replacement will this Ni-MH 20 mAh cell need later?

The 0.07 Wh Ni-MH cell typically holds the CMOS settings for several years; when the clock starts drifting, simply replace the battery — no charging circuit or calibration is required.

What is the first limit that appears under sustained use of this 0.02 Ah CMOS battery?

The 20 mAh capacity is the limiting factor; once the stored charge drops below what the real-time clock needs, the system loses date and time settings until the cell is swapped.
