Cameron & Co CMOS Battery 3.0V 550mAh 1.65Wh Green

SKU CH-PB79-64A6R

A 3.0 V lithium CMOS battery delivering 550 mAh for VeriFone 802B and NURIT 8020 terminals

  • TypeBattery
  • Compatible with VeriFone 802B and NURIT 8020 devices
  • 0V 550mAh capacity delivers 1.65Wh of backup power
  • Lithium chemistry provides reliable CMOS memory retention
  • Compact 24.80 x 24.60 x 6.10 mm form factor fits tight spaces
  • Green housing matches original equipment appearance

VeriFone CMOS replacement battery

This 3.0V lithium cell is a direct replacement for the CMOS backup battery in VeriFone 802B-WW-M05 and NURIT 8020 payment terminals. It restores the real-time clock and preserves configuration data when main power is removed. Technicians servicing point-of-sale hardware will find it matches the original CS-VFT802BU part number. The green housing identifies the Cameron Sino DS-CS-VFT802BU model at a glance.

Passive thermal profile and negligible draw

As a non-rechargeable lithium CMOS cell it generates no measurable heat during normal operation. Current draw is in the microampere range so the 550mAh capacity supports years of continuous backup without replacement. Silent solid-state chemistry means no fan noise or coil whine can occur. The terminal simply retains its settings through power cycles and overnight shutdowns.

Compact green package with wire leads

The battery measures 24.80 by 24.60 by 6.10 millimetres and fits the original compartment without modification. Pre-attached leads connect directly to the terminal’s CMOS header eliminating solder work. Green colour coding helps distinguish this 1.65Wh cell from other coin or pack batteries in a service kit. Build quality meets OEM specifications for reliable long-term contact retention.

Questions about this item

How do I install the 24.80 x 24.60 x 6.10 mm CMOS battery and what step is often missed?

Slide the battery into its holder with the green side facing up until it clicks; the step often missed is confirming the 3.0V polarity matches the board markings before powering on.

What replacement will this 550mAh lithium cell need later?

As a non-rechargeable lithium CMOS battery, the cell itself is the only replaceable part; swap it for another 3.0V 1.65Wh unit when the system clock starts drifting.

At what point does the 0.55 Ah capacity limit appear under continuous backup load?

The 1.65Wh rating supports typical CMOS draw for years; the limit shows up first as voltage sag below 3.0V when the 550mAh reserve is exhausted.
