The B27 lithium-ion battery powers the CR2700 readers with a unique set of features that keep workflow interruptions to a minimum. It has enough power to last up to 50,000 scans per charge. It has a built-in power gauge that shows battery power status intuitively every time the reader is triggered to scan or the power gauge button is pressed. When the battery is running low, a quick-release latch allows easy swapping for a fully charged battery without the need to use any tools. To proactively manage the life-cycle of the battery, the B27 accepts a custom date code to track deployment date. In addition, battery health information is available to device or asset managers to track residual battery capacity.
