The Motorola BTRY-LS34IAB00-00 spare battery is a 2,200 mAh lithium-ion battery that can be used to power a Motorola DS3478, DS3578, LS3478, or LS3578 barcode reader for scanning barcodes. The battery can be charged in approximately 3 hours.

Barcode scanners, also known as barcode readers, can be used to scan and decode barcodes and to transmit barcode data to a computer or another host system. Barcode readers with a single-line laser can be used to scan linear, one-dimensional (1D) barcodes. Some lasers can produce light in an omnidirectional pattern to allow scanning of barcodes from different angles. Other barcode readers contain CCD (charge-coupled device) light sensors instead of a laser for accuracy and wear resistance. Barcode scanners with raster scanning, area imaging, and other scanning technologies can allow scanning of two-dimensional (2D) or Portable Document Format 417 (PDF417) barcodes, among other types. Some barcode readers provide onboard flash memory to allow the storage of barcode data before transmitting it to a computer or host system through a USB cable or wireless WLAN or Bluetooth connection. Many barcode readers have a handle for handheld use and come with a stand or a charging cradle for fixed position applications, while others are designed for stationary use on a counter or another flat surface. Some portable readers are small enough to be carried in a pocket or attached to a lanyard. Barcode readers are used at retail checkout counters and other points of sale (POS) locations and in warehouses and shipping facilities.

Motorola Solutions manufacturers mobile computing devices, radios, tables, and data capture devices such as barcode scanners and RFID products. The company, founded in 1928, is headquartered in Schaumburg, IL.
