Warning Misuse or improper installation of the internal lithium battery
can cause severe injury. Fire, explosion, and severe burns can result. Do
not recharge, disassemble, heat above 100 °C (212 °F), solder directly to
the cell, incinerate, or expose contents to water. Dispose of spent lithium
batteries properly.
A lithium battery backs up the CR800 clock, program, and memory.

If the CR800 datalogger sits near a PC, direct-connect serial communication is
usually the best solution. In the field, direct serial, a data storage device, can be
used during a site visit. A remote comms option (or a combination of comms
options) allows you to collect data from your CR800 over long distances. It also
allows you to discover system problems early.
A Campbell Scientific sales engineer can help you make a shopping list for any of
these comms options:
• Standard
o RS-232 serial
• Options
o Ethernet
o Mass Storage
o Cellular, Telephone
o iOS, Android
