Overview
The BPALK is a battery pack for powering dataloggers and peripherals. The BPALK includes eight replaceable D cell alkaline batteries. To ensure power is not lost while the D cell batteries are replaced, the BPALK has a 12 V backup battery pack that uses eight AA batteries (not included).

Technical Description
The BPALK can power a CR500, CR510, CR10, CR10X, CR800, CR850, or CR1000 datalogger, as well as the datalogger's peripherals. It consists of the alkaline batteries, battery connectors, and the temporary 12 V AA alkaline battery pack used during D cell replacement.
The BPALK can also be used as a separate auxiliary 12 V power supply to power remotely located sensors or peripherals. The system must have a common ground.
Alkaline batteries are not rechargeable, and their Amp hour ratings decrease with temperature extremes. Alkaline batteries may leak when used outside the temperature range of -25° to +50°C, or when the battery voltage drops below 9.6 V.

Enclosure Considerations
A desiccated, non-condensing environment is required. The BPALK includes built-in keyhole flanges for mounting to the backplate of a Campbell Scientific enclosure.

The operating voltage is 9.6 to 16 Vdc. The datalogger will shut down at 9.6 Vdc. When this happens, a counter is incremented in the datalogger Status table (low12Vcount). In general, 12 to 14 Vdc is a normal range. Voltages above 16 Vdc could damage the datalogger and cause bad measurements. Therefore, the resulting data should be reviewed carefully. Sustained voltages in excess of 16 Vdc can damage the datalogger and the wiring panel.
