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. This pack uses eight AA batteries, which are not included.
Read MoreTechnical 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.
