Batteries for Summer Only Enclosure

Rechargeable Batteries

Rechargeable batteries are used for summer-only and year-round polar seismic experiments. For summer-only experiments, due to the roughly continuous sunlight, stations can be powered solely with rechargeable batteries.

For PASSCAL Polar experiments the preferred rechargeable battery is an AGM (Absorbent Glass Mat) battery manufactured by Concorde Battery Corporation. Both the Sun Xtender PVX-420T and PVX-560T work well for a summer deployment where only a limited amount of storage is required for cloudy days.

Primary Batteries

Primary batteries are usually not necessary for summer only deployment due to the ample amount of sunlight available.

 

Batteries for Year Round Polar Programs

Rechargeable batteries:

Rechargeable batteries are used for projects using solar and/or wind charging systems. PASSCAL's Polar Group has used SunXtender AGM batteries by Concord succesfully for many deployments. These batteries, aside from being reliable, offer several advantages. They are sealed and non-spillable, which makes then safer and easier to handle in the field; they have a low self discharge rate, which is important for a low power system, with extended periods of time between charges (arctic conditions); and they are exempt of DOT HazMat requirements (49 CFR Section 173.159) provided that they are shipped in their original package or in a package that satisfies the requirements of 49 CFR 173.159(d).
