Operating temperature range for Mobilfluid 424™ is
-40 degrees F ~ 180 degrees F (-40 degrees C ~ 82 degrees C).

Geoprobe Systems® uses a 12 volt 1,000 CCA top post battery to power our units. (CCA stands for Cold Cranking Amps.) You can go with a higher rated CCA battery if you would like. Be sure to take a measurement of the height, width, and length of the existing battery in your unit. It is important that the new battery is the correct-sized battery dimensionally in order for it to fit in the location it was designed to go in as well as work with the battery tie downs provided for it.
