The GeoMeasure Base Battery Kit is used to power a base receiver in place of internal batteries. Assembled by our team, these kits have been thought through for optimal performance. Pre – attached eyelet cables eliminate the need for alligator clips and the fuss that come with them. The smart charger included ensures the battery isn’t overcharged. We assemble our battery kits with the future in mind; we want them to last, no matter the weather conditions or usage the kits get.
