Technical Specifications

Why Choose Original FOIF BT82?

Using authentic or high-spec BT82 replacements ensures that your total station's EDM (Electronic Distance Measurement) receives the precise, noise-free voltage it needs. Lower-quality generic batteries can cause fluctuations that might affect your measurement precision or even damage the instrument's sensitive internal motherboard.
