Hi Carol, Andy is absolutely right for the majority of customers, where their batteries are behaving according to spec. The units come calibrated from the factory, and it is not necessary to calibrate that often. Obviously we'll continue to work with you privately on the battery issues you're having and certainly appreciate your help and patience. Jonathan Mosen BrailleNote Product Marketing Manager HumanWare
