An inexpensive battery tester was designed and fabricated to measure the capacity of a serial of commercially available AA batteries in the laboratory. The key component was a potential auto logger.  Several brands and types of batteries were investigated.  Their performance in terms of energy capacity, effective energy capacity, and energy density were calculated.  The results will provide guidance to common battery users and raise the awareness of environmental sustainability as well.
