•Energizer recommends the use of either Gamma Ray or ethylene oxide (EtO) for battery sterilization.

•In general, primary batteries need to be kept within a temperature range of approximately 0ºC to 55ºC during the sterilization process in order to preserve performance and reliability. This eliminates autoclaving as a recommended method for battery sterilization.

•Gamma Ray and EtO methods have been used for the sterilization of batteries by the medical field for many years.
