100G Datalogging ERT Module: Achieving a 20-Year Battery Life


For natural gas and combination utilities deploying automated meter reading (AMR) technology, battery longevity and frequency of required battery change-outs in radio frequency (RF)-based endpoints can make a dramatic difference in the cost of system deployment and operation.

Given these variables, the difference between having to do multiple battery change-outs over a 20-year product life is nothing short of dramatic. Add in the customer inconvenience and the implications of a battery change-out become clear. After all, the purpose of AMR is to eliminate the need to visit the meter.

This white paper is meant to address the battery life of Itron’s 100G Datalogging ERT® Module. It will provide a high-level technical overview of battery life determination for the module’s predecessor, the 100G Gas ERT Module. It serves to provide technical insight in determining allowable current levels for 20-year operation and variances between the first release of the 100G, which contained two cells, and the subsequent release of the 100G Datalogging module, which contains one cell. It will speak to several major and minor design improvements in the 100G Datalogging ERT Module that make a one-cell solution realizable, while maintaining a 20-year battery life.

Itron will be implementing a 100G Datalogging ERT Module battery field monitoring program. Customers can use data presented in this white paper along with future field data to manage their AMR systems more cost-effectively, and time the change-outs of their modules.
