Hearing aid manufacturers have long provided information about their products’ battery usage in the “datasheets” that cover the technical specifications of each hearing aid. As an example, Resound’s datasheet for the Resound LiNX2 LS61 shows that the hearing aid (which uses a size 312 battery) drains 1.3 milli-Amps (mA) from the battery when tested in “test mode” via the ANSI S3.22 standard.
