Description
Calculate nominal supplied battery charge use and remaining charge.
Hearing records depend on frequency, laterality, masking status, calibration and level reference. A no-response label differs from a measured threshold, while an air-minus-bone gap requires comparable test conditions. Device charge arithmetic and scalar signal offsets do not establish hearing status or suitable care.
Calculate nominal supplied battery charge use and remaining charge.
When to use this tool
Use Hearing Aid Battery Consumption Step when you already have openingMilliampHours, currentMilliamps, operatingHours and need to calculate nominal supplied battery charge use and remaining charge.
How to use the tool and how it works
- Enter openingMilliampHours, currentMilliamps, operatingHours. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read consumedMilliampHours, remainingMilliampHours. Use the output convention below.
Require opening charge, current and hours>=0; consumed=current*hours in mAh and remaining=opening-consumed.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| openingMilliampHours | Opening Milliamp Hours | Required. Finite number; minimum 0. |
| currentMilliamps | Current Milliamps | Required. Finite number; minimum 0. |
| operatingHours | Operating Hours | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| consumedMilliampHours | Consumed Milliamp Hours | Required. Finite number. |
| remainingMilliampHours | Remaining Milliamp Hours | Required. Finite number. |

}Limitations and assumptions
- Negative remaining charge is retained as a discrepancy. Constant or mean current is assumed; no real capacity, runtime, discharge curve or device readiness is established.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review original audiograms, instrument settings, test records and the complete clinical context. Use an appropriate professional assessment for interpretation; local unit conversions and supplied labels do not choose tests, presentation levels or intervention.
