Examples
Try the starting example
- User-specified usable battery reserve (Ah)
- 30
- Measured constant parked current (mA)
- 50
- Ideal parked duration (hours)
- 600
- Ideal parked duration (days)
- 25
- Daily reserve use (Ah/day)
- 1.2
Try another scenario
- User-specified usable battery reserve (Ah)
- 30
- Measured constant parked current (mA)
- 100
- Ideal parked duration (hours)
- 300
- Ideal parked duration (days)
- 12.5
- Daily reserve use (Ah/day)
- 2.4
Calculation method
Calculation method
Ideal parked duration (hours)
usableAh/(currentMilliamp/1000).
Ideal parked duration (days)
hours/24.
Daily reserve use (Ah/day)
currentMilliamp/1000*24.
Symbols and units
- a
- User-specified usable battery reserve (Ah)
- b
- Measured constant parked current (mA)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Ideal constant-current reserve depletion only; supplied usable reserve is not inferred from nominal battery capacity. Ignores self discharge, temperature, aging, current changes and starting requirements. Supported limits: Usable Ah>0; measured current>0; zero-current duration intentionally unsupported.
