I need to calculate how long my battery will last until it is completely discharged. I have a load that will draw 154 uA at 1.8 V for a power of 277.2 mW. Assuming that this is running indefinitely how long will it be until my battery dies? The battery has a nominal voltage of 1.2 V and a rated capacity of 2300 mAh.
I also need to take into consideration that the battery is being charged by a solar panel. Assuming 5 hours of sunlight, and an output power of 93.5 mW from the solar panel.
I found that it would take about 56 days. But this seems really long. Should I just take the battery energy and divide it by how much energy the solar panel give per day?
