batteries - AA Battery capacity


The load is 227mA at 25ms (this is pulled 20times in a minute )and 0.001A for the rest of the time from 4 AA batteries. If this test is running for 20 days, I need to calculate the voltage left on the battery after 18 days.

My calculations for battery capacity are as follows



227mA *25mS + 1mA *2975mS = 8.65mA Typical AA Battery life is 2000mAH Battery hours 2000/8.65= 231hours 20 days is 480 hours 480/231% of battery consumed in 20days? is this right or am I looking at this incorrectly.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
