How Long Will 2 Aa Batteries Last. However other sources do make claims at AA battery lifespans. They last about 450 hours.
If you wish to extend your battery life further 2 battery packs will last. But alas the four AA batteries cant keep that pace. 6 hours 28 minutes.
Discharging a battery to 50 and charging it up to 100 would only be counted as 12 life cycle.
Powering the Arduino from a 9V battery is a waste since about 40 of the energy will get dissipated by the 5V power. Ad We Did The Research For You. Powering the Arduino from a 9V battery is a waste since about 40 of the energy will get dissipated by the 5V power. From remotes to clocks to phones if there is an electronic device to be had it is probably powered by one or two AA batteries.
