Having previously run my Raspberry Pi from a set of AA batteries I decided to test all the different types I had available to see which ones lasted the longest.
This wasn’t going to be a scientific test but I wanted a general feeling for how the batteries performed given their different capabilities and price.
The batteries I decided to try were :
- Sanyo eneloop (2000mAh)
- Sanyo eneloop XX (2550mAh)
- 7DayShop Rechargeables (2900mAh)
- 7DayShop “Good to Go” Rechargeables (2150mAh)
- Maxell Alkaline Non-Rechargeables
Due to the time required to run the tests and re-charge the batteries I opted for running the tests with a Raspberry Pi Model B (rev 2) rather than a Model A. Where possible I performed two tests with each set and took the average runtime.
