There has been another extensive rechargeable AA battery test published. Forum member “SYS” over at the Photography On The Net forum fired his Canon Speedlite 6,560 times to test flash refresh rates,self discharge rates, and the number of flash pops available for various brands of NiMH rechargeable AA batteries. This is an awesome amount of test data and a credit to the photography community.
The ten types of batteries tested were as follows:
Sanyo eneloop “Pre-Charged” – 2000mAh, MAHA Powerex – 2700mAh, MAHA Powerex Imedion “Pre-Charged” – 2100mAh, Rayovac Hybrid “Pre-Charged” – 2000mAh, Rayovac “15-Minute” Rechargeable – 2000mAh, Duracell DX1500 Rechargeable “Pre-Charged” – 2000mAh, Kodak Rechargeable “Pre-Charged” – 2100mAh, Energizer Rechargeable – 2500mAh, La Crosse Rechargeable – 2600mAh, Energizer Max Alkaline – “Use by 2013”
Given that this test was conducted in the USA, some of the tested brands are not available in Australia, however, the significant results are that the Powerex 2700 AA rechargeable batteries provide the faster refresh time than any of the other batteries, and the IMEDION provided the fastest flash refresh time among all the Low discharge (ready to use) AA batteries.
Another significant result is that the Powerex IMEDION AA batteries provided more flash pops that all the other brands of low self discharge (ready to use) AA batteries.
