Over the years, my passion for photography has taken me all over the world. On professional assignments, I’ve been fortunate enough to shoot exotic, far-flung places and an eclectic mix of people (and animals). But never in my wildest dreams (nightmares?) did I imagine I’d the day taking 750 shots of a blank white wall in my studio. I don’t really know what to do with them all now. Maybe I’ll print them all as an album and create my very own, personalised blank notepad.
So what’s the point? Not everything ‘does what it says on the tin’ and it can pay to put things to the test, instead of just relying on manufacturers’ claims. With that in mind, I’ve been testing different brands of rechargeable AA batteries for Digital Camera World. They all come with a mAh (milli-Amp hour) rating stamped on the barrel, suggesting that some will give longer-lasting performance than others. But how long, and now much longer? And how well do they actually work in the real world?
Armed with a Nikon Speedlight SB-700, a Nikon Z 6II with its built-in intervalometer, a few hours to spare, and multiple mugs of coffee, I set out to discover just what (battery) life was like. I now know that, at its full-power setting, my SB-700 will give me 117 flashes with a basic set of alkaline non-rechargeable batteries, 285 flashes with Powerowl Pro Goldtop rechargeable batteries, and 320 flashes with Panasonic Eneloop Pro rechargeable batteries.
It certainly hasn’t been time wasted. The results mean that we include ‘the science bit’ in our Digital Camera World battery reviews. And on a more personal note, it helps me to know which batteries to pack and which to avoid, next time I’m going on a shoot. I’m just hoping it’ll be something a bit more exciting, perhaps some brick walls with a nice color and a bit of texture.
