As a way to promote their Powerex 2700 mAh AA rechargeable batteries, Maha Energy has shared an interesting infographic detailing how effective rechargeable batteries are compared to their alkaline counterparts.
As a disclaimer, it’s worth noting that the numbers provided in the infographic were derived from testing done by Maha Energy, meaning it wasn’t a third-party doing the testing.
If you can either look past that aspect or trust Maha Energy’s testing, then it serves as a great look into why rechargeable batteries don’t only save time, energy and money, but also the environment by reducing the need to continually dispose of batteries.
According to the chart, rechargeable batteries, on average, are capable of firing roughly twice as many speed light flashes than their alkaline counterparts. Furthermore, rechargeable batteries offer far faster recycling time, especially as time goes on and the battery power dies out.
Maha Energy says photographers waste, on average, 50 lbs of alkaline batteries. This information is based on each alkaline battery weighing 1 oz with 768 batteries per year. If 768 batteries sounds strangely specific, it’s the result of Maha Energy’s assumption that you shoot with a 4-flash system at 24 weddings a year, with each wedding needing approximately 400 flash firings.
