That is the really neat thing about the Ni Mh batteries. It took a whopping 228 SHOTS AT FULL POWER to kill these super cells!! It went from shooting pretty much normally right to being expired and out of juice. I had the audible alert on the YN560 iii so I would be alerted when the ending was near because you can hear the recycle begin to take a little longer than the previous shots. The remarkable thing about this battery is how it performed right up until that very last flash. It was extremely steady throughout the entire shootout from the very first frames right up until the bitter end where, like all the other batteries tested, it finally was put to sleep by the power hungry Speed Light. The top dog in this competition was the very plain packaged Duracell Rechargeable 2500mAh Battery It is very easy to toss the retired batteries into a bag and pop new ones in but to wait every shot with seconds between each one is just not acceptable. The recycle time is of utmost importance because when shooting an event where your flash speed is critical, we cannot be standing and waiting for our flashes to be ready for that next shot. This was very tedious indeed but I can assure you I sampled each shot around the predetermined intervals (10, 20, 50th, etc) to make sure I was getting very specific results. Using the intervalometer to trigger the flash in a very mechanical, exacting way, I used an electronic stopwatch to record the recycle times. We will get to that and more below but let's get to the testing! Like any other product on the market, there have been some pretty advanced scientific break thru moments that have occurred over the past few years in the rechargeable battery world.įor many years, rechargeable batteries had a bad reputation because they weren't very powerful and they lost their charge very quickly.Īs a matter of fact, just within the last five years there have been some great strides made in the rechargeable battery world.
