If you are like me, you have a couple of strobes and plenty of AA batteries. During a shoot you notice a flash loosing power so you swap-out the batteries and throw the old ones in with all your other batteries. Bugger, which ones were charged again?
I went and purchased some battery cases off eBay for a couple of bucks and then printed out this guide provided by Benny Johansson. Just cut out one of the sections and tap it in your battery case. Next time when you pull out a set of de-plenished batteries, orientate them so the positive terminal points to the red end. Then you know they are flat and need recharging once you get home.
After charging, place the batteries in facing towards the green end and you are ready to go to the next photo shoot.
- Tech tip – Keep your batteries together in sets. Try to avoid mixing and matching batteries because they will have different capacities and charge cycles which may affect your devices performance.
