A reader called to ask: “what batteries do I use for speedlights”?
Good question. And a very important one. Here are my thoughts:
- Bring enough of them. Twice as many as you think you may need. Then some more.
- Ensure that they are charged before the event.
- Swap them often – after every part of every shoot.
And now as for which ones:
- Use NiMH rechargeable batteries. They deliver more current (lower internal resistance while charged) than Alkalines. And they are cheaper since they are reusable.
- Use “low self discharge” batteries. These are marked as such, or they are marked as “ready to use”. Sanyo Eneloops are the most famous battery of this type.
And now for a very important last factor:
Get a conditioning charger, like a LaCrosse or Maha charger (Google; or just try amazon.com). This type of charger can discharge your battery before charging again; doing this every now and tehn ensures your batteries never develop a memory effect; i.e. they will stay better, longer.
I am off to sleep, since for the next three days I speak at the Imaging Show at Mississauga’s International Centre.
