I use the Energizer Lithium AA's in both of my Vivitar 283 flashes as well as my Olympus C5050. Not rechargeable but they seem to last forever and don't lose their charge while sitting in the device for extended periods. Very light in weight too and supposedly will function at temperatures down to -40F, not that I'll ever have occasion to test that particular spec. Still, I've used my C5050 in icy cold weather with no problems at all. Richard
