Suprisingly, in the time that I've had my X45, I've used alkaline batteries...and a million of them at that. Could someone show me the best rechargable AAAs that I can get for my laser? (preferably not DX because of shipping)
They're a low self-discharge NiMH battery which means they have a long shelf life. They're ideal for laser pointers for other reasons I can't be bothered and probably can't explain anyway.
I haven't tried the Sanyos in my Optotronics 5mW pointer. I have tried the Energizers though and they didn't work very well. I talked to Jack and he said rechargables in general don't work very good with them. The Energizer lithiums work great though.
So far, every laser I have performs better with high power rechargeable NiMHs when compared to alkalines. When you measure both types of batteries with a multimeter in "idle" state, you'll find the alkaline has a higher voltage than the NiMH. But as soon as the batteries need to power a device that requires a high current, the alkaline voltage will drop at a steady rate. The voltage of the NiMH will stay almost the same.
