I've purchased a few Romisen flashlights from Shiningbeam and like them a lot. I'd been using rechargeable AA batteries to power them up until now, but received a free CR123A battery with my last shipment and was very pleased with the light output. Two questions, however, have popped up during my research on the Internet.
1. Is there a preferred vendor for rechargeable CR123A batteries (I believed their often called RCR123A, and are sometimes up to 1mm longer than their non-rechargeable brethren)?
2. Why is the stored power of the rechargeable CR123A batteries approximately half of the non-rechargeable batteries (~750-900 mAh vice ~1400-1500 mAh)?
