If a light is for daily use I like rechargeable with ultimate lithium in a bag for backup. If a light is to be kept with a kit, then it is only ultimate lithium for me. If a light has a non replaceable battery, its pretty much a hard no buy for me. Plus I have a few llights that have ithium polymer batteries that I regret buying. The lith-poly batteries will not hold a charge for longer than 3 weeks in my experience. Have you found this to be the case?
@OregonMike - Replaceable batteries are one of my top features. I also use Lithium in any light that takes AA or AAA. I have not had any issues with the Lithium-Polymer batteries holding a charge in my Olight Arkfelds. I just checked my Arkfeld Flex I keep in my car, and it has 4 bars after 4+ months of sitting in car. My daily carry Arkfeld Pro has had no issues either.
