Have you called their headquarters in Portland Ore?
One other possibility-Banggood or GearBest sell AAA generic battery holders. If you can't get a brand name replacement, can you use a glue gun and and create a replacement? Is the need for the replacement a broken switch? (I got started down the path of flashlight addiction by Coast/Led Lenser lights my Father in Law gave me for Christmas). I had switches fail on my P7 & T7. Because I had discovered Four Sevens, Olight & Nitecore I never bothered fixing them...Good Luck...
I have always had great success with ledco here in the UK, they maybe able to help out . Even if its sorting a contact your side.:welcome:
