PENTAX D-BH109 (for k-r, K-30, K-50) AA Battery Holder ② This is a dedicated battery holder that allows the use of AA batteries in the K-50, K-30, and K-r camera models. Due to the manufacturer's discontinuation of sales, it has become very difficult to obtain. It uses four commercially available AA batteries (lithium batteries, nickel-metal hydride rechargeable batteries, alkaline batteries). When using lithium batteries, approximately 1250 shots can be taken without flash. *Personally, I recommend AA lithium batteries. I apologize, but due to its rarity, I will not offer any price reductions. #D-LI109 #D-BH109 #D-BC109 #PENTAX #Pentax #AA alkaline batteries #AA nickel-metal hydride batteries #AA lithium batteries
