Dark Night Outdoors has extensively tested Tenergy CR123A and are quality replacements for thermal scope use. We always recommend using an external battery pack setup in conjunction with the CR123A Batteries to reduce associated costs. However, you will want to keep some of these on hand as a back-up to external battery pack setups. This is an excellent add-on product when purchasing a scope to reduce shipping costs.*Note - 4 Batteries per pack
