I use rechargeables as well in all the sizes. Bought these last week. Seem to last longer than the Energizers. https://www.amazon.com/gp/aw/d/B08B4SCCPY?psc=1&ref=ppx_pop_mob_b_asin_title
For you guys that are using rechargeable batteries. How long are you getting out of them if say you are are using them in a headlamp or whatever else?
