I originally switched from Alkaline to lithium around 2011 timeframe. Spent thousands on them until two years ago when I switched everything over to rechargeable. Haven’t spent a penny since then. Have a 5200 mAh battery pack I carry on day trips and another 10,000 mAh I can add for longer trips. GPS (if I use it), phone, headlamp, inReach all use the same rechargeable if I run out in the field, and they recharge from a standard outlet anywhere. 2 way radio is the only item I haven’t switched over because I don’t use it that often and 4 AAA last a couple years. Never seen lithium’s at Costco but I will look now for trail cameras. Batteries leaking alone is worth the cost on those.
