>Are you using battery adapters or are you dealing with three types of battery systems?
I use multiple battery systems with OEM batteries and choose not to care because trivialities only trigger schizos. Batteries last long enough to be painless. I still have a 2011 Milwaukee battery that holds 3/4 charge and still use every battery I bought since then without issue. (I mark the year of purchase on batteries to keep track of longevity.)
Overthinking batteries is pointless distraction. I have work to do and my cordless tools pay for themselves in the first few uses.

OP is trolling of course since effective task and area lighting means less time spent moving a trash light. I use multiple LED headlamps and leave them around my shops and vehicles since every tool should ideally reside at point of use.
Current labor rates make DIY an increasingly effective financial effectiveness multiplier and decent tools last decades so cost per year ain't shit.
