i have been using rechargable cr123’s for around 9 months now.
I will never last as long as the normal batteries, but they work ok.
I haev always got one spare so as soon as i get the “station 1 low battery” message up, the spare is charged and later that day, i swap them over.
I do however have a leaking “supercap” in my ISS, and soil station. Remote anemometer is fine at the moment.
I am hoping using rechargeables hasn’t caused the leaks
