I think the SX Pro dongle uses "Super Capacitors"
As far I know they need to be charged often and hold the charge less, but get charged by the Switch. https://gbatemp.net/review/xecuter-sx-os-dongle-update.816/
My RCM Loader was buy on 2018 and since then I really need to full charge before use only one time, hope the battery will stand on good condition for a while.
