As far as I know, when a player uses hold on a structure already affected by it to unhold that structure manually, it doesn't register as breaking the hold for charge stone. This allows for completing the charge-up for charge stone after a structure has been unheld, whether it is the player with charge stone that unholds it or the opponent is the one who unheld the structure. Also, unholding not registering as breaking the hold allows for a charge to be retained on the player, to still be spent on their next hit-modifer on a structure, while not having an active hold on a structure. From my understanding, this is the current behavior that allows for the technique known as "Charged Battery" or "Charge Battery". In addition to the previously mentioned behavior, there are also things related to Charg(ed) Battery about "negative charges". Perhaps someone can leave a comment further detailing it, but I believe this negative charge behavior is what is referred to here: https://rumble.canny.io/bug-reports/p/charge-not-charging For a suggestion on integrating Charg(ed) Battery as an intentional feature and lingering buff, please see this suggestion (and I particularly recommend the comment chains involving Musical-Memoirs and L3mmi05/Val): https://rumble.canny.io/suggestions/p/integration-of-charge-battery-behavior-as-a-lingering-buff-for-charge-stone
