Why does the PA system eats car batteries now?

Why does the PA system eats car batteries now? I havent used the PA for some time, last time i used it was on 1.16 i think, the PAs had a slot in the inventory and you could put a battery there as well as take the battery back. Now they seem to not have that slot and i found no way of getting the battery back, moreover i couldnt put a new battery in when the battery that was already there got depleted. I can understand making PAs harder to abuse, but why do it in such a stupid and realistic way? Make it take more parts to fix, like a battery, some wiring, maybe a microchip of some sort (those items would have to be added to the game, obviously), but stop it from eating batteries.
