The battery is meant to prevent the player from staying on the same floor for too long.
There's no way to recharge it mid-floor. It gets fully recharged after you enter the next floor.
You shouldn't linger in a floor because, after the battery runs out, the floor gets much darker and ghosts from every floor will spawn endlessly (after the room is cleared normally)
yeah, I figured that much, just thought it was weird how I make it to the next floor still in Darkness... turns out it was bugged I had to delete the "save". bc everything was fine at first everytime I started over but time kept ticking after the 3rd or 4th floor no more light, I would just run out of light what seemed like a desert and forest after a few hours walking through Darkness I said this can't be right I notice the ghost in the Extra's wasn't being erased after starting over. I just deleted the save and well there was the problem when I went to the 3rd to 5th floor I had 3 bars in my light, and I can finally have a few steps to breath and enjoy the scenery, I believe what may had happen was (a few Options) a save on death or a error on boss at the same time... first time before the "for ever black out" I made it to some bee boss but died while fighting it, my lights ran out while fighting it, then I believe I left the game accidentally and made 2 windows open the game twice... which may have messed with the save... I have no idea if thats what the cause was but I can just state the Action before it happened... but started over with a new save and game is running fine. so far... I also learnt how to eat them.
