A question on the battery compartment mod

so while i know what the mod uses as power but i have a question do i get the battery back after the charge is used? because those batteries can be recharged so it being lost would make no sense.

Yes, you can unload the car or storage battery from the tool and recharge it.

cool never used the mod mostly ethier use other and just skip over it or never survived long enough to use it.
got a few ways to charge the batteries so it may be useful later

I tend to use them a lot. Easier than constantly hunting for batteries.
