I read that when charging a battery(charger to battery) or battery to battery(I imagine) a toxic chemical/gas is released from the battery. As such you should ventilate and not be in the home whilst battery charges.

I’m going to try the battery to battery method and want to leave it in the car. My concern is the chemicals that come out might get absorbed into the seats or react with something in the car and I will inhale it later etc or it might react with a cleaning chemical etc. Not sure what chemicals come from the battery but is it a concern or after charging for a while with windows closed(as I cant be around for too long)will the chemicals go quickly once u open the windows?

  • In a lead acid battery, hydrogen gas is created during charging, which is highly explosive. Best to charge a battery where there is plenty of ventilation, all my batteries are under the hood in the engine compartment, I leave the hood up when charging. – Moab Oct 3 '20 at 21:56

You should never store or especially service a battery in the home or car. The acids do create toxic gasses and explosions are even possible.

  • Do u mean don’t even put it in the boot or cabin where it’s disconnected?? How are you going to transport it then? – James Wilson Oct 3 '20 at 22:26
  • Transporting and storing are different. Lead acid batteries can do some bad things. AGM batteries are safer because they don't have the acid do deal with. – Jupiter Oct 3 '20 at 23:30
