Is It Safe To Charge Car Battery Indoors. If you are rushed for time dont charge your battery inside. While there is certainly a lack of ventilation it does have an hvac register which doesnt prevent the crawl space from smelling like standing ground water when there are a few inches in the pit.
Indoor charging is not much different from charging the battery outdoors. Should the worst happen an exploding battery is a deadly thing apart from spraying acid over everything and everybody in range. At the pack level the voltage range is between 111 V and 132 V.
In a huge area like a garage 1 battery wont be trouble.
However take precautions. Charging batteries in a cupboard with no ventilation in your home is far from ideal hydrogen is the most volatile of gases explosive range is 5-75 volume in air meaning any significant release of hydrogen is almost certainly going to become an explosive mix of fuel air. The best way to charge a battery indoors is with the minimum amount of amperage over the longest possible time. Battery charging must be carried out in very well ventilated areas and most certainly away from family.
