We understand over-charging will cause off-gassing of lead-acid batteries, which is the reason why batteries stored inside will need to be vented.
Our question is that if batteries will only be discharged inside the cabin (we can move it outside to charge), could we safely store the
battery inside without venting? For instance, when we are
dry camping, we have an extra utility
battery that we move around to power various things, could we use that
battery inside the cabin at night to charge our phones, laptops, etc.?
Thanks!
