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.?
