I've got an old UPS for which I bought a new battery. The new battery is different in size (longer). Thus it doesn't fit in the structure.
However, if I keep the new battery vertically, I can manage to squeeze it in. But with it tilted, the contacts are not on top anymore (obviously) :)
My question is, if it's safe to keep the battery in this position. We know for example, car batteries shouldn't be used in different angles because of some liquid in it.
So is this ok or are there any threats/dangers?
