Can using non as Asus cables damage the battery or tablet though?”
There are ways a cable can cause damage. For example...
Asus use their own unique non-standard method of wiring a USB socket so only leads wired to that standard will work. Extremely unlikely they would be that stupid though.
The cable you use is wired incorrectly
The cable is badly made and causes a short circuit to occur
However if the cable is wired to the correct spec and sufficiently well made it makes no difference whether it is an "official" Asus one or not.
