Every method of purification consumes a resource that will run out eventually. (With the possible exception of boiling, although even there the fuel cost can be an issue.) Filters get clogged. Chemicals run out.

Batteries have the advantage that they can be recharged (eg from car or solar panels), or new ones bought almost anywhere (my Steripen uses AA).
