Where to find 9v batteries

[Jammet]

I've been able to gather a fair number of 9v batteries from zombies in red warning vests in the previous patch. Now these batteries become increasingly important, but the zombies barely have any of these any longer. Has anybody else found a more reliable place on the map to find some?

Well, houses in cities more inland, lots of the green shacks have them in my time, sometimes they spawn in cars, they also can spawn in the markets and stores, along with sheds and hunting towers i think, but that's what ive seen, so weather it will be your luck, im not sure, but that's what ive seen. good luck!

as above also the hand held radios sometimes, in military zones

Mostly in the shelves in industrial spawns like like sheds and garages

I often find some in normal houses.
I sometimes have to drop some on the ground cuz i've got too much ^^
Don't worry, just loot all houses in a little city and i'm sure u'll end with at least 1 or 2 !
Good luck !
