Energizer A544 6 Volt Batteries Max Review

These batteries are NOT durable at all. They don't last a full 8 hours on my dog's bark collar. I have a camera installed at home and will be notified when my dog barks. I know she doesn't bark during the day and there shouldn't be a reason I have to change batteries every day. I got more battery life from fake brands. If I could return them I would, review 5 of them and think it was a fluke.
