Is it safe to mix different types of batteries?

Mixing a zinc battery (Philips LongLife) with an alkaline battery (Philips Power Alkaline, Ultra Alkaline or Premium Alkaline) will not improve device performance. In fact, it will reduce performance and may even damage your device or cause battery leakage or rupture.
