Can I mix old and new batteries?
Do not mix old and new batteries. Doing so will reduce overall performance and may cause battery leakage or rupture. We recommend replacing all batteries within a device.

Does it matter what type of batteries I use in my device?
Always replace the battery or batteries in your equipment with the size and type specified by the manufacturer. Alkaline batteries are often recommended for best performance because zinc carbon batteries have inferior life spans and equipment may not operate properly if zinc carbon batteries are used
