Expert Tip: To get the most out of your batteries, always replace the entire set in a device at once. Mixing old and new batteries, or different brands, can cause the cells to drain unevenly and may lead to leakage. For devices that won’t be used for several months, we recommend removing the batteries to ensure the safety of the internal contacts.
