| All orders are shipped next working day using Royal Mail Tracked 48. Need it quicker? Upgrade to Tracked 24 for priority handling and delivery usually within 1-2 working days. | Please compare the battery part number, connector arrangement and locator beacon model with the battery currently fitted before ordering. | Emergency beacon battery packs are supplied with an expiry-date sticker. This reflects the recommended next service of the locator beacon device, not the shelf life of the battery pack. During servicing, apply a small amount of silicone grease to the cleaned gasket or O-ring as specified by the beacon manufacturer. |
