About the service

We are here to help you save money vs expensive PLB/Personal Locator Beacon, EPIRB, and other beacon battery replacement services.

First some important things to know:

These replacement packs are for replacement of EXPIRED batteries only. If your device has been activated, it will need to be factory reset..

We use high quality parts and packs are built to exceed OEM quality. We use the same or better battery cells, we use thicker/stronger weld strips and stronger welds.

How do we build the battery packs

We start with OEM or better battery cells. They are welded together using welding strips that are thicker and stronger than OEM. We use the same Molex connectors as factory and solder connector wires to welded soldering tabs on the battery. Next using tape/glue we set wires and shield and potential areas that may rub and expose a wire core. Then we shrink wrap the pack. Finally, we run a self test on an actual beacon we have in the shop.


Shipping to you is free, whether you order a pre-built battery or choose to have us replace it for you. Ship to us however you like, we’ll do the work and ship back for free. We include a new battery expiration sticker to affix to you beacon.

Turn around time

Pre-built user replaceable battery packs will be shipped same or next day in most cases. If you send in your beacon for service we generally ship back 2-3 days after receipt.
