The following video outlines how to change the Oyster batteries, which is the same for each of the Oyster, Oyster2 and Oyster3 devices. Note: only replace the Oyster batteries with AA Energizer Lithium batteries.
The device must be sealed carefully to achieve the IP-67 rating.
- Remove all 6 screws.
- Ensure the silicon seal is in good condition.
- Remove the old batteries and replace with 3 new AA Energizer Lithium batteries. The device will blink as it connects in to the network and should update accordingly in your database.
- Replace the lid (the foam helps to keep the batteries in place) and gently squeeze it shut.
- Tighten the screws, starting with those which are opposite each other in order until uniform tightness is achieved. This helps to help prevent cracks from uneven pressure. The screws may be quite stiff the first time you do this.
When sealing, we are looking for: Even pressure along all points of the silicone seal AND an even gap of about 1mm between the lid and base.
If you purchased your Oyster3 with one of our weatherproof magnetic enclosures, you will need to open this first before you can start the process to change the Oyster batteries.
Remove the 4 screws located at each corner of the waterproof casing. You do not need to remove the locking nuts holding the magnets in place.
