Depending on your instrument type, it may be equipped with the functionality to use internal batteries or an external battery canister. Please find below a guide on how to open and replace the batteries.
Opening the instrument
To open the instrument, hold the housing in one hand and unscrew the end bell nut by turning it counterclockwise (Step 1)
Remove the end bell (Step 2), by gently pushing or pulling it straight out of the housing (Do not twist).
Pull out the battery cradle from the housing (Step 3).

Changing the batteries
The Aquadopp 2 can accommodate up to either three alkaline 50Wh, three lithium 165Wh or three rechargeable lithium-ion 75Wh batteries.
Do not mix alkaline and lithium batteries!
Start by connecting the battery harness (female) to the 2-pin connectors (male) that are attached to the battery cradle (Step 4). Then, place the new battery into the cradle (Step 5). Finally, tightly secure the battery in place using the attached strap (Step 6). Repeat for up to three batteries.

Closing the instrument
Place the battery cradle back into the housing (Step 7) ensuring that the cradle connector mates with the head connector (Step 8).
The battery cradle only fits one way, and the correct mating is indicated by a visible ring (1 cm) of aluminum (Step 9 & 10).
Gently insert the end bell until it mates with the housing (Step 11).
Gently screw the end bell nut on to the housing by turning it clockwise (Step 12 & 13).

Important Notes
When opening your instrument, carefully inspect all O-rings, the O-ring grooves and their corresponding mating surfaces in the battery housing. Look for any dirt, grit, sand, hair, lint, cuts, tears or any other damage or contamination that could compromise the O-ring seal. Ensure also that every O-ring is correctly seated in its groove and greased. Proper maintenance of the O-rings and sealing surfaces is essential to prevent water ingress and potential instrument damage.
For detailed maintenance instructions about the O-rings, refer to the O-ring care article. If any O-ring or mating surface is contaminated or damaged, follow the maintenance procedure described in that article before reassembling the instrument.
