Page 3: Introduction
Welcome to the JPX Battery Pack User Guide—a comprehensive resource designed to empower you with the knowledge and confidence to make the most of your portable power solution. The Ocean Sonics JPX Battery Pack is a submersible unit that provides additional power to one or more hydrophones for long-term deployments. The pack uses a maximum of 72 D-cell batteries that are field-changeable and can provide power for one hydrophone for 30-90 days*. All battery packs are made of lightweight glass fiber composite case. There... -

Removing the Endcap The endcap must be removed to fill the battery pack with the D-Cell batteries or to replace the depleted batteries. When replacing the batteries, ensure the outside of the battery pack is completely dry before removing the endcap to reduce the risk of water droplets falling inside the battery pack. a) If the battery pack has a manual vent plug (shown below), loosen the vent with a flat head screwdriver by at least three full turns. This will vent the gas generated by Lithium-Ion batteries in use. - Page 6 c) Using a 4mm hex key, tighten the jacking screws in the endcap to overcome the friction in the O-Ring seal. NOTE: Alternate tightening each jacking screw every turn. Tightening one jacking screw too much more than the other will apply uneven loads to the sealing surface and may damage the seal. Figure 03: Jacking screws circled WARNING: Soft point screws must be used to lift the endcap. Failure to do so can generate wear particles that compromise the sealing interface.
- Page 7 d) Once one O-ring is visible, the endcap may be grasped by the handles and pulled straight out of the can. The feet protrude slightly from under the can, and they may be used as footholds to help separate the endcap from the can. If the endcap cannot be removed easily, tighten the jacking screws in order to separate the endcap from the can until the second O-Ring is visible. Once the endcap is removed, flip it upside-down so the contact plate is facing up.
- Page 8 Installing New Batteries a) Loosen the 3 thumb screws on contact plate A until it can be separated from the assembly. b) Carefully remove contact plate A from the assembly exposing the 12 battery columns. Figure 06: Contact Plate A, showing closed (left) and opened (right) c) Install batteries in the correct orientation as indicated by the sticker on the side of contact plate A.

Page 9: Installing New Batteries
Important: Ensure all batteries are installed in the same orientation. Failure to do so can result in irreversible damage to the contact plate and battery pack. d) Installing batteries can be done by taking out all the foam inserts and filling each individually. Or pushing the batteries down from the top, without taking out foam. Figure 07: Direction of batteries in foam inserts e) Once batteries have been inserted, replace the contact plate A. -
Page 10: Replacing The Endcap
Replacing the Endcap Before replacing the endcap, ensure that both sealing surfaces are immaculately clean. A single grain of sand is enough to scratch the sealing surface and compromise the O-ring seal! (See Cleaning the Seal under Maintenance) a) Back out all jacking screws from the endcap so they are no longer protruding below the endcap as seen in Figure 9. TIP: Use fingers to hand-loosen the jacking screws if using the hex key is challenging. - Page 11 b) Carefully slide the endcap assembly into the can until the O-rings are just exposed. Figure 10: Endcap replacement onto battery can. c) If the battery pack has a manual venting plug, open the vent plug with at least three counterclockwise turns. Figure 11: Manual venting plug circled on the JP2-B3 and JP9-B3. JPX Battery Pack User Guide...
- Page 12 d) Align the four radial retaining holes as best you can. It does not matter which specific hole on the endcap aligns with a specific hole on the can. Figure 12: Radial holes from the end cap and body circled to show the alignment. e) Push the endcap all the way in. Some bodyweight may be required to push the endcap home, however provided the O-rings are properly lubricated, it should not require excessive force.
- Page 13 f) Observe one of the four radial holes and ensure the clearance hole is aligned with the threaded hole. Do note use the fastener to align the two holes. The endcap should be able to be twisted to align the two holes fairly closely. Figure 13: Radial screw holes that are properly aligned TIP: Do not over tighten the radial M6 flat head screws as it will damage the threads.

Page 14: Opening And Closing The Vent Plug
Opening and Closing the Vent Plug Always close the vent plug for deployment. Ensure the vent plug is in the closed position and fully seated against the face of the endcap (as seen below). NOTE: The Vent Plug can be adjusted with the use of a flat head screwdriver or a coin. Figure 14: Vent plug direction showing open and closed positioning JPX Battery Pack User Guide... -
Page 15: Opening The Pressure Relief Valve
Pressure Relief Valve Directions Do NOT adjust the Pressure Relief Valve. Manual venting is not required. A pressure relief valve will automatically vent to protect against accidental overpressure from battery outgrassing. NOTE: If you are redeploying the battery pack, check the anode (see Anodes section below) Confirming Voltages A voltmeter should be used to confirm the proper voltage is being supplied to the exterior bulkhead connector. a) Place the negative voltmeter lead (black) into pin 1 of the MCBH8F bulkhead connector on the battery pack end cap for the common connection (pinout below). -
Page 16: Deployment
Deploying the Battery Pack The battery pack is now ready to provide power to your hydrophone(s) for your deployment. a) Use the icListen Quick Start to setup icListen for deployment, set the time on the hydrophone, sampling rates and duty cycling if needed (See Appendix B) b) Once the hydrophone is recording or set to record in the future, unplug the hydrophone from the test cable and connect to the battery pack. -
Page 17: Recovery Of The Battery Pack
Recovery of the Battery Pack a) After recovery, inspect for damage and vent the Battery Pack to equalize pressure if the model has a vent plug. i) If the model has a vent plug: manual venting can be done with the use of the vent plug located on the face of the end cap. The vent plug can be adjusted with the use of a flat head screwdriver or a coin. -
Page 18: Anodes
Ocean Sonics suggests replacing the anodes before 25% remaining. If the battery pack is being deployed on a long deployment, it is recommended that you have fresh anodes. -
Page 19: Appendix A: O-Ring Replacement Instructions
APPENDIX A: O-Ring Replacement Instructions 1. Carefully remove used O-rings using a plastic O-ring pick. 2. Thoroughly clean grooves in end cap using lint-free wipes and isopropyl alcohol. 3. Inspect grooves for damage, scratches and debris. 4. Carefully clean and inspect new O-rings and backup rings prior to installation. 5. -
