Removing the Endcap
Theendcapmustberemovedtoll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
atheadscrewdriverbyatleastthreefullturns.Thiswillventthegasgeneratedby
Lithium-Ion batteries in use. If the battery pack has a Pressure Release Valve (PRV),
any required venting is done automatically and this step is not required.
b)FullyremovethefourradialM6atheadscrewswitha4mmhexkey.Ensurethese
screws are kept safe as they will be required to reinstall the endcap.
Figure 01: Manual vent plug circled on a JP2-B3 and JP9-B3
Figure 02: Radial screws circled on a battery pack to their show location

JPX Battery Pack User Guide 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.

JPX Battery Pack User Guide 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,ipitupside-down
so the contact plate is facing up.
Figure 04: Battery pack showing feet
placement for end cap removal
NOTE: Once the endcap is removed, the sealing
surfaces are vulnerable to scratches and dents.
Be extremely careful when handling the separate
parts. Damage to the sealing surfaces or O-Rings
can compromise the seal and lead to water ingress
during use.
Figure 05: Battery pack sealing surfaces are shown in red

JPX Battery Pack User Guide 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. All batteries are installed in the same orientation with 6 D-Cell batteries in
each column.
Important: Ensure the batteries are the correct type for your battery pack (alkaline/
lithium) and that the switch is in the correct position prior to installation.
Do not mix battery types (i.e., different manufacturers or different battery chemistries)

JPX Battery Pack User Guide 9
d)Installingbatteriescanbedonebytakingoutallthefoaminsertsandllingeach
individually. Or pushing the batteries down from the top, without taking out foam.
e) Once batteries have been inserted, replace the contact plate A.
f) Hand-tighten the thumb screws into place. This should be done with clean dry hands to
avoid potential minor shocks. Ensure the screws are secure as they complete an electrical
circuit.
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.

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.
NOTE: We recommend replacing the O-rings after every deployment, however if the
O-rings are to be reused, ensure both O-rings are completely wetted with the supplied
O-Ring lubricant. See the O-ring replacement section for instructions on how to properly
replace the O-Rings.
Figure 09: Sealing surface of the battery pack shown in red.
TIP:Usengerstohand-loosenthejacking
screws if using the hex key is challenging.

JPX Battery Pack User Guide 11
b)CarefullyslidetheendcapassemblyintothecanuntiltheO-ringsarejustexposed.
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.

d) Align the four radial retaining holes as best you can. It does not matter which
specicholeontheendcapalignswithaspecicholeonthecan.
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. If it seems to be requiring excessive force, remove the endcap
andverifythejackingscrewsareremovedandnothinginthecanisinterfering.
Figure 12: Radial holes from the end cap and
body circled to show the alignment.

JPX Battery Pack User Guide 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.
g)Usinga4mmhexkey,screwthefourradialM6atheadscrewsintotheradial
retaining holes until snug. The integrity of the seal is not affected by how tight the
screws are, so there is no need to tighten them excessievly.
h)IfthebatterypackisaJP2-B1orJP9-B1,tightentheventplugrmly.Conrmifyour
odel has a vent plug or pressure relief valve and follow the appropriate steps below
i)RemovejackingscrewsbeforedeploymentsandreplacewithM8x20nylongset

JPX Battery Pack User Guide 15
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)
ConrmingVoltages
Avoltmetershouldbeusedtoconrm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).
b) Place the positive voltmeter lead (red) into pin 7 (pinout below).
Fresh Alkaline batteries should measure approximately 27-29 VDC.
Fresh Lithium batteries should measure approximately 21-25 VDC.

JPX Battery Pack User Guide 17
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atheadscrewdriveroracoin.
ii) Slowly turn screw 1/4 turn allow to vent and repeat until open.
 iii)Ifthemodelhasapressurereliefvalve: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 outgassing.
b) Rinse battery pack with fresh water to clean and ensure dry before opening.
c) Before opening follow ALL Maintenance procedures.
Cleaning the Battery Pack
• The outside of the battery pack should be thoroughly rinsed with fresh water after each
deployment to remove saltwater and debris.
• The battery pack should only be opened when it is safe to do so in a clean and dry
environnment without the chance of water entering the inside of the tube.
• Dry the endcap before opening so water does not drip into the tube.
• Use the Removing End Cap for instructions on opening the battery pack.
• O-rings and O-rings surfaces should be cleaned after deployment and replaced if any
abnormalities are seen or felt (see Appendix A).
• Once the pack is opened, visually inspect batteries and tube for leaking or corrosion.
• The inside of the tube should always be kept clean and dry.

JPX Battery Pack User Guide 18
Anodes
The 900-meter battery pack has an anode to minimize corrosion. The battery pack anodes
should be checked and replaced as required after every deployment. It is important that
anodes are monitored closely and are not fully consumed. If the anodes are not maintained
the battery may become damaged and cause catastrophic failure resulting in a void
warranty.
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.
The consumption rate of the anodes depends on many factors (salinity, temperature, water
currents, electrical leakage, etc.). After each deployment the anodes should be checked,
andtheusercangaugethisfrompreviousdeploymentsandadjustthereplacement
schedule as required.
Please contact Ocean Sonics if you require more information on anode replacement or
replacement parts.
Cleaning the Seal
• Clean all O-rings and O-ring surfaces with ‘KimWipes’ or similar lint free tissues.
• Inspect the O-rings to ensure they are seated properly and not damaged.
• Inspect the O-rings surfaces to ensure they are not damaged.
• Lubricate all O-rings and O-ring surfaces.
