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.

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.

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.

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.

TIP:Usengerstohand-loosenthejacking
screws if using the hex key is challenging.
