Manual revision 006 Section 5: Routine Maintenance and Calibration SBE 19plus V2

Recharging Optional Nickel-Cadmium Batteries

The Ni-Cad battery pack and charger are no longer available, as of 2011.

1. Remove the battery end cap (end cap without connectors):

A. Wipe the outside of the end cap and housing dry, being careful to

remove any water at the seam between them.

B. Unthread the end cap by rotating counter-clockwise (use a wrench on

the white plastic bar if necessary).

C. Remove any water from the O-ring mating surfaces inside the

housing with a lint-free cloth or tissue.

D. Put the end cap aside, being careful to protect the O-ring from

damage or contamination.

2. Remove the battery pack from the housing:

A. Remove the three Phillips-head machine screws and washers from the

battery cover plate inside the housing.

B. Pull on the plastic tab on the center cord to remove the battery pack

from the housing.

3. Recharge the batteries:

A. Connect the battery charger leads to the battery cover pin jacks,

matching black-to-black and red-to-red (the pin jacks are different

sizes to prevent cross-wiring).

B. Plug the battery charger into a suitable AC mains power source.

C. The red Charge LED on the charger comes on. Recharging takes

approximately 15 hours. When recharging is complete, the yellow

Trickle LED comes on, indicating the charger is providing a

maintenance level charge.

D. Disconnect the battery pack from the charger and the charger from

the power source.

E. Check the voltage at BAT + and BAT – on the battery cover.

It should be approximately 10.8 volts.

4. Reinstall the battery pack in the housing:

A. Align the battery pack with the housing. The posts inside the housing

are not placed symmetrically, so the battery pack fits into the housing

only one way. Looking at the battery bottom cover, note that one

circular cutout is closer to the edge than the others, corresponding to

the post that is closest to the housing.

B. Reinstall the three Phillips-head screws and washers, while pushing

hard on the top of the battery pack to depress the spring contacts at

the bottom of the compartment. The screws must be fully tightened,

or the battery power to the circuitry will be intermittent.

5. Reinstall the battery end cap:

A. Remove any water from the O-rings and mating surfaces with a lint-

free cloth or tissue. Inspect the O-rings and mating surfaces for dirt,

nicks, and cuts. Clean or replace as necessary. Apply a light coat

of O-ring lubricant (Parker Super O Lube) to O-rings and

mating surfaces.

B. Carefully fit the end cap into the housing and rethread the end cap

into place. Use a wrench on the white plastic bar to ensure the

end cap is tightly secured.

Verify that the magnetic switch on the conductivity cell guard is in the Off

position, so the 19plus V2 will be in quiescent (sleep) state.

housing. If you do so, you may

damage the 19plus V2 electronics.
