5. Remove the foam coverings to expose the battery harness.
6. Remove the two nut, lock washer and flat washer pairs securing the regulator bracket to the battery
mount posts (threaded rod).
7. Using caution to avoid short-circuiting the battery terminals to the walls of the buoy well,
use a 10mm socket wrench to remove the regulator’s ring terminals from the battery. Set aside the
terminal bolts for use later.
8. Lift the regulator bracket off of the threaded rod and remove it from the data well. The battery
should now be accessible.
[Only for systems with 2 or more batteries]
1. Carefully remove one of the two ring terminal cables connected to the battery using a 10mm socket
wrench. Immediately cover the loose cable end with electrical tape to prevent it from
contacting the data well and short-circuiting.
a. Repeat this step for the other battery terminal and cable, removing the old batteries one by one
as they are freed.
2. Remove the used battery from the data well. It may be necessary to remove some of the wedged
foam surrounding it in the event it does not easily lift out.
3. Remove the ring terminal cables from the original battery terminals using a 10mm socket wrench.
Keep the terminal bolts and re-use them in the new battery.
New Battery Installation
1. [For systems with a single battery]
a. Lower the new battery into the data well. It may be necessary to adjust the foam for a proper
fit.
b. Skip ahead to Step 3 “For All Systems”
