Coach Battery Compartment and Battery Upgrades

M_MINCEY · Post by **M_MINCEY** » August 22nd, 2021, 12:51 pm

For the last month or so I've been doing some needed upgrades to the Chinook:

Coach Battery Compartment Latch replacements
Replace/upgrade coach batteries terminals and wiring
Upgrade Coach batteries from Wet to Dry AGM's

For starters, being from Long Island, NY there isn’t many reliable RV repair shops I would trust to work on my vehicle. Bad experiences in the past, so I'm force to work on it myself to the best of my ability.

NOTE: More images to come for this project.

New copper terminals replacements and pre-batteries installations. Using 125AH Deep Cycle AGM Batteries:

NOTE: Ensure that your charger converter power supply is able to charge AGM batteries (Absorbed Glass Mat) because of the voltage differences.

My project is completed, when replacing the battery compartment latch. The original latch was shaped a little different than the new version. So I had to reshape the original battery compartment cutout to fit the new latch. I may have over reshaped the cutout, so with a little rubber and silicone I made a tight waterproof seal around the latch. This will work for now, I may revisit it later on:
