House Battery Bank Replacement

Replaced the house bank over the weekend. Decided to buy local and replace the 9 year old batteries with exact replacements from Dyno, their D125.

Thursday

  • Created a diagram of all the cables.
  • Labeled and removed all of the cables.
  • Removed 6 of the 8 batteries and carted them up to the marina hazardous waste shed.
  • Removed 3 of the 4 battery boxes.
Friday
  • Purchased 8 new batteries from Dyno.
  • Carted the batteries down to the boat.
  • Removed the two remaining batteries and box.
    • Note, the Trace inverter/charger doesn't work (ie doesn't pass through shore power) when it detects no batteries!
  • Cleaned up the boxes.
  • Cleaned up the bilge area.
  • Painted the bilge area with Interlux Bilge Kote.
Saturday
  • Cleaned up and brushed the cables (lacquer thinner).
Sunday
  • Installed the boxes (3M 5200 under the screws).
  • Installed the batteries.
  • Cabled everything.
  • Sprayed liquid electrical tape on all exposed metal connections.
  • Power on, 12V works, inverter works, through-AC works!
