| new house batteries (left, 2x73Ah), starter battery (right, 160Ah) |
Replaced the aging house batteries with brand new Westmarine gel batteries. The old ones wouldn't hold any charge for more than a few days so I decided to replace them. The overall capacity is now somewhat smaller (146Ah vs. 320Ah before), but I went through the calculation, should be still fine to run a full night with navigation lights, navigation system and radio on, without going below 80% charge. To be safe I will replace the masthead tricolor with an LED and change the interior lights to LED as well.
The batteries are placed underneath the companionway on our boat. That way they are easy accessible from the quarterberth, and are high enough above the water to prevent shorting in case there is a water leak. The drain pipe above is from the kitchen sink and the refrigerator compartment. The yellow cables are from the Xantrex shore power unit. Also hooked directly to the house battery without any switch is the bilge pump and the VHF radio.
