Ours were 170ah and we had three of them. Just lately they were ending up flat every morning even after a decent charge the evening before and just a couple of hours watching TV so obviously not holding the charge that was going into them. Anyway the replacements were going to be a normal terminal layout against the 170`s having both neg and pos terminals at the same end. So much easier to obtain and cheaper. The reason we went into the marina to have the job done was the sheer weight of the old batteries (80lbs) and their awkward to get at location. Second reason was the need for some new cables to be made up. My main worry was getting a hernia in the area of my stoma, something I was warned about in hospital could happen if I tried to lift/push heavy things. An hours labour charge and the fact I did not have to source the batteries was well worth it although I would have been so happy to have done the job myself if my fitness level was higher.
The batteries were just two years old and should have lasted longer but we believe a stupid accident a while back cut their life span significantly.
We were coming through Harecastle tunnel and had the washing machine on. Now for those not aware of how boat electrics work this meant we had an inverter running during the wash. The inverter converts the 12volts into 230volts for mains powered appliances like washing machines. Now on board we have an electric mains water heater. This is generally used when hooked up to a mains electric shoreline so would not be used by us when out cruising. Our hot water comes from the engine or our central heating boiler. Some boats can use a mains electric type of water heater on the move but let`s just stick with our set up on Nb Valerie.
So we have the inverter on running the washing machine. Anything running on mains electric does so via the inverter including the water heater. Now as we cruised along one of us went down into the boat and in doing so brushed against the switch panel and activated the water heater. This in turn caused the inverter to work hard pulling a lot/most of the 12 volt power from the batteries to feed the water heaters high power consumption. I noticed something wrong when we exited the tunnel and saw the huge discharge showing on the volt meter. So from this day the batteries were weakened. The addition, soon after this incident, of our large solar panel probably hugely shielded signs of the weakening batteries.
Sorry fellow boaters that was a bit long but I needed to make all clear to non boaters.
As the title says we moved away from the medical mooring Wednesday. Set off along the summit level heading for Marsworth and the Tring reservoirs. The video below was made by the two happiest boaters on the move that day. It might not be anything special to you readers but to us it was like the news film showing Mandela walking to freedom or the the people breaking through the Berlin wall.
We shared the locks each taking a turn on windlass and tiller. Just by not trying to be clever I found the lock gear winding fine if taken slowly.
Moored up alongside the Startops reservoir last night was amazing. The high winds coming over the reservoir buffeted the boat and the rain beating down on the roof formed a musical accompaniment. Snuggled up in bed it was a wonderful way to fall asleep after a very special day.
