Hi All
Another newbie here.
I have an old boat which is stationary at the moment, and hooked up to a landline. One)brand new leisure battery on constant charge via a 12v battery charger (as recommended by neighbouring boaters). Been fine for months then suddenly - battery dies. Battery charger red light on (for power) but not charging, Went and bought another 115ah battery, checked battery charger, all fine - lights came back on, water pump works again., hurray!
Few weeks go by, lights die, water pump not working. Battery dead. Charger still plugged into mains socket and attached to battery but not charging. My multimeter registered 00 charge!!!
Got out a very old small battery charger 6V and put battery on charge - bingo,it's now charging (I found out from internet about smart chargers not 'recognising' very low/no volts in batteries).
Now what do I do? I have even found out what 'parasitic drain' means and checked that nothing is switched on, but am lost for ideas. Is it something to do with the inverter? (I flipped a switch upwards on it yesterday and the TV went off so I have now put it back down).
I can wire a plug and change a fuse, but other than that, the sum total of my electrical knowledge is written above. (I have impressed myself with having got this far!).
Any advice/suggestions very much appreciated, as I am determined to crack this.
