Hello, and I will start by saying sorry, as I'm sure this question has been asked many times before. My partner and I are moving into a a narrow boat this month. We are really not sure how often we should charge the batteries on a daily basis with general living aboard in mind.... 12v fridge, lights(all LED), small use of mains with 240v inverter, charging laptop, little bit of t.v, and so on.
We have a 58ft with a beta marine 43 engine. One battery for starting the engine and 3 large batteries for power.
Could someone please have the courtesy of helping a couple of newbies please, and no smart ass comments.
Also is it fine to just have the engine running idle or does it need a bit of juice then charging?
