Hi
I have just bought 2 new 110amh batteries to replace the one 5 year old battery that was in the van when I bought it, because I am going to France in a few weeks so want to make sure the van is tiptop.
My understanding is not to use the new batteries with the old battery because the new 110amh batteries will be affected by the old battery, is that right?
I researched to see if it was a straight forward swap. Take old battery out put new battery in, then put 2nd battery in parallel to give me more 12v power. I know positive to positive negative to negative is parallel but I have just been told by my ex trucker brother in law that although the cables are rated as 110amh I should replace them with cables rated above 220amh to accommodate 2x 110amh = 220amh.
Now I don't think thats correct, but if it is will I have to replace all the cables and the split charger in the van to 220amh.
Also I want to use the old battery in the van too with a separate charger thats plugged into a separate 240v plug so it only gets charged when on hookup. For charging laptop and phones and using a 300w inverter. The thinking behind this is that the old battery is still ok to use so use it without affecting the new batteries.
Does this sound too complicated , is there a better use for the old battery?
It goes without saying I am a novice with electrics. So any help is appreciated.
Many thanks Gary
