    Perhaps someone knows, maybe spruce.

    My battery seems not to be charging as quick as usual still, nice and green on the indicator, but where it is usually 12.5 -12.7 topped up by the SCR it is now 12.1 to 12.2

    At present I am hoping I can attribute it to the drop in temperature. I have taken it out for the night and got it on the trickle charge to max it up again but normally I do not have to take it out and put it on charge.

    Any advice.

    How many cycles has it done and is it gel mat or lead acid?

    How many miles are you doing to keep it charged? I don't do a lot of miles, mine charges through the van battery as I drive, but I still put my leisure battery on charge twice a week.

    Couple of hundred a week. It has been sound for six months but last three days (and temp has just dropped sharply here) it has been hovering at a lower voltage.

    These split charge relays, do they reduce the current you're chucking into the battery? Or is it basically coming off the alternator? 14v ish? Should they have some sort of charge controller?
