Ctek250se

[b4daveuk]

Is it ok to use a lead acid battery for the starter battery and an AGM battery for the leisure battery when using a Ctek250se?
Thanks

AGM is still a lead acid, but the acid is in a glass fibre mat.

Differing batteries are fine.

You need to set the leisure to AGM. There is a small black lead on the CTEK that determines the battery type by being earthed or not.

Thank you very much for your help. I have wired it like that but just wondered why the meter I installed was reading 1.2A being used when nothing is on.
I have put two brand new 100Ah AGM batteries in parallel but I think the starter battery needs replacing. Not sure if the 1.2A was being used to charge the starter battery.
I have bought a new starter battery today and see how I get on tomorrow.
