Everything you need to know about the R230 Dual Battery System
Hi thanks fo rteh information you have posted....do you by any chance have access to the R231 equivalent...probably the same but I suspect the battery format may be AGM and maintenance free for front as well. just want to be sure for charging.....
the parallel charging procedure at the end would be very useful as well.......my user manual says to connect charge leads to teh jump start points but I don't know which setting to use on my Ctek MXS 7 (10 years old and going strong)
