I have just invested in a specific battery for starting the older type of optimax engine (150hp salt water). Reason is that it was thrown on at the end of last year and I used the deep cycle marine battery 110ah which just had not got enough cca to start confidently.
I would like to still use this battery to run all sundries (vhf, stereo, grs, depth, 12v jack charge point) and retain the new battery for just starting. Easy enough to install as I have 2 jockey seats so bags of room for both
Now I am adding a split charge system does it matter that the batteries are different types and specs?
I was pretty sure no issues but wanted to double check. Apart from the split charge kit they are completely independent of each other...
Look forward to any comments / replies
