Just wondering if anyone has fitted a optima battery in their engine bay and if they have what one was it?

if you fit an optima as a replacement starter and solo powering system i beleive its a red top you need to use.

if its an adddition and part of a split charge specifically for the audio system then a yellow top is the right one.

although they are both liquid gel batteries, the properties of each are slightly different although memory fails me as to why.
