I’ve seen many discussions in regard to an ideal battery for the XJS - lots of talk about venting, dimensions, poles in the correct place, explosions, rust, ect. Unless I’m missing something why wouldn’t everyone just order the OEM Jaguar battery for the XJS? It’s gonna fit, it’s vented - everything as it needs to be. Is it a lousy battery in general? Or is there another problem? It can be ordered from SNG Barratt or it looks like Jaguar dealerships can order it to be picked up. The price is pretty comparable to other vented batteries so price point shouldn’t be an issue. What gives? Seems like it should be end of the discussion?
