Hello, have in my Express (1998, 5.7, petrol + LPG) installed at the moment a Varta Black ProMotive (H9, 12V, 100AH, 720A), which unfortunately after approx. 2 years already gives up the mind so slowly. I was in a workshop by mistake deep discharge (but I couldn’t prove it) and since then it doesn’t want to be so right. Anyway, I don’t want to get angry with them, but simply a new battery. What can you recommend? Can I also easily to the AGM models of Exide ZB Exide EK950 AGM-Battery 95Ah or VARTA G14 Silver Dynamic AGM 595 901 085 Autobattery 95Ah? I know here are much the Optima recommended, but they are also price again significantly more expensive. Best regards!
