Optima Blues for me too. Plus add a BatteryMinder Charger and plug them in every time you are home. I have had mine 13 months and going strong. Big inverter running big fridge 110% of time, tv, lights, etc. Look at Advance Auto Parts online. Get em with a 15-20% off sale and free shipping. I really had to search their site hard and ended up doing it with a human on their 800 number.
