I have a 99 Eclipse GST. I am on battery number 5,nowan AC Delco Maintenance Free battery, afterthe first four continuously leaked acid from day-one. I bought this car brand new and have never been able to solve the problem. I have hadvery reputable electrical specialists test my car and find nothing wrong. The last word was that the battery sits to high up and at the rear of the engine compartment and does receive sufficient ventilation for cooling. I have no electrical draws or shorts. The Alt and Reg are in line with specs. They find nothing. Just curious, if anybody else has had a similar problem. Thanks for your feedback. Bob
