What milage are you guys seeing these battery leakage problems. From what I have read on here it seems likely to happen it is just a matter of when. Have priced the Optima's and just can't swing them with Christmas wrapping paper still sitting in the garbage can. Still low milage but don't want to press my luck. One of the reasons I sold an 01 Dodge/Cummins is because they couldn't keep batteries in it. At one point I had battery acid all over both fenders, sprayed all inside the engine compartment, etc... What a mess. Paint job was history. Don't want to go through that again.
