I've just finished my 7th season mowing and plowing with my GT245 and have noticed my battery starting to crank real slow; this is the original battery. My previous experience was similar; I bought a Simplicity new and that battery lasted 6 years. The replacement batteries I bought lasted only 2 years after that. I bought the replacements at Sears, NAPA, Home Depot always with the same result; 2 years and out.
So the question is, am I extremely lucky with the first battery I start with or are the OEM batteries that much better? Is it worth the extra cost of buying from the dealer or I am I better off replacing more often?
