I took the battery replacement advice provided by this wonderful forum (thanks Onehundred80) and just used 2 coupon codes for the purchase of the AGM battery from Advance Auto Parts (retailmenot.com (thanks West Peterson) from $174.99, ($50 off), add in the core charge $18 and tax (IL is too high) total is $156 and change. Not bad considering I have been a die hard Sears Auto Diehard battery loyal customer but the warranties on Sears batteries are not what they use to be. Sears was quoting $236 with testing/installation on their AGM Diehard. AGM warranty- only 3 years. (saved $80)Thanks to all!
