Rated 2 out of 5 by Battery great - free installatiion was terrible I purchased this battery online & went to my local store to have it installed for free. The service technician struck the radiator overflow return line connection with the battery & broke it off. The technician then proceeded to try and tell me that it came off due to corrosion. The part of the radiator that he broke was high impact plastic on a radiator that was less than 5 years old. I had to take my car to the radiator shop that installed the radiator & get an estimate for a repair to replace one tank on the radiator (the side with the radiator cap). Once I got the estimate, the Service Manager was very kind & admitted their mistake, & credited me the amount of the repair. PepBoys lost money on that sale, but I was happy with the final resolution. I was NOT happy about being lied to by the installation technician, which the manager confirmed in my later conversations with him. March 14, 2014

Rated 5 out of 5 by Excellent value This battery replaced the original Delco in my 08' GMC Envoy Denali . We had some very cold mornings where the old battery was showing it's age by cranking the 5.3 l. V-8 a little slower than normal. This new Bosch is working great and the price was fantastic at $30 off !! December 21, 2013
