Rated 4.5 out of 5 by 43 reviewers.
Rated 3 out of 5 by As a battery, it works I needed a series 78 battery for my Chevy Trailblazer. PepBoys said they had one in stock. I picked it up and installed it and then realized that my new battery had both top,and side terminals! How convenient for someone. But not me! The Chevy has a cover for the battery, which obviously doesn't have holes for those new top terminals. And then a steel crossbar that fits over the battery, which would short those unneeded top terminals. Bosch should stick to the specifications of a 78 series battery! November 18, 2016
Rated 5 out of 5 by great price I shopped around for a new battery, my old battery had 15 mo. left on warranty. the old battery was bought at sams club. they no longer offer a 8 yr warranty, that's the reason for my battery purchase November 9, 2016
Rated 1 out of 5 by Poor. I will not go back to Pep Boys for another battery install. I arrived in time for my appointment and my car, a 2001 Buick Century was taken in within half an hour. More than an hour later, I approached the sales rep to ask if my car was ready. After all, it only needed a battery. I was told no, but not given any other information. Almost half an hour later, I inquired again. This time I was told that my car was not starting. And the brand new battery was not taking a jump. I suggested (yes, I suggested) that perhaps it was the starter. After almost another half hour mechanic came and agreed that it might be my starter. I asked the price to replace the starter and was quoted an estimate of between $500-$600. And, the mechanic was not assuring me that the starter was, in fact, the problem. Finally, they got my car started and rang me up for the battery. I noticed that my car was running and asked what would happen if they turned it off. I got a noncommital response. I said to the sales rep, "If I was your Mother or Sister, wouldn't you TELL me to go straight home because the car won't start if I turn it off?" He shrugged. I will NEVER go back there again.

Rated 5 out of 5 by Very Happy with purchase I needed a battery and Pep Boys is very close to home. I ordered online and when I got to the store, the service manager addressed me by name when I walked to the counter. This is my second battery purchase at Pep Boys. The installation was quick and they checked my charging system in my car and all was well. Thank you for the honesty and making me feel good that I chose you for this purchase. I look forward to using you for additional service in the future. Thank you September 21, 2016

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 Very good Battery The battery that the crew from Pepboys is top quality, the crew was Fast in its installation, March 6, 2014
Rated 4 out of 5 by Great deal I got this Battery and it has been great. It never even was affected by all the sub 0 cold we have been having. Thanx Pep Boys. January 25, 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
