Rated 2 out of 5 by from Thought it was good. Originally thought this was a good battery. Purchased one in 2013, it lasted 30 months and had to be replaced free under the 36 month free replacement. Second battery lasted 6 months. Now on 3rd battery, (charging system checks ok.) Because it was 36 months and 2 weeks from the original purchase date, Pep Boys charged me the prorated cost for next battery plus installation. Had to lay out over $80 because 2 weeks past 36 months for a new battery that was only 6 months old.

Rated 5 out of 5 by from Good brand and well priced There's mo doubt this battery will be good as it's a Bosch. With Internet discounts and local pickup, this battery beats other locally available batteries in price and quality.

Rated 5 out of 5 by from Excellent Battery Had to replace a Honda battery after only 3 years and 40K miles. Wanted something much better and the Consumer Reports reviews liked the Bosch for my car. Pep Boys installed it for free (my wife's car) and I've had it for a few weeks and it starts MUCH better than the OEM battery. The specs were much better and the warranty (full replacement) is excellent.

Rated 3 out of 5 by from The product is great, but... So far the battery is great. As for the service... the guy at the desk was very good. The install took longer than they quoted me. But the big thing is that they did not reconfigure the hybrid monitoring system. So its been a major pain to get that back on line.

Rated 5 out of 5 by from Awesome battery, price and service I purchased a Bosch car battery through Pep Boys on-line at a discounted price (lowest price in my city). After I checked out and paid, the on-line info said that my battery would be ready the next day. However, less than five minutes later I got a call from Pep Boys saying that my battery was ready for pickup. Now that's impressive service! Thirty minutes later I had my new battery.

Rated 5 out of 5 by from Easy DIY install. Takes 5 minutes to do. Turned out I needed a starter after all for the CRV, not a battery issue, but now I'm good for 2-3 years. Haven't received rebate yet after 3 weeks, waiting.
