Rated 5 out of 5 by from Great Overall The battery met OEM Specs for my vehicle (Mercedes E430) for a fraction of the price. I lucked up on a 20% off coupon online as well. Free installation was a plus. Lengthy warranty and Bosch brand sold me on the product. No issues thus far.

Rated 5 out of 5 by from Bosch battery Battery was available as promised, price was excellent. Even though according to Pep Boys battery selector, this was the correct battery for a 2002 Porsche turbo, it actually was slightly larger then the battery mounting location was setup for. Had to pull the bottom of the battery shelf out, mover the mounting bolt to the full end of the battery shelf, and use a thumb screw to secure the battery in place. 10 min fix

Rated 4 out of 5 by from Big, strong battery Big, strong battery. Unfortunately, one of the vent plugs was broken, but I didn't notice until it was installed. Hopefully venting battery fumes into my engine bay will not be a problem.

Rated 5 out of 5 by from Strong power source I drive my Jaguar seldomly and this battery has been seamingly endless at holding it's full charge. I can not comment on durability since I have only had it for about 6 months. However, I only started the car twice in those 6 months and she fired right up with plenty of cranking power.

Rated 5 out of 5 by from Identycal battery to the original it replaced Bosch was the only available battery to offer a vent port like the original Mercedes battery. With the online coupon was also the lowest priced battery I could find. The only drawback was the difficulty of the installation process. I was able to install the battery without removing the hood, however next time I will remove the hood to facilitate the installation.

Rated 5 out of 5 by from Perfect fit Battery was a perfect fit for my 540i. Even the vent line matched up (Battery is stored in truck). Best price around for a 49 series battery and they had it in stock. Of coarse the ultimate proof is how long it lasts. On that I cannot comment.

Rated 5 out of 5 by from Exact fit for '11 Genesis 3.8 Easy to change out, other than the weight of the battery. Connected my battery charger (@ 2amp setting) to terminal clamps, then "hot-swapped" the OEM battery with the Bosch. This kept power for all memory settings, radio, etc. Needed two people to make the move easier (I love my wife!). Everything fit exactly. OEM has 740 CCA, this Bosch has 850CCA, so there was a little extra "kick" when starting car. Been one month now and all is fine. And the warranty (96 months pro-rated and 3 years replacement) is virtually non-existent with other batteries costing $50+ more. Happy with purchase at this point!

Rated 5 out of 5 by from Great Price - Perfect Fit Significant price difference from OEM battery. Battery functions well at almost a 1/3 of dealer price. Easy install. Online coupon sealed the deal for me. PepBoy's online purchasing and store pick-up interface was okay -- never received email from store verifying receiving order - online discount stated had to pick item up the same day. Called store to inquire -- was told just come in. Store Customer Service was adequate.

Rated 5 out of 5 by from Excellent product at a great price! This battery fit perfectly in my 2007 BMW X-3,The vent connected easily to the existing tubing. Although the specs said a smaller battery would work- the original was this size and this battery had higher CCA than the original. Great all around. We just have to check back in 5 years to see how it holds up.

Rated 5 out of 5 by from My second Bosch battery from Pep Boys The battery is in a 2000 BMW. The original car battery lasted nearly 7 years and I replaced it with a Bosch battery from Pep Boys. I have just replaced it after 7 years with another Bosch from Pep Boys as it was getting weaker but I expected it to not do well in the colder weather. So, the old battery did at least as well as the original battery and at a very decent price. The new battery came with an online purchase discount which made it the lowest cost option Fine quality and best price.

Rated 4 out of 5 by from Well known name for car parts. Although I recently purchased this battery my experience with Pep Boys was satisfactory. The workers were knowledgeable and friendly. I wasn't sure about a Bosh battery as it wasn't familiar to me, however, the reviews were mostly positive and since it had a good warranty I thought I would try it. So far so good.

Rated 5 out of 5 by from Perfect 2000 Jag VDP replacement Battery is trunk mounted and finding a size 49 battery with proper venting was an issue. This battery fit and vented fine. It was was also priced considerably lower than comparable batteries. 3 year replacement warranty and 7 year pro-rated seems like a bargain for the price paid. We'll see over time.

Rated 5 out of 5 by from Used to buy die hards! After discovering the warranty on the Bosch batteries and realizing the convenience of purchasing them from Pep Boys it's the only battery I'll buy now! I have bought these batteries for three different vehicles over the last several years and I haven't been let down yet. Buy Bosch!

Rated 5 out of 5 by from Good Deal on a battery I ordered this online for store pickup so I could drop off the core. Fast and easy with the best price I could find anywhere.

Rated 5 out of 5 by from Great value This battery appears to be identical to the MBZ battery I replaced which lasted 7+ years. With a 20% discount it is a great value.

Rated 5 out of 5 by from Perfect OEM Fit and reasonably priced! Looked for OEM replacement for my 2006 BMW 550i. This said it was. When I matched it to my core, it was an inch shorter, but other dimensions the same. Turns out BMW must use multiple suppliers as there are 3 threaded holes in the body structure that the battery base mounting clamp can thread into, accommodating 3 different length batteries! Perfect fit in the middle hole! Better than minimum cold cranking amps, reasonable pricing, and easily replaced! Thanks guys! Steve
