Rated 5 out of 5 by from Great price This is the same battery that I bought 9 plus years ago, Even though the warranty is nothing to write home about having the first one last as long as it did,I didn't hesitate picking this one again, plus the price was right.

Rated 4 out of 5 by from Good Lawn & Garden Battery...BUT! The battery I finally purchased at my local store was more than adequate for my ride-on lawn mower. HOWEVER... the first battery I was given by the salesman had a round manufactured date sticker on it dated 9/14! Since I was purchasing it on 5/15 that indicated to us that the battery presented to me was nearly 11 months old already! Since this battery is only warrantied for 1 yr.and it obviously has been sitting around the store for that long a period I asked for one that was newer...say made sometime in 2015. The salesman understood my concerns and promptly contacted another Pep Boys store that had a fresh supply of the same battery dated 4/15. It was sent over the very next day for me to purchase. My advice to everyone is if you're going to put you're hard earned money down to buy something do your homework and be sure to check the date of manufacture on all types of automotive batteries! That goes double if you're thinking of buying tires for your family also have manufacture date codes imprinted on them too! Also, they have EXPIRATION dates when they can no longer be sold because of rubber degradation! CHECK THE INTERNET Those are my "words to the wise."
