    The battery is great. Ordering online was the pits! Online order said I could pick this up at a local store in a couple of hours. Ordered and went to the store that evening (30 miles). They didn't have any order. They checked and asked me for a order number. I gave it to them and they couldn't find it. The store manager was nice enough to sell me one outright, honoring the online order price. The next morning I received an email saying I could pick up my battery now. I canceled the order as I already picked it up. This glitch was troublesome and could have been prevented if it weren't for the nice store manager.

              I went and picked this up he same day I placed the order. They taped a receipt over the mfg. date and I didn't notice it until I went to install. Took it back to another store and was told that s battery that old should have never been sold. Got a different size battery and it works very well. Just beware when picking it up and check it over, I have learned my lesson.

              Comments about Optima Batteries BlueTop; Deep Cycle Battery:

              I bought this product to run my boat motor off of. The previous battery, which was a different brand, didnt have nearly enough cranking amps and I would get one good start out of it then it would start getting weak before i had to charge it again. This batter has plenty of cold cranking amps to get the job done, holds a charge very well, and charges very quickly should it even need one. The only thing that is not "ideal" about this battery is that it is a little bulky and a little heavy, comparitively, but that does not make this product receive less than 5 stars. Even though it is a little pricy, it is well worth the money.

                        This Optima Batteries BlueTop; Deep Cycle Battery, Group Size 31, 900 CCA - part# D31M has 2 year free replacement as warranty. Free Replacement Period begins the day of purchase and expires at the end of the Free Replacement Period printed on your original sales receipt. This period does not renew when the battery is replaced during the Free Replacement Period. If the battery becomes defective after the Free Replacement Period and prior to the end of the warranty period, the warranty benefit will be prorated and can either be credited toward the purchase of a new battery or refunded at our option. The proration amount shall be determined by dividing the purchase price by the number of months of the warranty period, then multiplying the result by the months remaining in the warranty period. Partial months are rounded to the nearest whole month. Installation of an automotive battery in any other type of vehicle or equipment voids your warranty. For any further assistance, please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.

                        It is always better to check the specifications before buying the battery. To locate the exact battery, we will need more information including the year, make, model, and engine size of your vehicle before we can make a suggestion.
