Best value for the price. Made by a first class facility right here in the USA. Shipped directly to me from the factory. Outstanding performance as house and starting batteries on a diesel engine boat.
I bought 2 of these for my boat 2 years ago. Last year the first battery failed and replaced just before the 1 year anniversary. 2nd battery failed yesterday and is beyond the 1 year warranty. Average product life is 1 year, give or take a month or 2.

I use these for off-grid power when the commercial power goes off line. I power three 27" LED Computer Monitors, a Computer, external hard drives and cable/dsl modems via an inverter. These are excellent batteries and well worth the money.
Purchased two years ago, and this DieHard Platinum outlasts and outperforms any battery I've ever had in my boat. Much cheaper than the identical Odyssey PC2150. Virtually maintenance free. I'm buying three more.

I use this as a second battery for my rockford t1500bd my amp pulls 150amps and this battery stays at 14.1-14.4 while my system is on it rests at 12.9V.... My screen name is also my youtube you can see it on my american bass amp too.
Used twice before it died. I am returning to Sears today. If it is not exchanged. Reads less than 5v. Charged on alternate rapid charger as last resort. Will be left at Sears if out of warranty. COMPLETE WASTE OF MONEY!!! Read other reviews to confirm amount of duds on PM1 models
Was the best price I could find for the same size/AGM battery. Picked up at store. But I didn't Pick it UP.... the Clerk there did! And was he shocked at how heavy it was - 75 lbs! When he put it in the back of our work van. It was a bit of a struggle getting it installed. Very Helpful at the store. Great Price. Battery is working great. The AGM is good for rough riding trucks as there are no lead cells to crack or break.

My Sears AGM Platinum Grp 31 battery has lasted 1 yr 3mos of light duty. It has a hard time holding it's charge and over a 4 hour period of fishing falls to `12.4 volts unless I run the 250 Merc from time to time to keep it charged up to to 12.5 or 12.6 volts. At 12.4 volts the engine starts sluggishly. The only thing pulling current is my Lowrance GPS. Sears says the battery is good but O'Reilly Automotive says it has a bad cell. Meanwhile, I am out almost $300.00 with a "Free 3 Year Replacement Warranty." Sears in Fayetteville, Arkansas says they won't replace it unless it says "Bad" on their equipment. Some warranty! Now What!!!!!!
