Since I can't get a Sear Diehard P1 in Canada and the original Odessey was fracking expensive here.... I buy a Deka AGM "Intimidator" clone under the name NGT Extreme (9A34-785cca) at Carquest. I think you can get the same battery at NAPA sold under another name.
East Penn is a American compagny and the quality as never been a issue, they fabricate AGM for big name parts resellers under many names... They are the best third choice after a Diehard Platinum 1 and a Odessey to my knowledge. I use them on solar system with great result, now I try one in my Jeep this winter (-20f were I live somtime) We will see...

The best AGM deal on the market is and still the Die Hard P1 indeed because they got the same quality contruction Odessey is know for but for less money.

I was finding my CRD slow to start on cold mornings. Decided to check the battery and found that the previous owner (or dealer I got it from) had put in a wimpy 700A 550CCA battery! Surprisingly we made it through last winter with no problems... Needless to say I replaced the battery today with a Costco 1000A 880CCA Kirland battery for $99. Good to go now
