If you want to stick to lead, highly recommend
Odyssey PC-2150 G-31's
for such a stressful use case.
Much higher current discharge rate, excellent longevity (for lead) while deep cycling if cared for properly.

markz said:I literally just read up on this. The Odyssey battery is a great alternative to the Optima batteries. I did read that Sears has a similar product, but since Sears is gone in Canada I did not read the 2009 post in Pirate4x4 forum. I noted the Optima batteries are $240cdn (www.4wheelparts.ca, Costco requires account # to view prices), and Odyssey was $150cdn (same 4wp.ca website), and I remember reading that Optima batteries from Costco arent the same as the regular ones sold.
