I'm not saying buy Walmart's battery or Canadian Tires batteries. I'm just trying to give an example
UPDATE...
I finally installed a new 121r battery as the original one was sulfating bad and I got to say it is a tight fit. I had to stretch the positive cable over and on top post and to push the air tube in to be bolted on. The 96R was shorter but wider, and you would only be losing $10 and 10 CCA VS the 121R.
If you think a group 35 would fit, well it doesn't as it it too high.
But If I had to do it again which I will, I'm going for the 96R
To be specific the Energizer 96R AGM Battery
