Hi folks, 

        As my Start battery is 10 years old I”m considering a prevention purchase of a new battery. 

Below is text from a battery email from another list with some thoughts. 

Is there a 91 group that fits?  And why would someone use something other than a group 41? 

What battery would you recommend as a start battery these days? 

Have their been any improvements we can take advantage of?

Or, do I go to Walmart and see if I can find any group 41 on the shelf.
Old email below:

Group 91 and 40R are good fitment. FWIW, there are only a couple manufacturers of std lead acid batteries and almost any name brand you choose is going to be about the same. Napa doesn't make their own, Interested etc are going to be all about the same other than warranties - but read the fine print as that varies. 
Autozone has the 41DL: https://www.autozone.com/batteries-starting-and-charging/battery/p/duralast-battery-41-dl-group-size-41-650-cca/31694_0_0
I'm using the Odyssey Battery 96R-600 in my Westy.

I've been using interstate batteries on my vans for 23 years with good results.
