The OEM Panasonic battery that my 4Runner came with lasted far longer than anything else I have used, but I think I recall that they do not meet U.S. environmental regulations so they cannot be purchased separately?
I'm sure the dealer has a substitute, why not just buy that? I've been running OEM Toyota batteries for quite some time and never got less than 4 years from one even through brutal winters and having the truck sit for months at a time without use.
