There was a TSB for a parasitic battery drain from the network gateway ECU for some of the 2013 models. See if that's an issue otherwise, even if you get a replacement battery, that slow drain will kill your new battery also.

Two factors in favor of the Bosch over the Lexus,
1.) longer free replacement (no pro rating) of 4 yrs vs 2 yrs, and
2.) lower price ($112, after a $30 rebate).
Also, it seems that AGM is superior to traditional lead/acid design.
FYI: Install was pretty straightforward, except for opening the cable "brackets" on the inboard side of the battery "case" (insulator?), it's incredibly tight under there.
