Thanks for the comments!  I am thinking from what little I have read so far, that due to the venting and other accommodations for the hybrid battery interaction, that the Panasonic is a better fit for this hybrid application.  I need to do more research for sure.

I've been buying ours at Costco for years. Their Interstate batteries are very good. By the way, if you are not going to drive your car for a month, I recommend keeping the battery charged with a battery tender.

Thanks.  I definately will use a tender in the future.

Newbie here.  I could not find this topic back to 2012 but am sure it's been discussed.  The 12V Panasonic battery may need replacement.  (Is not staying charged when car is stored for a month).  I would like to replace it with the OEM battery but not pay the dealer the $600 when I think they run around $400.  However, I have not yet located a seller in the USA.  I prefer to stay with the Panasonic brand battery.  Thanks for any suggestions on who may carry them.  

Thanks,
