Battery location & heater core

[dbebb55]

Hi guys...Unbelivable, I can't find the battery on my 1994 540i. I have to assume it located under the rear seat which I can't seem to remove.
Also, I have to replace the heater core. How big a nightmare is that project??
I'm going out to the shop to work on my Lotus....Soooo much easier.
Thanks for the help
Dave
