I think this is the Walmart deep cycle battery I tried recently.  It was
$40 and 90 Ah, iirc.  I took it back after a week because it was too tall
to fit under the driver's seat.  I don't have  a swivel on the driver's
side, and the tall battery prevented the seat from sliding back to where I
want it.  I usually keep the seat nearly all the way back despite being
only about 5'7" tall.  With the battery installed, the seat was forward
enough that  the angle of my ankle felt less than 90 degrees, and got
uncomfortable even on a 2 hours drive.  I also like the seat farther back
so I am that little bit farther back from the impact in a front end crash.

I traded the battery for the group 41 regular battery.  Fits nicely in the
battery compartment, but is not deep cycle and surely will not work as well
electrically.
