I have a 2002 Outback H6.
The original battery was replaced by Subaru in 2009.
The existing Subaru brand battery has top terminals and measures approx:
L8.75 x W6.75 x H7.75.
The owners manual, page 12-4, states "Battery type and capacity...75D23L"

I found a reference from the Battery standards people that says a 75 should be L 9 1/16" x W 7 1/16" x H 7 11/16"

Type 75 batteries seem, also, to have side mounted terminals.

The Walmart web site shows the EverStart MAXX-75N with the side mounted terminals.

My concern is whether the cables in the car would fit, and whether the terminals should be mounted at the front of the car (bumpers side) or the rear of the car (firewall side).

Anyone have any experience with this?

The 75D is a reversed terminal battery case series. You can also use a 24F or 35 Series. The main thing you want to look at is the CCA rating. The higher the better, especially with all the electronics in the car.

Look for a group 34R or group 35 battery. They are generic sizes which are widely available and close to the stock Subaru battery.
