Which OPTIMA battery to use?

[mountainbiker]

The Optima fit guide online doesn't list the HUMMERs. If you have any experience with them in your H3, maybe you can answer these questions:

• Do you know which model/part number you used? (Was it the 34 series red top?)
• How did it fit (e.g., taller, wider, etc.)?
• How did you secure it (e.g., gravity, strap or other)?
• Any pictures of it sitting pretty in your engine compartment?
