I'm ready to purchase my optima battery and have printed out the specs on the rear mounted battery install from the website.

The directions state to use SC34A as a part number.

Optima website does not list this part number or the National Stock number listed below the specs on the page on the website.

I did some research and by process of elimination I found this current model number to be the closest.

Optima 34 red top Battery -

Optima 34 RedTop Battery Voltage: 12v Minimum Weight: 37.9 lbs. Cold Cranking Amps: 32°F 1000, 0°F 800 Length X Width X Height: 10.00" X 6.86" X 7.81" Capacity Ampere Hours @ 20 Hr Rate: 50 Reserve Capacity: 110 Internal Resistance (ohms): .0030 Post Type: SAE Post Warranty Invertermation: 36 months free replacement, remaining 36 months prorated

Being a ex-Sears Automotive employee while putting myself through college I am fairly certain the group number is the most import, which in this case is 34.

I also check the LXHXW and it seems very close to the spec on the ERA site.

Any advice on this.
