YellowTop^TM Group 51 battery, making SPIRALCELL Technology® available for many of the most
popular sport import cars

October 24, 2007 (MILWAUKEE, Wis.) - For the last 12 years, OPTIMA Batteries® has been the power supply of choice for on-road and off-road racers and marine enthusiasts. Now, the sport
compact market can also take full advantage of OPTIMA's patented SPIRALCELL Technology®.
OPTIMA Batteries is re-introducing the Group 51 and 51R (2.7 liter/B24) YellowTop^TM battery,
designed to OPTIMA's high quality specifications and built to fit some of the most popular import
vehicles.

The re-launch of the battery will take place at the 2007 SEMA Show. The launch of the Group 51
YellowTop battery, has been greatly anticipated by a large contingency of import tuners, racers
and audiophiles since OPTIMA paused production in 2004, in an effort to perfect the performance
battery technology.

"The release of the Group 51 is important to our performance minded customers," said Steve Kepler, Executive Director for Global Sales and Marketing. "Its small package is capable of starting
high-performance engine, while delivering deep-cycling capabilities to audio enthusiasts and
extreme racers."

The Group 51 (2.7 liter) YellowTop battery features the following specifications:

Length:                9 15/16"
Width:                  5 1/16"
Height:                 8 15/16"
Weight:                26 lbs.
CCA:                     450
Reserve capacity: 55 minutes

The new Group 51 and 51R batteries complete an already extensive line of Optima batteries including the Group 35, Group 75/25, Group 34 and Group 31 YellowTop models. With the introduction of the 51, Optima can now fit many tuner cars including the Subaru WRX and
Mitsubishi EVO as well as domestic sport compacts and import SUVs with a dual purpose
YellowTop battery. The Group 51 is also able to fit some of the most popular European vehicles
from Audi, Volkswagen, BMW and some Mercedes models. This new battery is the most compact
and lightest of the entire family of OPTIMA Batteries, which includes not only the YellowTop dualpurpose automotive battery, but also the RedTop^TM automotive starting batteries and the BlueTop^TM deep-cycle and starting marine batteries.

The patented SPIRALCELL Technology in an OPTIMA Battery is what differentiates it from the
competition and is apparent in the product's appearance, featuring a six-pack design, which holds
the six compressed spiral-wound cells.

The proprietary technology provides the following advantages to traditional lead acid batteries:
• Optimal starting power, regardless of temperature
• Up to 16 times the vibration resistance
• Up to twice the cycle life
• Lower self-discharge (longer shelf/storage life)
• Completely leak-proof, spill-proof, mountable in almost any position
• Maintenance free
• Faster recharging capabilities

In addition to these benefits, the battery's completely sealed case makes it the only battery in the
world approved for air transport by both the United States Department of Transportation (US DOT)
and the International Air Transport Association (IATA). Most batteries can be shipped via ground
transport only.

The new Group 51 and 51R YellowTop batteries are now available through leading battery
distributors throughout the globe. Consumers should look for the unique colored top and six-pack
design that OPTIMA is known for throughout the world. For the nearest retailer, consumers can
