FOR IMMEDIATE RELEASE

Bellingham, Wash., May 28, 2004 - Power system provider Alpha Technologies, enhances AlphaCell™ battery family with the introduction of the new AlphaCell 430Li battery.

Based on Lithium-ion technology, the 430Li has been designed specifically for Broadband communication networks and will debut at this year’s Cable-Tec Expo June 16-18, in Orlando, Florida.

The 430Li’s superior power density allows for one 36V 160Ah battery module to replace up to three 36V strings of traditional valve regulated lead acid (VRLA) packs. Possessing twice the life of VRLA technology, the 430Li offers two to three times the runtime for an existing VRLA battery enclosure installation. Additional features include; zero gas emissions, built-in solid-state battery management and reduced sensitivity to temperature.

“The AlphaCell 430Li is a perfect compliment to our existing line of AlphaCell batteries, providing extended runtime options for applications where expanding or upgrading existing installations is not an option,” commented Paul Humphreys, Alpha Technologies VP of Marketing, adding, “The AlphaCell 430Li provides an option of increasing runtime for subscribers without the need to add a battery expansion module or replace an existing enclosure.”

These batteries are ¼ the weight for the same energy stored in VRLA products - translating into shipping cost reductions, and easier installation.
