AT&T will replace 17,000 backup batteries for its U-Verse TV system after a handful of small explosions and fires, reports the Wall Street Journal. The batteries, made by a now-defunct Québec company, were housed in outside equipment cabinets. There was property damage in two cases but no one was hurt by the mishaps, which AT&T says won’t affect the Internet-based TV service.
AT&T began investigating the batteries after an incident in October 2006, but an outside evaluation reported no higher risk than comparable batteries. "However, these batteries no longer meet performance requirements," said a company spokesman, and will be replaced at a cost estimated at a few million dollars. U-Verse has about 126,000 subscribers and AT&T hopes to reach 1 million in 2008.
