The European offices of Columbia Sportswear are recalling rechargeable battery packs that have been delivered to retailers to heat some of the jackets in Columbia's OmniHeat line. While the jackets themselves are safe, it is possible that the batteries may lead to overheating the jackets, which could result in burn injuries or fire. The technical problem is limited to packs with the serial number 054978-001, which are being exclusively sold through Columbia's corporate stores or its factory outlets in Salzburg, Austria; Troyes, France; Ingolstadt, Munich, Frankfurt and Zweibrücken, Germany; Las Rozas, Spain; and Portsmouth, Cheshire Oaks and Kensington in the U.K. It only applies to products sold between June 14 and Nov. 22. There is an explanation for the odd fact that the recall only affects these stores and factory outlets: Antti Kärävä, marketing director of Columbia Europe, points out that there the company had already announced a global recall for the packs sold for the autumn/winter 2011-12 season. Apparently, a small quantity of leftovers made it to some of this winter's jackets, which were only shipped to these stores.
