Sunn Battery sells aftermarket (Kendoo) FNB-41 packs for about 30 dollars. They also sell on eBay for cheaper. See: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=296&item=1949838184 Their Icom BP7 and BP8 packs are also VERY reasonable. Here is their web page for radio batteries: http://www.sunnbattery.com/category.html?UCIDs=832645 Individual and bulk batteries are very cheap from them, too. N2ERN
