My Yaesu HT needed a new battery and I bought one from Batteries America. They advertise in the QST magazine. Their ad in the magazine shows your HT rig and the battery required. Contact info is: www.batteriesamerica.com
or 800-308-4805 or email firstname.lastname@example.org
I was pleased with their service, delivery, price, and knowledge of the products they sell.
Hope this helps.
