I would never buy a battery pack w/o being able to "test the fit" first. Over the years I have purchased batteries from Yost/Batteries America in person for my Icom W-32, & have been very pleased with the fit & length of service. [almost 10 years] However, a year ago I needed a battery for a Yaesu FT-50. I went to their booth with the radio, & their battery could barely fit on the radio. I tried 3 different batteries, & none of them would fit w/o much effort. It seems the vendor in China did a poor job of checking the fit on that battery, while the vendor did an excellent job of checking the fit on the W-32 battery. I ended up finding a proper fitting battery from Pro Star who also sells Chinese batteries. The quality between fit, & length of service varies widely between off shore suppliers. I'd take this into consideration before sending money to China. At the worst, buy these Chinese batteries from a US vendor, using a credit card so you can return them should they not fit.
