Battery Pack BP-R1EU for Teac radio R1

Teac apparently provides no original Teac battery packs more a product of the secondary source was therefore supplied. After only three charging cycles a cell had been broken, so that the total voltage is no longer reached 7.2 V and the radio had to run to the charger permanently again. It has been necessary several phone calls and emails with the supplier until I finally received a replacement of the defective battery pack after about 2.5 months (from the same supplier). Allegedly, he had already sent a replacement battery at least once, but never arrived. This is not a reliable source of supply for Amazon!
