I have had the Scala Q2 system for about 2 years. Until recently, it worked very well, however, now the battery appears to be dying. A charge only lasts about 1 hour. It's not on warranty anymore so I can't send it back. I phoned Cardo and a guy on the phone told me that they were not set up to replace batteries and they would not sell me new batteries, because they're soldered in and the customer cannot open the unit. I'm pretty good with electronics, so I opened it anyway. It contains a 3.7volt lithium polymer battery with wires that are soldered in. The dimensions are 4.5mm x 21mm x 48mm. I have searched the internet, but have been unable to find a suitable replacement battery so far. Has anyone here solved this problem?
