Blue Tooth Speaker (BTS09) will not take a charge
My BTS09 will not take a charge. When I plug the cable in the red light comes on for about 2 seconds then goes off. If I leave the cable plugged in the speaker doesn't charge. I've tried multiple cables and multiple plugs. When the speaker is turned on and connected to a device, it shuts down in a minute or so. On my phone it shows a 50% charge that drops to 0% when trying to use the speaker. Anyone have any suggestions or is the battery gone? The speaker is about 3.5 to 4 years old.
