Hi, Amy. I have the following question about this ECHO kit - I ordered one for my mom (from HealthCabin) and it was absolutely ok...until the battery discharged. Now she can't charge it with the USB-charging device included in the kit. It seems that everything is working, all LEDs are properly lighting, we measured voltage of the charger - it's 4.2 V as promised. However the battery isn't actually charged although we gave it enought time (the whole night). This happens with both batteries in the kit which probably means that it's not about the batteries. Maybe the charger device is defective? Or can this problem be fixed by pulling central contact of the battery a little bit up? I will appreciate your asap. reply. Thanks in advance.
