I recently picked up a few of the CF series batteries, and all of them have worked great except for one. It worked fine for a while, and then suddenly... nothing.
Clicking the button: No lights, no voltage
Clicking 5 times quickly: No lights
Attempting to charge: The charger's light stays solid green while battery's button quickly blinks a very faint orange. The quick, faint orange blinking is continuous for as long as the battery is connected to the charger, it does NOT blink 15 times and then stop or anything like that.
I've made sure the contacts and threads are all clean. All of the batteries have been used with either a Mini Nautilus or K1 and charged on the Aspire charger, and this is the only one I've had any trouble with. Any ideas?
