Yesterday, I had a battery in a wall-charger that never changed from "red". Thinking maybe my charger went bad, I put it on my USB charger connected to my computer.....same thing....hours later, still "red". I am now using the battery, and it seems to be fully charged...it is working fine, even though the light never chaged from red. So, what can cause this? Do you think the problem is with the battery? If so, are there any suggestions regarding what can be done to fix it? Thank you in advance for any suggestions.
