Since this forum is over-saturated with walmart battery topics, I figured I'd throw this question in here....
I've been using this 9v a couple times and it works great. The other day I recharged it until the red/green light was blinking and I then plugged the ua5 in to see if it turned on. Everything worked fine but now the battery status lights wont turn on when I hit the black button. But when I plug it in, the light flashes to show it's fully charged. I have other batteries but was just curious, should I ignore the lights and use the battery as usual? assuming ~5 hrs?
