I bought four 12Ah batteries from Home Depot, and while I've had no issues with them so far, one of them isn't charging correctly on my wall charger. The battery shows only one bar and when I plug it in, it quickly indicates that it's charged with a solid light. However, when I tried using a 65W PD charger (DCB094K) plugged into the wall, it seems to charge fine, but I can't tell if it's fully charging yet. I'm worried that I may have discharged it too low. Could anyone shed some light on what's going on?

It sounds like your battery might have a deeper issue if all chargers indicate it's full, but it’s still at one bar. Using a voltmeter is a great next step. That’ll help you determine if the battery itself is the culprit.
Try using a different charger if you haven't already. If it still doesn’t charge, I recommend reaching out to DeWalt's customer service. They're pretty good about fixing issues quickly!
You might want to check the amperage of your wall charger. A couple of mine are 2A and 1.5A, and they struggle to charge larger batteries efficiently. You can usually find the specs on the back of the charger. If it’s not putting out enough current, that could be your issue!
Thanks for the tip! I'll check the amperage on my chargers to see if that's the issue.
Small chargers can work with big batteries; they just take longer. Another thing could be that the battery isn’t seated properly. Make sure you push it down firmly into the charger.
I’ve already tried three different wall chargers and a PD charger, but no luck. I think I’ll use a voltmeter to check if the battery indicator is faulty.
