I've got an issue with my DeWalt 6Ah battery that won't charge. After using my drill, the battery died. I swapped it out for a different one and put the dead battery on the charger, but it doesn't show any lights or indications of charging. I have both a fast charger and a dual battery charger, yet it won't work on either. I even tried the reset trick by jumping the B+ and B- terminals to a good battery, but that didn't help. Is there anything else I can do to troubleshoot this?

Is your battery a Flexvolt? Those high-amperage batteries can be tricky since they run in different voltages depending on where you use them. A lot of people report breakdowns with these batteries. I’ve had issues with several of mine, but I managed to fix a couple by checking the fuses and solder connections. Might wanna explore that route as well!
If you've already attempted the reset, I think your best bet might be to file a warranty claim if it's still within the period. But if you're out of warranty, there are some online services that specialize in battery rebuilding. It's worth looking into!

No, it's not a Flexvolt battery. Just a regular one.
