Hi and Welcome to the Community!
Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain connected to a known-good wall charger (not PC USB):
This has been known to "kick start" some BBs.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
The results of this will indicate if it's your BB or your battery that has the problem. Note carefully that "new" and "known good" are not necessarily the same...while rare, a new battery can certainly be defective. Further, only by finding someone else with an identical BB with no issues can you actually trade batteries and narrow down if the problem is the battery or your BB.
Good luck and let us know!
