You have to go pretty far back to get to a Mac with a removal battery—this would be the battery door accessible from the outside, like a ibook G4 or a polycarbonate black mac.
You can try again—
Try resetting the SMC https://support.apple.com/en-us/HT201295
Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
A lot of guess work here—if this happens to be the 2012 model MBP, you should always replace the SATA cable at the same time you upgrade the HD/SSD: https://eshop.macsales.com/item/Apple/8211480/ a known issue
If you have a bootclone try booting off that externally—this would be a definitive test in isolating the issue.

Are you saying no screen or anything lighting up? No sound?
Hard drive failed and replaced it with another larger one and everything is dead no signs of life at all
