Will the old battery (that you are replacing) charge up at all? If the old battery charges but the new battery will not, then it's likely a bad replacement battery.
To rule out the possibility of a corrupted battery meter inside of windows, you may wish to leave the laptop on battery power only, until it dies. A 5% charge will usually only grant you about 20 minutes of laptop life maximum. Since you left it charging all night, you should get a few hours of life before it dies. If you get a few hours of life, the battery meter software is corrupted.
Most likely though, the replacement battery is bad.
The battery is dead and it won't charge or hold its charge (all rechargeable batteries have a finite number of charge and discharge cycles). You need to buy a new battery, or just use the laptop connected to the mains supply.
