That's not "new" battery. Yes, dead battery not able to hold charge from charger, it's kaput! Auto-charger most likely too powerful for motorcycle battery as well, only need amperage = to 1/10th capacity and 8-10hrs charging time. You can't force it faster, that will destroy battery that might be saved as well.
Jump-start pack may work, but again, it needs to be tested and confimed good. Such as starting car all on its own. If you can't get bike and car near each other to jump-start, remove battery from car and bring it to bike
Once we confirm your bike-batteries are dead, you can toss them and get new one. There's no way around this.
