Dead battery? Please see recorded multimeter voltages.

[minieggroll]

Hello,

My GZ250 will attempt to start but will not unless I either jump start it or push start it. I took some voltage readings for your reference to help see what the issue may be.

With the bike off: 12.5v
With the bike on: 12v
When I push the ignition: Drops down to 6-8v and stays around there while the ignition is held

I've read online that the battery is dead if it drops below 9.5v when the ignition is pressed. Is this correct? I checked the voltage while jumping the bike and it never dropped below 10.5v while I hit the ignition and successfully started the bike.

Thanks in advance for your help!!!!
