alright. I have an odyssey pc680 battery that I ahve killed on a few occasions.
Now to the issue. The resting voltage is usually less then 11.7 and when I hit the start button it drops quick until the car fires up. While driving it will normally stay around 13.9-14.2 volts but sometimes when I am not on the gas, or when I am ata stop the voltage will drop down to 12.5 volts or so. If the battery sits for more then 2 days without being started it will need to be jumped. I am pretty much just trying to get a second opinion as to if the battery is shot or the alternator is going. I am thinking its the battery.
P.S. it is relocated to the trunk and is powering the car off of 4ga.

 

I am no expert but sounds like the battery is shot. You can take the car to autozone and they have a machine they can role out to your car to test the battery and alternator.

 

Sounds like a shot battery to me. Pretty typical for lightweight batteries.

 

yea thats what I thought. I am gonna go up to the 925
