Battery Voltage

[Okiegent]

I have a 12 volt battery that when I put it on the charger at normal reconditioned at 0,3 amp charge.It goes through the steps all the way to storage mode. It is a IP65 12/15 charger. When I first unplug it registers 12. 4 volts with the multimeter. Then immediately starts dropping off to 11.67 volts. This battery was discharged to 11.56 volts before I put it on the charger at the normal reconditioned mode. I hooked it back up and selected normal mode and will let it go through that and check again. Can anyone give me your thinking on the condition of the battery?

A battery that won't hold a charge is defective and will need to be replaced.

If there is no load on the battery and the voltage is dropping as you indicated, it is time for a new battery(s). You can always pull the battery and take it to a shop and have them test it.

Junk.
Replace it, and keep the new one fully charged. Always.

How old is the battery!! They all die after several years. Time to replace.

Thanks folks for your thinking on this issue. I believe I can agree. It probably has a bad cell I am thinking. The battery is 6 months old and is a interstate battery . I have had good luck with them in my boats and other equipment. No issues keeping them charged as they are on a constant battery minders and chargers. First one I have had issues with in years. This why it surprised me.
