I bought two of the 6 volt golf cart batteries from sams club. 225 amp hour.
I thought I checked the voltage when I brought them home a month ago. and it seemed normal.
I just installed them into the coach, along with my linklite battery moniter/shunt.
I was shocked to see, that the battery monitor was showing 16.6 volts.
I checked the batteries, and each one is giving out 8.3 volts. so when I put them in series, I am truely getting 16.6 volts.
It is pretty cold out. 0 to 20 degrees the last couple days.
is this normal for the new batteries? seem pretty high.
what voltages would I normally see.
The batteries have not been hooked to a charger.
just going to let them sit there for a while. and keep an eye on that.

I would first doubt the the monitor and check with a volt meter.
If they are high - they will drop as soon as you use them and only charge back up to as high as the charging voltage given to them. In other words - you can't charge a battery up to 16 volts with a 14 volt source.

Jon,
Something is radically wrong here....
Do the batteries have three caps or four??
Have you checked them with a reliable stand alone meter??
A 6V battery at 8 volts will be hotter than .... and boiling acid out of the vents.
You say they have not even been hooked to a charger.
If there really is no charge power and you are seeing this sort of voltage, then there is something going on that you don't know about.

The last time I was at Sam's, they had both 6 VDC and 8 VDC batteries on
display. I'll bet you got the 8 VDC version. 3-cell batteries cannot put
out the voltages you're reporting.

Thanks. Yep. Wrong one's.
no where on it says anything about 8 volt. except the 8 on the part number.
Should of grabbed them off the shelf myself!
