Default New up date, on battery maintainer!!

OK, Took it off the EXT. cord and it took about 2 hrs, for the charger to show me a green light.

And took it off the charger and then checked it again, Now with not useing the EXT. cord. it now shows me on my gauge 12.73 Volts.

I will keep checking it now and then..but i sure hope its fixed now that i have it just going to the wall, with out any EXT. cord.

but man if i just open the car door for a sec, or open the hood and any of the little lights go on..even for a min. it seems to take this new charger back to the charge mode for about 1/2 hr to get it to show green full charge again.Man thats slow.

So what are your thoughts on this matter?..does it sound about right? Thanks, dbiddle.

A 12-volt battery will measure at about 12.9 volts when it’s fully charged and about 11.4 volts when it is fully discharged.

I have an Optima yellow top and I use a CTEK charger with it. I just wanted to let you know that I see the same thing - if I open the door for a few seconds and all the interior lights go on, the CTEK red light goes on and it takes a good while for it to go back to the red. It's been doing this forever and I never have a problem starting the car.
