battery replacement

[dvl57]

when you're replacing the battery, is there anything you need to know in regards to having the stereo or nav "lock out"?

in my previous vehicle (Land Rover), when you replace the battery, you get your head unit locked out...you need to enter in a PIN #.


I'm wondering because....in my 08 H2, the battery meter on the dash fluctuates ...in the morning when it starts up...it's strong...during the day (after driving it), the meter is lower....(not to the point where it's extremely low), lower than in the morning.


I was wondering what other owners' thoughts were in regards to this.

thanks.


will a blue optima top fit w/o any modification?

I had terrific success w/ the blue optima D31M on my Land Rover..
In addition, I heard some failures from others in regards to the Optima Yellow tops.


Cheers.
