i have found group 31 batteries for a little over 100.00 each and they are 12 volt is this a good price for these and they will be going in a 2005 winnabago vectra with a 8.9isl engine
they are for the chassie and i dont know the name of the battery what is a good brand to use the reason iam getting them is when i check i have 11.9 or 11.5 and when i start it goes to 14.1 and after i shut down it drop back to 11 something
