Battery Trouble
 

The cold might have gotten me. I am having issues keeping the battery charged in my 2010 LR4 5.0 If I start it and don't drive for at least 10 minutes, it won't have enough juice to restart. I have even recently taken it on some longer drives (1hr +) and still run into the problem. Several times I have hooked it up to my battery charger and it charges the battery to "full", but I come right back to the same issues in a week. Is this just a case of get a new battery? The sticker on the battery says 2017, I also have no issues while driving or any other warning messages. Is there something I am missing?
