How to change the internal battery of a Monarch Pathfinder 6039 scanner. Specs say it has a 3.6 internal lithium ion battery. It will not hold a charge and I would like to change it myself rather then return it to just have a battery changed. Previous model the 6037 had a backup nbattery in the handle along with the main battery but I am unable to locate the battery in the 6039 model
