Ok, I went to pull the battery out of the pup to throw it on the charger when I realized I never disconnected it after our Fathers Day trip. I am normally pretty good at making sure I disconnect the battery before putting the pup back in the garage. But I totally forgot to disconnect it this time!!!! So, I hooked it up to the charger and it was at 4% (holy crap!!) after about 30 minutes it is now up to 63% and not moving from there. Is this thing toast or will it just take a long time to charge back to 100%????
