Ok and thank you for your reply.
The battery only took about 15 mins to charge to 13.8v but I'll take your advice and take the charger with me tomorrow. The car is 50 yds from daughter's house. I'll take it inside n charge it. I got soaked working out in the street today.
Would a new battery be an option if this one is failing? I could take it n get it tested for faulty cell.
