The battery died and I replaced it, and it died again. What is the expected voltage on battery when operating on external power? It is 13.6 V right now, with another new battery. Isn't this a bit low? It tells me the charge is 100%, yet the time left is only 6.7 minutes under 10% load. Confusing. Is something off here?
