I've had my new/refurbished battery for about 2 months now and the CAC has been sitting at 154.61 steadily. I'm upset as I thought it should climb to about 160? I haven't range mode charged it yet which might help? The problem is for me to range mode charge, when I reach my destination I can only give it a trickle charge at 15A for about 8 -10 hours. Any ideas?
