I got to take some of the blame as it happens to me a lot on forums. I write big long confusing posts and some people dont absorb it correctly. It seems like time2roll followed along just fine. While others are yelling at me saying 12.64v is not fully charged. I was hoping we all agreed im closer to 90% charge from the 5a battery tender and the main question of the thread is should a 4a load make the batteries drop to 12.4v?
you are not at 90% charge
if your initial 20ampHrs use was with a high draw inverter for a large load, it was actually more than 20 ampHrs due to the chemical reactions called perkurt effect
i was 88% counted with a ampHr/watt meter
puling 50% more load aka 6amps, and batteries were maintaining 12.63v
NO your batteries should not drop to 12.4v with a 4amp load
