bought a battery charger from harbor freight tonight. this is the one that i bought http://www.harborfreight.com/cpi/cta...emnumber=47447. hooked it up to the black bird to charge the battery. i noticed as its charging it goes from charging to full charge. bounces back and forth between both while charging.

i disconnected the charger. reconnected everything making sure that everything was connected properly. then it proceeds to bounce back and forth from charging at 100% to fully charged then back again to charging.

is this normal. i was expecting it to do a steady charge and then the green light coming on when the battery is fully charged.

thanks for any and all answers.
