Hehehe i mean my batteries when charging will indicate orange light at first (light indicator in the charger) then in afew minutes they will blink simultaneously. When in use, my imac will still indicate that my batteries are at a very low level. Just this afternoon they would automatically be lost in connection. Almost 3 years ko na sila gamit. I guess the reason why they got drained is maybe because i overcharged them and i just keep them in the charger while plugged and never took it out when not in use. And most of the times, i keep my imac keyboard and mouse on when i leave the house.
