"here's an equation to use:
Your battery's Mah x 1.5 then divide by charger output.
so for you... 1400 x 1.5= 2100
Divide that by 300 (your charger's output) and you get 7 hours."
Just do 6:45 hours because 1200mAH/250mA is 4.8 so 4.8 multiplied by either 1.4 or 1.5 (1.4 for Ni-CD). that gives you 6.71 and 71 is just about 3/4 of 100 so you get 6 hours and 45mins
