Ok.....C/10 and C/2 are confusing me....but I've now taken my brand new 7.2v 1800mah batt.....and hooked it up the 9v 200mA charger that I found. This is it's first charge.... I've watched the current flow for over 30-45 minutes...and it has read about 245-250mA. With this information, would it be correct to believe that I would charge this batt(watching it closely, of course) at this equation.....1800/250=7.2 hours....give or take a few minutes?!!??!! I also assume that 1.45 is max volts for each cell in your 6*1.45=8.7v equation.....correct?!!??! Is the C/10 meaning, for example..1800/10=180mA??!?!! And the C/2 meaning, for example..1800/2=900mA?!!! Thanks for your help, man. Laters
