I've got a rechargeable NI-CD 1100mAh battery. And It's standard charge would take 15hrs at 110mA. And also it's fast charge would take 4.5hrs at 330mA.
Would it be harmful for this battery IF, I would charge it at 500mA?
I know it would take less time than charging it with 330mA, But it's not the reason of my job here. I'm doing this because there is no charger with the specified Am that the battery needs!
Thanks...

The battery life will be reduced or in some cases cause irreversible changes if you charge at a current more than 10 % of the rated capacity. A constant current charger is recommended for Ni-Cd battery.

Do the math. You know you have a 15hr charge rate at 110ma and 4.5hr at 330ma. Compute the 500ma charge time and only charge it at that rate when the battery is run clear down. Do not use the 500ma supply to "trickle charge" the battery or you could do it some hurt. And... do not exceed the new computed charge rate!!!

Look up Panasonic's product line-up for Ni-Cd batteries. With a given physical size, some batts. can be charged very fast and others cannot. You need to know the specs. for your specific battery.
