Ni-cd 7.2 volt R/C charger doesn't fit batt!!

Can a domestic 7.2 volt Ni-cd charger for remote control models be adapted to fit a foreign made battery pack?? (The pack is also 7.2 volts) The wire lead clip with round and square hole on the end is only about 2/3 size of the one on the charger. Also will this pack even accept a charge from the chargers sold in stores? I think the pack was made with the toy by Echo Toys of Hong Kong. Thanks!

Maybe it would help if you posted a picture of the two connectors ?

.. and does the battery charger have a "mA" rating ?

.. and what size is the battery pack ?

.. is it even a Ni-cd ?

Is the connector whitish tranparentish plastic? THat sounds like a Tamiya connector. If they both look the same except one is smaller, one is a regular Tamiya connector and the other is a mini Tamiya connector. JUst go to a local RC hobby store and get the two connectors and make your own conversion wire.
