I mentioned this in a old post somewhere but the reciepts and memory were gone and did not respond to the where it was questions. As its tax time walla-found the stuff. The place was TNR Technical. The have offices on both coasts-Florida and so -cal.
I sent them my Ikelite 200 ni-cad and they rebiult one for$ 42.76 plus frieght of 7$. Way cheaper than new unit.
I found them from a friend who sent other ni-cad work in for way cheaper than new replacements.
On the Ike 200 module(7.2v-3.0ah rebuild) you can not tell any differance to the unit other than new cells inside.
I recommend them highly. The web address is http://www.batterystore.com/
I just called and mailed in the stuff-quik turnaround as well. Hope this helps Mark
