I am using the standard charger for the moment. I took apart the controller and looked at the charging circuit, it is really simple and the 2.4V cell can becharged with it, but more time is required (I did about 3 minutes).
The standard cell is only 50mAH and my 2.4V is 80mAH, assuming that the current drain is similar under 2.4V operation (this will depend on the car electronics), we should expect longer run times.
I dont think the standard charger is at all good for the battery and it wont do long term at all, to charge these things properly, you need a constant current source circuit. The design can be found on the web, I am going to build a stand alone charger around this.
When I am done, I will be sure to post the results !
