The CTA 325 mAh battery I had been using in my Mini³ would no longer hold a charge, and is apparently no longer available.

I found this POWEREX MHR84V 300 mAh replacement from Newegg is reasonably priced, fits well, and seems to have far greater capacity than the CTA ever had (despite the slightly lower mAh rating)...

The Mini³ parts list page says, "The Maha PowerEx 8.4V 300mAH or Maha PowerEx 9.6V 230mAH batteries are also favorites, but they are oversized and is a very tight fit."; however I find it fits about the same as the CTA did.

I too installed a Powerex MH-84V300 battery in my Mini³ with out too much difficulty.
