Digital Camera Battery Use an Add-On NiMH Power Pack SUMMARY: Get more use out of your old AA NiMH batteries.   If your digital camera only supports proprietary batteries, see if it also supports an add-on power pack that uses AA NiMH batteries. If you have many extra AA NiMH batteries from previous digital cameras or other digital technology purchases, a battery pack may be a wise investment. Though a power pack may add a little weight to the camera and cost more than a couple of proprietary batteries, it may save money in the long run if you have plenty of NiMH's that would otherwise no longer be useful in your new digital camera.   Add: Del.icio.us | Digg | Furl | My Yahoo!   Discuss This Tip Print This Tip Get E-Mail When New Tips are Online Return to the Digital Camera Battery page.
