A:The primary problem with rechargeable nickel cadmium (NiCAD) batteries is their longevity. When used in a personal CD player, some rechargeable NiCDs last barely as long as a single disc.

How much longer? A set of these Ni-MH AAs used in a personal CD player ran for about 7 hours; two AA Eveready Nicads in the same player ran for about 4 hours  In a personal cassette player, the Ni-MH ran for nearly 11 hours, as compared to barely seven hours on a pair of the Everyready Nicads.

The other advantage of Ni-MH batteries is that they are environmentally friendly, unlike cadmium. Also, they don't have the "memory" problems of Nicads, which mean they can be fully recharged without being completely discharged.

Q: How do the Nickel Metal Hydride batteries last in other equipment?

A: We performed several tests ourselves in order to test how long the NiMH batteries lasted in Two top brand  metal detectors and two different Digital cameras.  

How long did they last?  Basically our NiMH 1300 mAH "AA" batteries lasted almost twice as long as standard Nicad rechargeable batteries in both the Metal Detector and the Digital camera tests, and at a fraction of the cost.   The metal detectors seemed to be even more responsive when using the NiMH batteries.  We performed a depth test in a sand box and the NiMH batteries consistently averaged an extra one inch in depth on a "Copper Clad Dime" and just a little deeper on a "Silver Dime".  Needless to say were impressed.  What detectors did we use you ask?   One was a Garrett Ultra GTA 1000, and the other was a Fischer 1260X.

We used a Epson Photo PC650 and a Kodak 210 Digital Camera in our Camera tests.   Again, our NiMH 1300 mAH "AA" batteries  lasted over twice as long as standard Nicad and much longer than standard alkaline batteries. So if you have a digitla camera that uses "AA" or "AAA' batteries NiMH is the most economical way to power them to date.

Also we have Mr. Tian-HUAT OH in Singapore who has acheived 194 shots ( 32 with Flash ) from his Nikon CP900 Digital Camera using our Nexcell Batteries with the C-777 charger.   As a reference - OH - could only achieve 10 - 15 shots using standard Alkaline Batteries.  Check out  OH's Battery Page.
