Question
#1:
My
Digital Camera uses 1.5V "AA" batteries and your
NiMH "AA" batteries are 1.2V. Will they still work ? |
Answer
#1:
Yes,
you can safely use our NiMH batteries without any problems.
They can be used in place of your original batteries in almost
all digital cameras , film cameras, flash units as well as
most other electronic equipment. |

Question
#2:
I
am purchasing these nimh batteries for my Nikon Cool Pix 900
camera which I recently purchased. The camera manual states
that 1.5volt batteries are needed. In your testimonials, a
user of a Nikon Cool Pix 900 stated that the Nexcell NiMH
batteries work well. After reviewing the batteries, I have
noticed that they are marked as 1.2volt. Are these batteries
acceptable to be used in my camera and was the person in your
testimonial using these or a 1.5volt AA NiMH battery ?
If the batteries are acceptable, are they sent ready charged ? |
|
Answer
#2:
All NiMH ( Nickel
Metal Hydride ) batteries as well as all Nicad Batteries are
all 1.2 Volt for consumer use. Once charged they average 1.3
to 1.4V . So you can be assurred that these are the batteries
that everyone is using in their digital cameras and other
electronic equipment. We ship over 1000 of our Nexcell
NiMH batteries per week just for digital camera use and we
have found that around 30% of our customers have a Nikon
CP900. We also use one here ourselves for a lot of our product
pictures.
The NiMH batteries are always
shipped uncharged and must be fully charged before their first
use. |

Question
#3:
Does
temperature effect the charging of your NiMH batteries? |
Answer
#3:
Yes, but usually only if charged outside of the optimum
temperature range of 0°C to 45°C when Slow Charging
and +10°C to 45°C when Fast Charging. See the below for more
detail |

Typical
Battery Charging Performance of NiMH Battery Cylindrical Cells
Charge
Standard
Charging: Charging at
0.1C standard rate for 14-16 hours will greatly enhance the
NiMH battery's service life. Our NiMH batteries can withstand
overcharge at 0.1C rate indefinitely. Charging at or below
0.1C rate is suitable across a temperature range from 0oC
to +45oC.
Fast
Charging: All our NiMH
series can be fast charged at rates from 0.5C to 1C. Fast
charge termination measures should be employed. These include:
Temperature Cut-Off (TCO), Rate-of-temperature rise (dT/dt),
negative Delta V (-dV). A timer control set at 105% of nominal
capacity can be used as an additional protection. For maximum
capacity, a trickle charging can be applied after fast
charging. We recommend top-off trickle charging at 0.1C for 2
hours or 0.2C for 1 hour. Fast charging can be done at
temperatures from +10oC to +45oC. |

Question
#4:
What
is the average discharge curve of your NiMH batteries ? |
Answer
#4:
The chart below
shows the average discharge rate of our NiMH batteries.
Discharge rates can vary depending on the operating
temperature. |

| Question
#5: |
| What
are the number of charge / discharge cycles I can expect
from your NiMH batteries? |
| Answer
#5 : |
| Under
normal conditions you can expect any where from 300 - 1000
charge / discharge cycles from our NiMH batteries. Cycle
Life is dependent upon usage conditions and type of charger
used. |

Question
#6:
Do your NiMH
batteries lose any capacity during their useful life ? |
Answer
#6:
Yes they do
lose some capacity, but it is normally very, very gradual.
This is true with all rechargeable batteries, but some have a
very high rate loss. Our Nimh batteries are designed to
have a much longer cycle life than older generation Nimh
batteries. Normally after 300 - 400 cycles, capacity
will decrease 10 to15%. See the chart below. |

#7: |
| My
Minolta Dimage V digital camera requires 6+ vdc and the Nimh
batteries you offer supply only 4.8 on average. What effect
will that have on my camera? |
Answer
#7:
Be assured that his is not an issue at all.
Our Nexcell NiMH Batteries and our GP NiMH batteries can be
used in your Minolta Camera. We have many customers who
have the Minolta Dimage V and are getting excellent results
from our Nimh batteries.
Actually when charged the NiMH
"AA" cells have 1.3V to 1.4V per cell or 5.2 to 5.6V
from a set of 4 nimh batteries , and yet they will not only
out last Alkaline and Nicads, but in many instances they also
will give better performance. Our 1300 mAH Series are
specially designed for high current drain applications such as
Digital Cameras, Flash Units, etc.. |

Question
#8:
I noticed that the"
AA " nimh batteries you offer are 1300 mAH.
I also had heard that GP NiMH BATTERIES and other
manufactures have a 1500 mAH "AA" High
Capacity battery available. Will you have them available
some time soon ? |
Answer
#8:
We probably
will when they are available. Actually though the 1300 mAH
nimh batteries provide more bang for the buck for most
applications. Also you may want to read the note below.
This
information came directly from GP Batteries concerning 1500
mAH NiMH batteries.
At the present time 1500
mAH batteries are designed for medium to low current drain
applications. GP informed us that in order to
obtain 1500 mAH you loose some current capacity as a trade
off. This is true of most all 1500 mAH NiMH batteries, not
only GPs, since you can only do so much with "AA"
cells.
They stated that the 1300 mAH batteries are specifically
designed to handle High Current Drain applications and
devices -- i.e. Digital Cameras, Flash Units
, etc. -- and are the best choice for these
devices.
We also were informed by Nexcell that their 1300 mAH NiMH
Batteries are also designed this way ,and the 1300mAH nimh
batteries are specifically designed for extremely high current
applications.
Our Note:
Keep in mind that this does not mean that the 1500mAH NiMH
batteries will not do a good job powering equipment like
digital cameras, they just are not designed for high drain
applications, and will have a much shorter overall cycle life
when used in high drain equipment. |

Question
#9:
How well will your NiMH Batteries work
in Flash Units and Film Cameras? |
Answer
#9:
Our 1300 mAH
NiMH Batteries will all work very well in flash Units, and
film cameras as well. We have many customers who are
professional Photographers and are now using only our NiMH
Batteries in all their equipment in place of standard AA
batteries.

Question #10:
Are the NEXcell and GP batteries virtually the same
or is one better than the other?
|
Answer
#10:
Actually there
is very little difference from what we have found in all our
tests. We actually have found that the NEXcell batteries
do seem to perform a little better than GP batteries, but this
difference is so very slight. This is also true of the
TELEPOWER II batteries we will be offering when
available. We use NEXcell Batteries exclusively
in our Nikon CP900 and much of our other equipment we use on a
daily bases.
