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 are the number of charge /
discharge cycles I can expect from your NiMH batteries?
Answer #4: 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.
