1.     How to choose Lasting Power or High electric current output?

When manufacturing high capacity Ni-MH cells, it is very difficult to have both “lasting power” and “high current output” at the same time due to the physical properties of the Ni-MH cells.  For example, the rechargeable electric screwdriver, due to its high energy demand, it usually comes with three high voltage AA cells, but they run out of energy quickly and recharging is necessary at short intervals.  On the other hand, the walkie-talkie uses little energy; therefore, it usually comes with three longer lasting AA cells, so that users can use them for an extended period between charging.  If we exchange the batteries in these two devices, then the high-energy demand of the screwdriver will damage the cells designed for the walkie-talkie and vice versa.  Therefore, the best solution is to design a cell for a specific usage, either “Long Lasting” or “High Voltage Output.”

2.    What is the best type of rechargeable battery for digital cameras?

We all have the unpleasant experience of an electric device damaged by a leaky battery.  When it comes to choosing the best rechargeable batteries for the digital cameras, the first thing to consider is safety and secondly, we all want the highest capacity so that we can shoot more pictures between recharging.  The iPowerUS 2100mAh Ni-MH rechargeable battery fills the bill perfectly.  Other than the highest rated power capacity, it also added many safety features such as safety vent, safety insulator, shock protection, temperature protection and low corrosion electrolyte plus a safety fuse to prevent any leakage or explosion.  These safety features will not only protect the users but also the digital cameras. 

3.     Will I win remote-controlled car races using the iPowerUS 2100mAh digital camera batteries?

Don’t hold your breath.  Even though the iPowerUS 2100mAh has a very high capacity and voltage, but it is not designed for instant high-energy demand such as a remote-controlled racecar.  To let you in on a little secret: to win the race, use the cheap low capacity but high instant output Ni-CD rechargeable batteries, you will out run all the Ni-MH cars. 

4.     Why some of the so-called “high capacity” cells perform poorly in many of the high tech electronic products?

As the digital cameras, PDAs, MP3s and many other new high tech gadgets are gaining popularity, so is the demand for a higher capacity rechargeable battery.  Often you will find some of the “high capacity” cells do not last very long in these high tech devices, this is because some of these cells have a higher voltage output but do not have the lasting power.  It is best to use the small output but longer lasting cells for these high tech devices.  The iPowerUS 2100mAh is specifically designed for digital cameras and other high tech devices , because the voltage demand is well within the battery’s operating level, that is why many users discovered that they can go a long way before recharging, surpassing many other 1800mAh or 2000mAh cells.

5.     Should I use fast charger or slow charger (over night charger) for charging the Ni-MH cells?

If you use a fast charger, make sure it has a Negative Delta V control, they are also called “Smart Charger” and a trickle charging function is a must to protect from over-charging.  The iPowerUS FC-301 and FC-501 are all Fast Smart Chargers that will safely and quickly charge your Ni-CD and Ni-MH cells.  Depending on usage, there is no difference in the life of the battery if you use a “Smart” fast charger. 

6.     Is all Fast chargers created equal? 

No.  There are many types of fast charger on the market today.  Some of the fast charger is timer controlled; therefore, there is no way to know if the battery is fully charged.  Some uses voltage control, these types can charge the batteries to about 80% full.  The iPowerUS Fast Smart Chargers all use the newest technology with programming IC and Negative Delta V to detect the condition of the batteries and are able to charge the batteries to 95% of its capacity.  It will prolong the life of the battery and even revive old and weak battery back to life. 

7.     Is it necessary to discharge the Ni-MH cells before storing them?

Just the opposite.  Before storing the Ni-MH cells, it is best to charge them fully, this will prevent the crystallization of the electrolyte and this is best done every one to two month in order to keep them “fresh.”  The iPowerUS Ni-MH rechargeable battery using a new recipe so that memory effect is eliminate by 95% making discharging unnecessary.  It is only necessary to discharge Ni-CD cells every ten recharging cycles.
