Using the Duracell CEF80NC Charger
The charger is intuitively designed and easy to use. Insert a battery into the charger, and the LED turns red until the battery is charged, at which point it becomes green. Charging fully drained 2050 mah batteries (those included with the charger) tkes me just about 55 minutes. NiMH batteries with capacities of up to 2500mah are also readily available, and I’ve used this charger to charge 2500mah rated Everyready NiMH batteries without problems. These higher capacity batteries take a little longer to charge. Some older 1500 mah NiMH batteries that I own can be recharged in 45 minutes.
Batteries do get a little warm near the end of the charging cycle, I estimate around 40-45 degrees C (104-113F). The number times a NiMH can be recharged is affected by the temperature at which a battery is used and the temperature at which it is charged. Duracell estimated that these batteries can be charged 500 times, and still maintain 80% of their new capacity, if they are used and charged at 70F. If they are used and charged at 100F, the estimated charge cycles drops to 300 or so. Using any fast charger is likely to lessen the number of times you can cycle an NiMH battery, and I’m sure I am affecting the life of my batteries by using a fast charger. Using a trickle charger, which would require 12 hours or more, would be better, but I am willing to accept the reduced number (still 300!) of charge cycles, in exchange for the fast charge times. On the plus side, batteries charged in this unit do not get nearly as hot as they do in an old Rayovac 1 hour charger than I own, it appears the charging rate is lowered near the end of the cycle to minimize heat buildup in the batteries.
