1. Product Descriptions
Product Name: Ni-CD AAA 100mAh Battery
2. Attention To The Storage Of Batteries
● Please store the battery in a cool, dry place.
● Long term storage (for example, more than 6 months) should be charged 3 times with a small current to restore the saturation capacity.
● When the battery is full or half full, do not store a large number of batteries.
● Do not mix metal objects with batteries in storage or transport of batteries to prevent accidental short circuits

5. Nickel-cadmium Battery Charging
The NiCd battery is charged at a constant current in the range of 0 05C to more than 1C. Some low-cost chargers use absolute temperature to terminate charging. Although simple and low cost, this method of charge termination is not accurate. A better way is to stop charging by detecting a voltage drop when the battery is full. The -OV method is most effective for NiCd batteries with a charging rate of C .5C or higher. The -OV charge termination detection should be combined with the battery temperature detection because the aged batteries and mismatched batteries may reduce OV.
By detecting the temperature rise rate (dT/dt), a more accurate full charge detection can be achieved. This full charge detection terminates better than the battery at a fixed temperature. A charge termination method based on a combination of OT/dt and -OV prevents battery overcharge and extends battery life.
Fast charging improves charging efficiency. At a 1C charging rate, the efficiency can be close to 1.1 (91%), and the time to fill an empty battery is a little over 1 hour. When charging at 0.1C, the efficiency drops to 1.4 (71%) and the charging time is about 14 hours.
Because the NiCd battery has a power reception level close to 100%, almost all of the energy is absorbed during 70% of the start of charging, and the battery remains unheated. Ultra-fast chargers use this feature to charge the battery to 70% in a matter of minutes, charging at a few C current without heat generation. After charging to 70%, the battery continues to charge at a lower rate until the battery is full. Finally charge is terminated with a turbulent flow of 0.02C to 0 1C.
