Nickel Cadmium Batteries Ni-Cd batteries have been developed to meet a wide range of user needs, ranging from low current level usage like emergency power sources to very high power applications such as cordless drills, etc.
Features:
Long service life and economical
These cells can provide more than 500 charge and discharge cycles. This makes it extremely economical, and provides an expected life similar to that of the device in which it is used.
Excellent discharge characteristics
Ni-Cad batteries have low internal resistance and high, flat voltage characteristics during strong current discharge, which ensures a wider application field.
Long shelf life
Provides long storage life with few limiting conditions. It offers problem-free charge after long storage, permitting to use in a wide range of applications.
High-rate charging
For those applications that require it, the cells can be quick charged or rapid charged in 1-2 hours. Ni-Cd batteries can be fully charged in 1.2 hours.
Reliable, self-resealing vent
Each cell is equipped with a self-resealing safety vent that provides safety and maintenance-free function. The cell can be used in any desired position during charge, discharge or storage.
Wide application field
Batteries with capacity from 100mA to 7,000mA are available.
Applications:
Gauges
Calculators
Photographic Lights
Household Applications
Power Tools
Toys/RC Cars
Emergency Lights
Telecommunications

Lithium Batteries Historically, lead-acid, nickel-cadmium (Ni-Cd), and nickel-metal hydride (Ni-MH) batteries have been the conventional choice for small-sized rechargeable batteries. In line with the recent trends toward mobile and cordless electronic equipment, rechargeable batteries are required to provide higher energy density to meet the needs of ever smaller and lighter devices. Moreover, the attention being focused on protecting the environment has resulted in demand for products that are environmentally friendly.
Features
1. High Energy Density
The weight of a lithium ion battery is approximately one half compared to a nickel-cadmium or nickel-metal hydride battery of similar capacity. Moreover, the volume of the lithium ion battery is 40 to 50% smaller than that of a nickel-cadmium and 20 to 30% smaller than that of a nickel-metal hydride battery.
2. High Voltage
A single lithium ion cell has a voltage of 3.7V (mean value), which is equal to either three nickel-cadmium or nickel-metal hydride cells connected in series.
3. Pollution-free
The lithium ion battery does not contain any polluting substances such as cadmium, lead, mercury, etc.
4. Non-metal Lithium
The lithium ion battery does not employ any lithium metal. It is not governed by aircraft transportation rules relating to carrying lithium batteries in passenger airplanes.
5. Long Cycle Life
Under normal conditions, the lithium ion battery has a life of more than 500 charge/discharge cycles.
6. No Memory Effect
The lithium ion battery is free from the so-called memory effect, a phenomenon seen in nickel-cadmium in which the apparent battery capacity decreases when shallow charge and discharge cycles are repeated.
7. Fast Charge Capacity
The lithium ion battery can be fully charged in 1 to 2 hours, using a constant-current / constant-voltage (CC/CV) type dedicated charger with a rated voltage of 4.2V per cell.
