What is a Nickel-Cadmium Battery?

It's a battery that uses nickel oxide in its positive electrode (cathode), a cadmium compound in its negative electrode (anode), and potassium hydroxide solution in its electrolyte. The Nickel Cadmium Battery is rechargeable, so you can use it over and over.

Features

It's rechargeable, so you can use it over and over (more than 500 times.)
Much more economical than dry cell batteries.

Discharge voltage remains stable even in conditions of high-rate discharge current.
For equipment needing a high-rate discharge current, it's far more stable than other battery types.

Wide operating temperature range (-20c to 60c.)
It operates especially well in low temperatures.

Performance doesn't deteriorate even after long-term storage.
Full recovery of original performance levels after recharging.

Designed to withstand overcharge and overdischarge.
Superior durability.Sealed configuration with gas release vent.
Easy maintenance and no leakage.

Applications

Telecommunications equipment
Industrial equipment
Emergency lights
Electric tools
Battery-powered vehicles
Shavers, electric toothbrushes

What are Nickel-Metal Hydride Batteries?

It's a battery capable of charging and discharging that can save twice as much energy as an ordinary Nickel-Cadmium Battery. Nickel-Metal Hydride Batteries uses hydrogen absorbing alloys in its negative electrode (anode) and nickel oxide in its positive electrode (cathode).

Features

Double capacity of standard Nickel-Cadmium batteries.

Can be used over and over (more than 500 times with a specific charger).

Compatible with Nickel-Cadmium batteries (almost same discharge voltage).

Applications

Notebook computers
Cellular phones, PHS phones, telecommunications equipment
Video cameras, digital still cameras, PDA
Laptop computers
Shavers, electric toothbrushes
Various portable equipment

What is a Lithium-ion Battery?

It's a high energy density, 3.6v/3.7v battery that is not compatible with ordinary batteries, but is widely used in the portable equipment market. It uses lithium metallic oxide in its positive electrode (cathode) and carbon material in its negative electrode (anode), and the lithium ions inside the battery transfer between the positive electrode and the negative electrode during charge or discharge.

Features

High voltage of 3.6v/3.7v lets you cut down on the number of batteries you use.
High energy density minimizes battery size and weight, making it perfect for use in small portable equipment.
No metallic lithium is used so charging and discharging are very safe.
No memory accumulation so it provides a full charge every time.

Applications

Video cameras, digital still cameras
Cellular phones, PHS phones
Laptop computers
MD players
Various portable equipment
PDA

What is a Lithium Battery?

It's a battery that uses lithium metal or a lithium aluminum alloy in its negative electrode (anode) and manganese dioxide in its positive electrode (cathode).
