Detailed Product Description

Overview

Aselectronic products have come to feature more sophisticated functions, more compact sizes and lighter weights, the sources of power that operate these products have been required to deliver increasingly higher levels of energy. To meet this requirement, nickel-metal hydride batteries have been developed and manu-factured with nickel hydroxide for the positive electrode and hydrogen-absorbing alloys capable of absorbing and releasing hydrogen at high-density levels for the negative electrode. Compared to Ni-Cd batteries, Ni-MH batteries have about twice the energy density and a similar operating voltage.

Features

A. Green power
Ni-MH batteries are free of Cadmium and mercury. They are an environmental friendly chemical power source.

B. Similarity with Ni-Cd batteries
These batteries have similar discharge characteristics to those of Ni-Cd batteries.

C. Double the energy density of conventional batteries
Unitech Ni-MH batteries have approximately double the capacity compared with Unitech standard Ni-Cd batteries.

D. Cycle life equivalent to 500 charge and discharge cycles
Like Unitech Ni-Cd batteries, nickel-metal hydride batteries can be repeatedly charged and discharged for about 500 cycles(IEC 61436 charge and discharge conditions).

E. Rapid charge in approx. 1.2 hours
Unitech Ni-MH batteries can be rapidly charged in about an hour using a specially designed charger.

F. Excellent discharge characteristics
Since the internal resistance of nickel-metal hydride batteries is low, conditions for high-rate discharge up to 4CmA is possible, similar to Ni-Cd batteries. Types and applications In order to widen the useful applications of the Unitech Ni-MH cell and to use its advantages to the fullest, special purpose types have been developed. Detailed characteristics of special purpose batteries are shown eleswhere as individual data sheets.
