Battery Characteristics
Main features of Ni-MH batteries
Main features of Ni-MH batteries: charge characteristics,
discharge characteristics, life cycle characteristics, storage characteristics
and security characteristics
1.charge characteristics
Charge current, time temperature and other factors
influence the charge characteristics of Ni-MH batteries. The charge voltage
will rise when charge current increases and the charge temperature falls. Charge
efficiency will change as the charge current, time and temperature change. In
terms of quick charge, it is necessary to be equipped with the charge control
system. Please refer to the following charging methods.
Typical Charge characteristics (The temperature influence
the charge voltage)
2.discharge characteristics
Discharge characteristics of Ni-MH battery will change as the discharge current
and temperature change. In general, compared with the primary batteries the
Ni-MH batteries have little change in the process of discharge. Although
discharge current is very high, the damage of capacity is neglectable.
The "P" series batteries in Mike is specially designed for meeting power
tools which need high current discharge. In addition, our quick charge
batteries with high capacity are specialized in R&D and production for
satisfying the high capacity demand of high-tech installation.
3.Life cycle characteristics
The life cycle of Ni-MH battery is influenced on charge
and discharge principles, temperature and methods. When charge and discharge
according to IEC standard, the life cycle of charge and discharge will exceed
500. Different charge methods such as quick charge and charge in the operating
will influence the real life cycle of batteries.
Typical life cycle characteristics
4. storage characteristics
|
When Ni-MH batteries are
stored under the condition of charge, the capacity will have losing
(self-discharge) and the damage degree will increase when the temperature
rises. Certainly the capacity losing will be recovered through charging.
Although batteries are stored for so long time, the capacity will be
recovered if the storage environment is appropriate. |
5.security characteristics
If batteries used improperly, such as overcharge, short circuit and reversed
charge led to higher internal pressure of the battery, a recoverable
safety-vent valve will open in order to decrease the internal pressure so that
prevent the battery from exploding.
The Specification of Ni-Mh
Three specs of McNair Ni-MH batteries
(1). General type (Standard)
Features
A. Long life cycle
exceed 500 charge and discharge cycles
B.Avoid maintenance
Simple operation like primary batteries but avoid
overcharging and overdischarging (-20℃～+60℃)
C. Stable performance
low can be applied to a large range of temperature
Applied examples A. Intercom, wireless phone
B Measuring tools, calculator
C. remote control auto and other power toys
D. Photographic light, searchlight, lawn light
E.Appliances: power shaver, recorder
(2)High capacity type
Features
A.Long life cycle
exceed 500 charge and discharge cycles
B.high current
To meet discharge in 5C (AAA、AA、A）、discharge in 10C （SC、C、D）)
C. To substitute 1.5V primary battery
Although its nominal voltage is 1.2V, this type of
batteries can be completely applied to the equipment with 1.5V primary.
Applied examples A. Appliances: power shaver, recorder and so on
B.Earphone stereo system, CD player, radio, DVD, MP3, Digital Camera and other digital
products、 wireless phone.
C.Measuring tools, calculator
(3)High power discharge type
Features: A. Excellent discharge performance at high current
Based on the rating capacity with 0.2C discharge, discharge in
5C can reach 95% and discharge 10C can reach 85%
B.Quick charge performance
charge in 1-3CmA current
C.Low Internal Resistance
D.Long life cycle and excellent reliability
Applied examples A. power tools: electric drills,
screwdriver and electric saw and so
on
B.Power toys: electric auto, electric plans, electric bicycle, electric trochlea
and so on.
C.Video cassette recorder
D.Other equipment in high power discharge
