Ni-Mh 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
