Nickel Batteries
Current Position: Products > Nickel Batteries    



Rechargeable Nickel batteries are one type of alkaline storage cylindrical battery and classified as secondary batteries. Nickel battery has a positive electrode made of active material-- nickelous hydroxide. As the perfect sealed construction and the efficient charge/discharge characteristics, BYD Nickel batteries provide superior features and practical value in long service life, high rate discharge and stable performance. As a result, they are widely used in many fields such as communication and telephone equipment, office equipment, tools, toys and hobby, emergency devices and consumer applications.


1. Long service life and economical

The cell 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.

2. Excellent discharge characteristics

BYD Nickel batteries have low internal resistance and high, flat voltage characteristics during strong current discharge, which ensures a wider application field.

3. Long shelf life

BYD Nickel batteries provide long storage life with few limiting conditions. It offers problem-free charge after long storage, permitting to use in a wide range of applications.

4. High-rate charging

For those applications that require it, the cells can be quick charged or rapid charged in 1-2 hours. Some models of batteries could be used in 15minnutes charging mode.

5. Wide-Temperature Range

BYD Nickel batteries can be used at extreme temperature from -20℃ to +70 ℃.

6. 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. The battery has passed CE certificate, UL2054 test, its safety is excellent.

7. Wide application field

BYD Nickel batteries with capacity from 100mAh to 15,000mAh are available. With four types available for general use (standard type, consumer type, high temperature type and large current discharge type), BYD batteries can be applied in any cordless equipment.

8. High quality and reliability

BYD have received the DNV certificate of SO14001 、OHSAS18001、ISO9001.
Types and applications

In order to widen the application fields of BYD Nickel batteries and extend its full advantages, some special purpose types have been developed. Detailed characteristics of special purpose batteries are shown in the Individual Data Sheets.

There are four types of BYD Nickel batteries:
