Lightweight and Compact size:

The weight of C2016 is very light compared to other alkaline cells and the size of this cell is ultra-compact. Hence, it is easy to place on small equipment like car remote keys, watches, etc.


Self-discharge rate is very low:

This cell is made of a combination of lithium and manganese dioxide. At all operating temperatures, the self-discharge rate of this cell is very low. After 10 years, it has 90% of its capacity.


Safe and Reliable:

The use of this cell is safe to use in various applications. But we have to store and keep this equipment away from children. It contains lead which make serious harm after swallowing. The life of this cell is good and it does not require to replace for a long time. Hence, it is maintenance-free equipment.
