Ni-Cd Batteries

Advantages and Limitations of Ni-Cd Batteries

Advantages

Fast and simple charge - even after prolonged storage.
High number of charge/discharge cycles - if properly maintained, the Ni-Cd provides over 1000 charge/discharge cycles.
Good load performance - the Ni-Cd allows recharging at low temperatures.
Long shelf life - in any state-of-charge.
Simple storage and transportation - most airfreight companies accept the Ni-Cd without special conditions.
Good low temperature performance.
Forgiving if abused - the Ni-Cd is one of the most rugged rechargeable batteries.
Economically priced - the Ni-Cd is the lowest cost battery in terms of cost per cycle.
Available in a wide range of sizes and performance options - most Ni-Cd cells are cylindrical.
Limitations

Relatively low energy density - compared with newer systems.
Memory effect - the Ni-Cd must periodically be exercised to prevent memory.
Environmentally unfriendly - the Ni-Cd contains toxic metals.
Some countries are limiting the use of the Ni-Cd battery.
Has relatively high self-discharge - needs recharging after storage
