Usually all the two way radios use a nickel –cadmium battery. These types of batteries are more robust, durable and even if they are not handled properly, they do not wear out easily. The other alternative, which can be used, is a nickel-metal-hydride. A nickel-metal-hydride battery is a two-way radio battery, which contains no toxic metals, and it has a higher energy density.

A comparative study shows that through out their life nickel-cadmium two way radio batteries have high capacity and low internal resistance, on the other hand nickel-metal-hydride two way radio battery starts with good capacity and low internal resistance but the resistance increases after a few hundred cycles.  
  
The Nickel-based two-way radio batteries require a lot of maintenance.  To prevent formation of Crystalline on the plates of the cell a regular discharge cycle is required. This formation is known as memory.

In every 1,2 months Nickel-cadmium two-way radio batteries gets discharged so they need to be conditioned, on the other hand nickel-metal-hydride two-way radio batteries doesn’t discharge for more than three months. Without proper safeguarding, the benefit of nickel-cadmium over nickel-metal-hydride in terms of cycle life cannot be realized.  
Lithium ions can also be used ion a two-way battery. Research has been done and the results are positive for lithium ion batteries. Separate chargers are required for theses type of batteries.  
In our website www.talktwoway.com you can get all theses chargers and at very reasonable rates.
