    We offer a wide choice of battery types, with
    various capacity parameters:  
     
     Slim batteries,
    to reduce the weight and the size of the phone device.  
     High capacity
    batteries for a longer (a few days) operation of the phone device, without the necessity
    of a recharge. 
     
      
     
    Three types of batteries are currently used in mobile phones.
    Their most important features are compared in the following:  
     
     NiCd (Nickel-
    Cadmium battery pack) 
    + the highest number of recharging cycles (1 000, approximately)  
    + the lowest price  
    - substantial weight 
    - memory effect  
     
     NiMH
    (Nickel-Metal-Hydride battery pack) 
    provides for 500 recharging cycles, approximately  
    capacity larger by 1/3, as compared to NiCd  
     
     LiIon
    (Lithium-Ion battery pack)  
    + the largest capacity 
    + the lowest weight 
    - the longest recharging period  
    - the highest price
