The most commonly used battery for two way radios, NiCd batteries are known and liked for their long life, durability and steady high capacity. Among the main advantages of these batteries we can figure out low cost and high resistance for temperature variations.
The main disadvantage of a nickel cadmium battery is its susceptibility to “memory effect,” meaning that the battery gradually loses its capacity for full recharging if it is repeatedly recharged before its capacity has been fully drained. Because of this, nickel-based batteries (both NiCd and NiMH) are relatively high maintenance.  Read more...
