Suited for long-term use with low current.
For operation at low current levels with long stands intermittent discharge with medium current level provided. The average is not below the active current level.
Bobbin-type or flat cells and temperature range from -55ípC to +85ípC..
Rechargeable Ni-Cd batteries are one type of alkaline storage battery and classified as secondary batteries. Ni-Cd battery has a positive electrode made of nickel hydroxide, a negative electrode made of cadmium , and an alkaline electrolyte. They are designed by IEC 285 as alkaline secondary cells and batteries "Sealed nickel-cadmium cylindrical rechargeable single cells".
EWT Ni-Cd battery meet a wide range of user needs, ranging from low current level usage like emergency power sources for semiconductor memories to very high power applications such as cordless drills, etc.
Features:
Ni-MH battery features the same voltage (1.2V) as Ni-CD, yet twice the capacity.
Wide operational temperature range from -10ípC to 50ípC.
Self-discharge is minimized to levels below Ni-CD for enhanced storage characteristics.
Quick charging in about one hour is possible with a specially designed Ni-MH exclusive charger..
As electronic products have come to feature more sophisticated functions, more compact sizes and lighter weights, the sources of power that operate these products have been required to deliver increasingly higher levels of energy. To meet this requirement, nickel-metal hydride batteries have been developed and manu-factured with nickel hydroxide for the positive electrode and hydrogen-absorbing alloys capable of absorbing and releasing hydrogen at high-density levels for the negative electrode. Compared to Ni-Cd batteries, Ni-MH batteries have about twice the energy density and a similar operating voltage.
