Green batteries drop in to replace nicads

Easby Electronics has a wide choice of nickel metal-hydride rechargeable button cells and batteries which will serve as nickel-cadmium (NiCd) replacements.

Easby Electronics has a wide choice of nickel metal-hydride rechargeable button cells and batteries which will serve as nickel-cadmium (NiCd) replacements.

While offering improved recharging reliability over NiCds, the cells are also cadmium-, mercury- and lead-free and so avoid any user uncertainty relating to future European legislation.

One range is ideal for use where high rate discharging occurs.

Varta Microbattery has a range of high performance nickel metal hydride (Ni-MH) button cells offering long life expectancies, and relative capacity increases of up to 40% over nickel cadmium cells.

As well as coping with continuous overcharging, unlike nickel cadmiums the Ni-MH cells cope much better with repeated recharging when only partially discharged.

A choice of 10 different single cells offers capacities from 16 to 380mAh at 1.2V.

Batteries are available in a range of sizes and configurations allowing choice for particular applications.

The Varta Microbattery HyRate button cells are ideal for high rate discharging applications.

For example, a battery of three V 450 HRs is an ideal power source for DECT and GSM telephones which create high pulse current drains.

The battery is just 6mm deep, has a nominal capacity of 380mAh, and will supply pulse currents up to 2.5A.

Varta button cells and batteries can be installed on PCBs and flow soldered in the charged state.

They are ideal for a wide range of applications, including cordless phones, PCs and notebooks, remote controllers, medical equipment, alarm systems, torches and toys.
