NiMH Trickle Charger with Status Indication
Siva Periasamy, Tony O'Byrne
In spite of the considerable media attention to the concept of recyclable power sources, usage of rechargeable Nickel-Metal Hydride (NiMH) cells has been limited. The combined charger and cell cost have been a mitigating factor in favour of primary cells. The high internal impedances of primary cells are not suitable for the surge currents needed for digital cameras, DC motors and walkie-talkies. NiMH cells exhibit low internal impedances and, as such, are particularly viable in these applications.
