[Jay Kickliter] built his own coin cell battery recharger ... we hate the choice of a disposable battery. All of our less-hip remotes which use AA or AAA have NiMH rechargeables in them and ...

Reduce the voltage at BATT+ by (6 3 1.65 V) with a 10-V zener diode ... 2). It shows a 22-cell NiMH battery being charged in fast-charge mode with a charging current of 0.5 A.

The NiMH AA-cell has an impedance of 25milliohms, while the NiCd Sub-C has an impedance of 6 milliohms. While NiMH AAs could show an initial improvement over the older, well-spent NiCd battery — ...

The weak cell only 1.2W. After 4 hours of charging, the difference in converted energy is 4* (1.3-1.2) = 0.4Wh. The following balancer for Ni-Cd or Ni-MH keeps the battery pack in balance and ...

A new method for recycling old batteries can provide better performing and cheaper rechargeable hydride batteries (NiMH) as shown ... build an electrochemical cell or battery of virtually all ...
