[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 ...

See Figure 6. The design example will be a 1-A battery charger system for two NiMH cells with the TH1050AA from Toshiba selected as the cell. The maximum voltage at full charge is approximately 1.5 V ...

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.

For example, if a USB or 5-V regulated input charges a three-cell NiMH battery pack ... microcontroller's ADC senses the battery's output voltage. Fig. 6 shows a simplified block diagram of ...

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 — ...

A rechargeable battery that can be fully charged in just 6 minutes, lasts 10 times as long ... types of battery such as nickel-metal-hydride (NiMH) and nickel-cadmium (Ni-Cd) types.

When we saw [Max.K]’s automatic NiMh battery charger float past ... A motorized cam with a battery shaped insert picks up a cell from the bin and moves it into the charger contacts, before ...

Compare a nickel metal hydride (NiMH) battery. At 1.2V per cell, ten cells would be the obvious choice for a 12V battery. However, many NiMH cells are only really fully discharged at perhaps 0.9V, ...

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 ...
