[Paul Allen] has been working on the latest iteration of his NiMh battery charger and it looks amazing! We’ve covered [Paul Allen]s awesome hacks and tutorials before, but never this project.

It can charge AA, AAA, AAAA, and C batteries, including NiMH and some lithium-based batteries, all with custom charge rates. We confirmed that chargers could charge one battery at a time by ...

With NiMH AA batteries, you have to top them off before use because they lose much of their charge sitting around. And that can be a nuisance. But in the last year, several companies have designed ...

Eventually, the combined effects of environmental problems and increased demand on the batteries led to the development of new battery technologies: nickel-metal hydride (NiMH), rechargeable alkaline, ...

ion or lead acid batteries. Others are suitable for charging nickel-cadmium (NiCd) or nickel-metal-hydride (NiMH) batteries. Important features for battery charger ICs include over-voltage protection ...

The charger supports all of the most used battery types - that is in my opinion NiCd, NiMH, Li-Ion and SLA. Li-Ion and SLA are charged in constant current-constant voltage mode, while Nickel based ...

float resistance = 10.0; //measured resistance of the power resistor int cutoffVoltage = 1600; //maximum battery voltage (in mV) that should not be exceeded float cutoffTemperatureC = 35; //maximum ...

The best rechargeable batteries are much better at holding their charge than they ever used to be. Recent generations of triple-A NiMH batteries are built to hold most of their charge for many months ...
