WebAug 9, 2024 · The cheapest way to charge a NiMH battery is to charge at C/10 or below (10% of the rated capacity per hour) for 15 hours, and the minimum voltage to get a full charge must be set to at least 1.41 volts per cell at 20 degrees C. This “overnight charging” method does not require an end-of-charge sensor and ensures a full charge. WebThis week Jerry explains why NiMH batteries drain and wont charge, what you can do to prevent it, and who they're for! Stay tuned for more content.If you hav...
