Battery Batch

Here are some quick tips on how to charge nimh battery ( nickel metal hydride battery) One of the preferred charging methods is the “delta-V” method, according to Panasonic and other battery manufacturers. This is illustrated in the “NiMH Charge curve” figure. The battery is rapidly charged at constant-current, at a high rate of “1C”. After the battery is fully charged, and as it begins to overcharge, the voltage polarity of the electrodes inside the battery will begin to reverse, and this will cause the battery voltage to decrease slightly.
