The Primary Use Explanation For Rechargeable Batteries To
Ni-MH battery charging current is more appropriate 0.1C-0.5C
, 0.1C is larger than 2C or less than the charge current may affect battery performance, shorten battery life.
Battery charge or over discharge will cause the battery performance degradation, poor performance.
NiMH batteries:
1, not the depth of discharge, is prohibited, the light bulb or a resistor to discharge the battery completely discharged!
2, is strictly prohibited on just the battery with a charge again force
3, prolonged lack of electricity can not be saved, it should be kept charged and recommended a long time do not use the battery every 3 months to one charge.
Why smart charger will take some time and not immediately able to determine just fully charged battery?
This is determined by the judge of the charger. Now more mainstream and accepted way to judge the accuracy is mainly - V and 0 V, it is generally in the high-end chargers are the main way to judge these two, but the battery into the charger and start charging, no matter battery electricity or no electricity, is not fully charged, the battery will not occur immediately or appear adequate amount of - V or 0 V, it takes time to appear, or the judge said that sufficient charger - V or 0 V, so the smart charger will take some time but did not immediately determine the battery is fully charged.
Instead, use the lowest level of the voltage comparator means to judge the charger can determine in a short time "full power" of the battery, because the voltage comparator voltage battery charger only judge, so long as the battery voltage is reached, it is not will control the battery is not really been filled, all judged as "full" of. Usually, to achieve that from the saturation voltage of the battery there is a lot of space, which are basically not really filled. Therefore, such judgments are normally only at the lowest level of the charger used.
In order to avoid short circuit, the battery and the coins or other metal objects with string keys on the same pocket, to make use of the battery box store.
During charging or discharging the battery is definitely hot, because there is no 100% conversion efficiency, or rechargeable battery charger
When charging, the battery consumption of energy certainly greater than the actual stored energy, that is, the energy consumption of> batteries stored chemical energy. Follow the ability of conservation, more energy will not suddenly disappear, but converted to heat up.
Late charge (that is close to full time), battery temperature, shoot, this is normal, because the basic completion of the chemical reaction inside the battery, the battery unit time stored chemical energy to reduce more energy to heat, so the battery temperature shoot, this also can be used as a sign the battery is full.
