Teach you correct rechargeable batteries) series of nickel (a: avoid overcharge
In charge, the most important yes make batteries and however. In the use of quick charger, choose a quality cont-rol, can precisely control the charger is key to recharge current. But the constant-current charger (slow filling) no control circuit, we need to recharge the battery capacity and different, according to the current “charge time = 150 C/charging current” formula calculates, avoid excessive rechargeable battery cause damage to the battery. For example, battery capacity for 1000mAh, charger, just 130mA for charging current charge for 1.5 * 1000/130 = 11.5 (h
Teach you correct rechargeable batteries) series of nickel (2: in pairs
In use rechargeable batteries, suggest you had better be with the brand, with a capacity of the battery, with annual awards for the same kind of equipment, and put them together in charge. Had better not mix of different brands and the capacity of the battery. This is mostly out on the market cost and volume of the charger, not on a single battery charging and independent control of independence, but two batteries series after the same group of charging and access control circuit. This series of two batteries charging electric current and charging time are the same, if the two different series, or batteries battery capacity in the soc have differences, including capacity smaller or more battery remaining power must first full of electricity. Such batteries due to another team has filled, charger will continue to batteries, which inevitably leads to the full power battery overcharge, heat, thereby, serious damage to the battery or explosion. (this view of the charger for now, seemed a bit outdated. Brand charger all support a single charge – I know there is tasted, super
Teach you correct rechargeable batteries) series of nickel (3: reduce memory effects
Chromium and nickel nimh batteries memory effects cannot be ignored, battery capacity with the increase of number of charge. Especially when they used in the DC power larger or camera, when batteries and partner of residual electric power output, already cannot satisfy the requirement of residual electric equipment. Accumulate, will increase battery memory effects.
To reduce battery memory effects, the easiest way is to discharge of rechargeable batteries. For battery discharge also have certain skills. First, absolutely cannot use short circuit batteries are negative or with large current method of discharge NaDianZu rechargeable batteries. Because, when will produce very big short-circuit current which may cause damage to the battery, the battery electrodes. At the same time, large discharge current also can produce a lot of heat, may damage the batteries battery into electricity. The proposal will be smaller devices in nature, such as MP3 or discharge radio. When the equipment used to boot, or when discharge is almost. This is not excessive discharge, also avoid anti-shocking damage.
Teach you correct rechargeable batteries) series of nickel (4: about self-discharge
For rechargeable batteries, especially large capacity rechargeable batteries, self-discharge phenomenon is very serious. Battery in power after the circumstances, without loss of power will naturally. Now some of the large capacity battery 2000mAh above, be full of power, the capacity of 3 days, placed in nominal capacity is half done. Due to the great now self-discharge battery materials and structure of the direct relationship, there is no way to reduce its properities coefficient, so we can only by changing used to solve this problem
Teach you correct charge (5) series of nickel battery charger, fast and slow charger
According to the speed of rechargeable battery charger, can be divided into slow chargers and quick charger. Slow chargers and quick charger and no obvious limits, but and use rechargeable battery chargers and the volume.
Whether or 1600mAh, 1200mAh battery is defined as the capacity are in charge, and Australia is less than 0.1 C charging electric current, Juan flow for charging. Rechargeable batteries for 0.1 to 0.2 C, charging for slow than 0.2. Charge current than 0.8 C C for rapid charging, while charging current more than 0.8 C for super-fast charging. 200mA namely, for the current 800mAh battery, the battery for 0.25 C, for the current rapid charging, for 1600mAh of rechargeable batteries, and its current for 0.125 C, just for slow. (I also saw charging here know how long the definition, filling knowledge!)
Teach you correct rechargeable batteries) series of nickel (6: slow and fast filling their respective advantages and disadvantages
A slow charger
Advantage: the charging current smaller, less heat charging process. Even a short time, the battery charging calorific value is not too large for battery capacity and life, less damage.
Faults: most no corresponding control circuit, cut off power supply, battery charger only will not end charging. Recharge time is too long, can test your patience.
Second, quick charger
Advantages: charging speed.
Faults: in order to avoid rapid charging the battery, the damage of heat at fast automatic charger using various methods to reduce the temperature when charging battery. The most commonly used method is cosine. This method of current like cosine wave variable dissolve the accumulation of heat, so the battery temperature control in a certain range. In addition, in order to solve the problem rapidly overcharge charger typically use the voltage gradient judgment methods to judge whether the battery to fill. When the battery charger, fast to full control of the circuit automatically turn Juan flow of battery charging pattern, Juan flow charging. Juan flow to charge the battery charging very full, also need not worry too, also do not have to go to the calculation time, make quick charger, thus greatly improving the usability and make quick charger price often higher than slow charger.
