If you use different batteries with actual capacity, with different self-discharge rate of batteries from different manufacturers, you will perhaps throw further described charger. Because each cell can be discharged separately recharge, can be charged with varying articles carrying charge. All of the described nabíjely NiCad battery chargers, or even be discharged all the articles (or group of cells) simultaneously. Such a charger is convenient to use if they are battery cells used in approximately the same capacity. It is met only with new and very long in storage batteries and battery assembled modellers, who can work with a collection of articles.

Collection of articles is quite time-consuming work, and so we, the other current users, we sort the batteries usually only criterion of good-bad. Then it may happen that one device will meet the batteries with different capacity and different self-discharge rate. With the smallest capacity batteries suffer from the culling - are being discharged to zero voltage and sometimes even reverse polarity, thus significantly reduces the number of charge cycles and shortens their life. This danger is especially for batteries with more cells, which discharged a total of one article can not be easily distinguished from the perimeter indicating a slight discharge the entire battery. The batteries have the greatest capacity on the contrary, according to the myths cherished memory effect manifests itself, since they usually are not charging the battery is completely discharged.
The problem with using such battery charger described partly addressed. After inserting the batteries, the batteries are discharged separately to the first voltage of 0.9 V and only then recharged. Can be recharged up to four AA (R6, "pencil article"). The smaller number of cells is one in which the position of an article is added, which remains empty. The first position is the backup status flip-flop circuits in a power failure, and therefore it should always be fitted article. Otherwise, the positions are completely equivalent. Charging is slow stream of...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
