A common problem with portable devices is the gradual decline in battery performance after the first year of service. Although fully charged, the battery eventually regresses to a point where the available energy is less than half its original capacity.
Batteries have been known to cause more worry, sadness and frustration than any other component of a portable device. Because of its relatively short life, the battery is also one of the most expensive and least reliable. In many ways, is a characteristic of the battery humanlike: it needs a good diet, moderate, preferably room temperature and with the nickel-based system that requires regular exercise to avoid the phenomenon called " memory. "How to restore and prolong nickel-based batteriesAre known for nickel batteries, the word "memory" in mind. Memory was originally derived from 'cyclic memory' and means that could one nickel cadmium (NiCd) batteries remember how much energy was needed and would provide similar amounts in future releases. Improvements in battery technology have virtually eliminated this phenomenon. The modern concept of "Remembrance" is a crystalline formation, which deprives the battery capacity. Apply one or more full discharge cycles can often reverse this effect.The active material of cadmium in a NiCd battery is in finely divided crystals. In a good cell, these crystals remain small, the maximum area. Memory means that the crystals grow, the reduction in the area. In advanced stages, the sharp edges of the crystals entering the separator, launching large self-discharge or an electrical short circuit.The effects of crystal formation is most visible when a NiCd battery is left in the charger for several days, or if repeatedly recharged completely discharged without intervening. Since most applications do not use any energy before recharge, a periodic discharge 1V/cell (known as exercise) necessary to prevent memory.All NiCd batteries in regular use and in standby mode (sitting in a charger for operational readiness) should be performed once a month. Between these monthly exercise cycles, no maintenance is required, and the battery can be used with any desired user pattern without memory issue.If no training is a NiCd for three months or longer applied, the crystals themselves rooted, so to break even more difficult. In such cases, the training time is no longer effective in restoring a battery and reconditioning is required. Regeneration is a secondary discharge, which slowly removes the remaining battery energy by draining the cells close to zero volts. NiCd tolerate a small amount of inversion of cells. During discharge, caution must be applied in order to stay within the allowable current to minimize cell reversal.Has been introduced with nickel-metal hydride (NiMH) in the 1990s, there were a lot of publicity around its free status of memory. Today we know that NiMH suffers from memory, but to a lesser extent than NiCd. No scientific research is available that provides an optimum maintenance. If a full discharge once every three months appears right. Due to the shorter life span, is the practice of non-NiMH recommended.Racing fans remote control (RC) have experienced all sorts of methods to maximize the battery. One technique that seems to work is zapping cells with a very high pulse power. Positioning the cell voltage is 20 to 40 mV increased under load 30A. According to experts, the voltage gain is stable, only a small drop is observed with use and age.During the race the motor draws 30A from a 7.2 V battery This calculates to about 200W, or power nearly a quarter. The race lasts about four minutes.According to experts, zapping works best with NiCd cells. NiMH cells have been tried, but results are inconclusive. Zapping is made with a 47 000 mF capacitor charged to 90V. The best results are obtained when the battery is run twice after treatment and again zapped. Once operational, zapping is no longer improves performance of the cell. Or zapping regenerate a cell that has become weak.Companies specializing in zapping Toshiba PA3534U-1BAS batteries use high-quality Japan-made NiCd. The cells are normally sub-C and are selected from the factory. Specially marked, the cells are in a discharged state with open cell voltage of 1.11 to 1.12. If at 1.06V, the cell is suspect and zapping does not work well.There is no obvious side effects to zap, but the battery manufacturers remain binding. No scientific explanation stands and little is known about the longevity of cells after treatment.To prolong lithium batteriesBattery research is focusing heavily on the chemistry of lithium, so that it can be assumed that all future lithium batteries will systems. In many ways, lithium-ion (Li-ion) chemicals superior to nickel and lead-based.A lithium-ion battery provides 300-500 discharge / charge or two to three years of service from the time of production. The loss of battery capacity occurs gradually and often without the knowledge of the user. There is no cure for Li-ion batteries to restore, if worn.Li-Ion takes part rather than a full discharge. Do not completely discharge the battery too often. Instead, the higher the load or use a larger battery. There is no memory to worry.Although lithium-ion is free in terms of performance deterioration, engineers often refer to the "digital memory" in batteries with fuel gauge. Repeat with small shocks allow the following expenses are not necessary to calibrate, to monitor the chemical battery with fuel gauge. A deliberate full discharge to recharge every 30 charges or so, will solve this problem. Leaving the battery in the equipment of the break point will be running to do. If this is not done, the fuel gauge is more accurate.The aspect of aging is a topic that is often ignored. A clock starts running as soon as the battery leaves the factory. The electrolyte slowly 'eats' the positive plate, which increases the internal resistance. Finally comes the resistance of cells to a point where the battery can not provide more energy, even though the battery may still contain goods.Rate is subject to temperature lithium-ion by time and state of charge. The most harmful combination is full charge and high temperature. If possible, store the battery in a cool state of a 40% load. Figure 1 shows the capacity loss as a function of temperature and charge state.Simple guidelines- Avoid frequent full discharges, recharge Li-ion more often. There is no memory to worry.- Although the free memory, applying a deliberate full discharge once every 30 days on batteries with fuel gauge to calibrate the battery ACER BATCL50L. If this is not done, the fuel gauge is more accurate.- Keep cool in the Li-ion battery. Never freeze the battery. Avoid a hot car.- For longer storage, remove the battery to 40% SOC.- Avoid purchasing spare lithium-ion batteries for later use. Note the date of manufacture. Do not buy old shares, even if sold at liquidation prices.How to prolong the recovery and lead acid batteriesLead-acid battery, such as Valve Regulated Lead Acid (VRLA) is known, is being developed with a low potential surge. This is done to prevent dehydration. Therefore, these systems are never completely charged and some sulfation will develop over time.The load limit of ideal voltage is critical. Each voltage level is a compromise. A high voltage limit produces good battery performance but shortens the service life due to grid corrosion on the positive plate. The corrosion is permanent. A low voltage battery power and to protect the load at a higher temperature, but is due to the sulfation on the negative plate.Restoring a sulfated battery is difficult and takes time. A method that provides very good results, is the application of a load to a load. It will be fully charged by a battery, then remove the fact that a rest period of 24 to 48 hours and apply a load again. This process is repeated several times, and the capacity is again checked with a full discharge. The lead acid battery is capable of accepting a bit overwhelming, but too much cause corrosion and electrolyte loss.Apply a load surge of up to 2.50V/cell for an hour or two can also reverse sulfation. During treatment, the battery must be kept cool and careful observation is necessary. Prevent bleeding. Most plastics VRLA vent at 34 kPa (5 psi). Not only escaped gas can deplete the electrolyte, they are highly flammable.Sealed lead-acid batteries are available as cylindrical. The Cyclone by Hawker looks like an oversized D-cell size. If sulfated, creating a higher charge voltage often reactivated the cell. The first, the cell voltage to rise to 5V, absorbing only a small amount of power. After about two hours, the small charging current converts the large sulfate crystals back into active material. The internal resistance of the cell decreases and normalizes the charging voltage. When you begin to accept within 2.10V to 2.40V, the cell of the normal fee. If the sulfation is advanced, this remedy does not work and the cell must be replaced.In the application of the outbreak, current limiting must be applied. Be sure to reduce the limit to the lowest setting, feeding practice and observe the battery voltage and temperature during charging.Improve the capacity of an old lead-acid battery with the bike is mostly in vain. Such a battery can be easily carried and cycling for transport further. The lead acid battery SONY VGP-BPS13 / Q is not affected by storage.VRLA batteries are commonly used during a 20-hour-discharge assessment. Even with such a rate, with a capacity of 100 percent is difficult to obtain. For practical reasons, the battery, a 5-hour discharge when servicing these batteries. This typically occurs 80 to 90% of rated capacity. VRLA cells are generally overestimated, and manufacturers are aware of this practice.
