Simple Cell Phone Battery Maintenance

The principle is very simple, when the electricity will not be responsible or electricity when charging, it is preferable not to have power when it is charging. VGP-BPS9 VGP-BPL8

The new batteries when used 5.6 times, the drums began to play at peak performance. Some chargers have a discharge function, mobile phones, the battery must be the remaining capacity that moment all the glory, and then gave the charge. (This is to remove the battery in the memory function for the different materials of different time intervals battery)

Charging the battery is full, you can win coming, there is no specified time that argument:

*** Not to say that over the load better.

Function to protect the charger when the battery reaches a certain state, which is showing the battery charger has been completed, then re-load when it is completed to enter and to protect the battery charger function began, the battery will no longer accept foreigners The current, long rechargeable battery can only give a negative, so eat the F2024B F4486B battery on the charger does not charge.

*** The best win for charging the battery.

Many of my friends like to take a trip red, regardless of when, as the cell phone when the power is not enough, he immediately poor, such a practice never to play can not be the best battery performance , battery charger to bring it down and put inside the standby red relatively long, which is recharged when current strength of a relationship.

Note: For lithium batteries, because mobile phones are essentially the main battery:

1. No need to ensure that whenever a new full release END electric charge;

2. A period of time to make a protection circuit placed under the control of the profound power of the FK890 C1295 battery charge to change the statistics, but it will not increase the actual capacity of the battery;

3. A long time without the battery must be placed in the shade to weaken its internal autonomy, the reaction rate passivation;

4. Protection circuit is also capable of monitoring battery discharge, in the long term without the battery must be charged to a certain degree of power to prevent self-discharge of batteries for storage in the discharge of excessive lead to excessive damage to the A1185 A1045 battery.

Talk about photovoltaic battery

Photovoltaic battery works:

Solar batteries through the photoelectric effect or photochemical effects of light energy into electrical energy directly to the camera. The photoelectric effect to work in thin film solar batteries solar for the general public, the working principle of photochemical effects of solar VGP-BPS9 batteries is still embryonic. Solar radiation in the pn junction semiconductors, the formation of new hole - electron pairs. The electric field in pn junction under the influence of flow hole area n area P, the flow of N e of the p-area, connected to the circuit after the training course.

Photovoltaic batteries Introduction:

The solar photovoltaic batteries (PV batteries for short) are used for the sun’s light energy directly into electrical energy. Currently a large number of terrestrial PV systems based on silicon substrate using silicon solar batteries can be divided into monocrystalline silicon, polycrystalline silicon solar batteries in amorphous silicon. In the performance of energy conversion and the lifetime of an overall performance, monocrystalline silicon and polycrystalline silicon batteries are better than amorphous silicon batteries. Below conversion efficiency of polycrystalline silicon, but the price cheaper.

As required by the application after a certain combination of solar batteries to achieve a certain level of output and nominal output voltage of a group of photovoltaic VGP-BPS10 batteries, called PV modules. Depending on the size and scale photovoltaic power plants, a variety of PV modules can be composed of a variety of sizes.

PV modules using monocrystalline high-performance photovoltaic batteries or polycrystalline silicon, high transmission tempered glass, Tedlar, more corrosion resistant alloy chassis and other aluminum materials, the use of processes leading to vacuum lamination process and welding pulse. Even in the harshest environments can ensure a long life.

The installation of set up is very convenient. Components installed in the north watertight junction box, through which it can be easily connected with the external circuit. For each piece of solar Laptop battery components, are guaranteed over 20 years of life.

The main factors affecting the life of the lead-acid battery

⑴ temperature greater impact on the battery. The ambient temperature is too high, the battery will overload produces gas, the temperature is too low, the battery will be pretty cool, it will affect Laptop battery life. Therefore, the general provisions of the ambient temperature around 25 ℃, UPS is also float temperature setting voltage. Practical applications, the battery is generally 5 ℃ ~ 35 ℃ in the office, below or above 5 ℃ to 35 ℃ will greatly reduce battery capacity and shorten battery life.

⑵ deep discharge of battery life also has a great influence. More depth of battery discharges, less the number of recycling activities, and should therefore avoid the use of depth of discharge. Although the UPS has a battery low protection potential, the general single-cell, when discharged to 10.5 V or more, UPS will automatically be closed. However, if the UPS is lightly loaded or discharge any discharge load may cause the depth of battery discharge.

⑶ batteries in the storage, transportation, installation, following the loss of part of the self-discharge capacity. Therefore, after installation before commissioning should be based on the open circuit voltage of the IBM ThinkPad T40 battery to determine the remaining capacity of the battery, then a different approach to supplement charging batteries. Set aside extra batteries every 3 months should be an additional charge. Perhaps by measuring the voltage of the battery open circuit to determine if the battery is good or bad. For 12 V batteries, for example, if the open circuit voltage is above 12.5 V, the energy storage battery, said there are more than 80%, if the open circuit voltage less than 12.5 V You should immediately supplement charge. If the open circuit voltage less than 12V, the battery stores electrical energy, said less than 20%, the battery useless.

⑷ battery charge and discharge generally expressed C, C is the actual value associated with the battery capacity. For example, batteries 100AH, C = 100A. Matsushita Lead-acid maintenance-free battery charging current is 0.1C best on the market, the charging current can not exceed 0.3c. Charging current is too large or too small will affect battery life. The current requirements for general discharge of 0.05C between ~ 3C, UPS, normal use can satisfy this requirement, but must also prevent the occurrence of unexpected situations, such as the battery short-circuit and so on.

⑸ Load Voltage. In the work of backup UPS battery, electricity is in the state of charge under normal circumstances, only the power outage is discharged. To extend the Dell Inspiron E1705 battery, UPS shippers typically use constant pressure to limit the control over the way, the battery is fully charged state to float after each section on the current float is set at 13.6 . If the charging voltage is too high causes the battery before charging, the battery is charging less than the contrary. The charging voltage abnormality may be caused by configuration errors caused by the battery or charger malfunction due. Therefore, when installing the battery, the battery must pay attention to the accuracy of the specifications and quantities of different specifications, different batches of cells do not mix. Do not use inferior charger, plus a charger, but also to consider when installing problem of heat dissipation. Currently, to further improve the life of the battery, UPS has developed and adopted a kind of ABM (Advanced Battery Management) three-stage program of intelligent battery management, ie load is divided over initialization, floating charge and rest three stages: the first step is constant load balance flows, recharge the battery capacity to 90%; second stage is floating Chong Chongdian load capacity battery at 100% and then stops charging, third step is a natural discharge at this stage, the battery using its own leakage current discharge, as the minimum voltage required, and then repeat these three steps. In this way, the nature of changes that were previously fully charged, even after the hp PB994A battery during the day to 24 hours of floating state, thereby extending battery life.

⑹ Following the interview without system battery electrolyte absorption in normal use will not produce any gas, but if the user is misused, causing the battery before recharging it will produce a gas, this time pressure increases the battery, battery pressure valve on top of open, burst out a serious cause of the battery.

⑺ UPS running the process, be careful to control the terminal value of battery voltage, current float value, each battery voltage, battery and the DC bus to ground resistance and the insulating state.

⑻ not individually increase or decrease the number of single charge of battery cells, resulting in the ability of imbalance single battery charge and an uneven, reducing battery life.

⑼ the battery must be installed as far as possible in a clean, fresh, airy, dry, and avoid sunlight, radiators or other heat sources of radiation effects. Batteries should be placed on positive legislation, non-tilt. Each battery must be securely connected between the terminals.

⑽ regularly maintained. The battery in use after a certain time should be inspected regularly, as well as observations of their appearance is abnormal, measurement of the battery voltage is average and so on. If you are not a long term power outage, the battery is always in a state of charge, this would allow the activity of the deterioration of the battery. Thus, although power outages, UPS is also needed on a regular basis to test the discharge of the battery to make it active. Discharge test can usually be done in three months, the practice is UPS with a package - preferably 50% or more, then turn off the electricity, so that UPS is able to discharge the battery, the duration discharge by the battery capacity is usually in terms of a few milliseconds to tens of ms, the discharge to resume electricity supply, continue to charge the VGP-BPS9 battery.

Purchase and use common sense of lead-acid battery for electric bikes

First, choose the right direction

1, see product logos are complete. Including the name of the manufacturer, model specifications, date of manufacture, mark, see if they are consistent within and outside the mark, in particular, to check whether there catchy product identification of the body the production date should pay attention if, in the near future.

2, note the appearance of the VGP-BPS2B battery. See if there is a distortion, cracks, scratches, and signs of leaks. Battery terminals should be clean, no rust, signs must be clear.

3, concerned about the electric car batteries rated capacity marked on. More rated capacity marked on the battery discharge time of the longer battery, it is better not to buy non-rated batteries marked, but pay attention to whether a dedicated electric vehicle, if more capacity marking should be based on design capacity shall prevail.

4, choose well-known businesses, large enterprises branded batteries. Batteries are generally provided by a manufacturer of industrial batteries, different brands, different manufacturers of batteries as other advantages and disadvantages, the price level is also divided. Well known, the size of large companies, technological solid after-sales service is good, battery quality assured.

5, corresponding to the purchase and the VGP-BPS10B battery charger with an intelligent automatic. The charger should automatically adjust the size and timing of recharge is beneficial to prolong battery life.

Secondly, the use of common sense

UPS 1, when used in Start electric car, the wind and uphill, it is the best use of manpower to help cars start from simple models of electric car launched in the wind riding up and high winds should be used when the foot help to reduce the battery charge and prolong their life, luxury models should be slow to start electric vehicles

Start step should not be diverted to turn in the late phases of hard acceleration in the descent, you can switch to electric cars to open. When the electricity shortage, they should reduce the speed of cycling, regardless of when they should not be mounted in the power of the state lacks tension.

2, using electric bike, do not overload. Electric bike’s overall design load of 75kg, which is a single person riding overload results in long VGP-BPS13A/B battery high discharge current, which damages the battery, which is the main reason for the shortened life of the battery.

3, should pay attention to the battery capacity over time and circumstances change. In general, with increasing frequency of use, the battery capacity will be gradually decreased. In the case of low temperatures, the battery capacity is reduced when temperatures can be restored later.

4, master the correct method of charging. Battery suitable temperature from 0 ~ 40 ℃, the charge should be at room temperature. Should pay attention to the charger charging status and a normal load of time to prevent the VGP-BPS9 battery due to charging or over charging, charging abnormal was considered necessary to seek professional help as soon as possible to avoid damage the battery. Cooldown after use, preferably fresh daily as a travel over 20 kilometers an office in a timely manner is preferable not exhausted, recharge isoelectric. Long-dormant, it is necessary to add from time to time on the battery.

5, regular maintenance of the battery. Battery life after a long time, if found low battery, especially when fever battery grave or her own maintenance staff should be invited to open the battery cover, remove the cap rubber alone Giga water 5 ~ 15ml, extended battery life. In addition, models, old and new batteries can not be inconsistent with the use of series or simultaneously, the various manufacturers of batteries can not be mixed. Replace the battery, it should be a group of his replacement.

6, attach importance to the pollution of the battery. Suggested that given the designated recycling of waste batteries, do not carelessly discarded in order to avoid environmental pollution.
