Cell phone lithium battery over-charging approach

You mention it, either because the relationship between buying a Big Nine, large and small Nine Nine cell battery is a model, as are the BST-38. When the boss bought a Big 9 sent a charger is estimated that cottage property or just a little sign, because I have not really seen, and there is no common parts loader. Go home with a moment, I feel pretty good, Dell Inspiron 1150 battery empty, almost more than three hours can be filled. Compared to the previous burden that small nine silent growl Jin (eight hours), this charger is clearly much higher efficiency. So I feel very good.

Result, the problem lies in this very nice top.

Watch the Big 9 Mody electricity, and I put a little touch of the nine panels replaced him, and then use it quickly washed into the nine large panels filled, and must post a small battery is almost used nine released and replaced by a good piece of charge. Then, quickly forgotten to recharge at night when they would be. Pricing of course, no hesitation, and took that fast red. Connect the middle of the night went to bed. Wake up. Time to see the blue light has been completed, and initially intended to overturn the result, too lazy to leave the cover to stand in the morning. Then yesterday night, to help small to 9 per battery, battery change is the piece of board. The results show a small battery-nine volumes of safe, suggesting that the lack of electricity, see the state of only 2% after the battery. Currently, I am a little sad. I forget to recharge? Do not think so continue to consider the red solid cap at the top, showing the burden of red light, I read it I thought, they did not load. (sorry for the four cells are not quite sure) just want to go to sleep, never imagined that after five or six minutes, which suggests that blue light filled, Maybe I know that this is certainly the Dell Inspiron 1100 battery there is a problem. So to win after nine charger with the previous small, taken in the progress of green tips filled - that is, the number of full battery, but the phone can not use up.

According to my understanding of lithium batteries, lithium batteries are generally self-protective function, rarely charge-discharge excessive, but now, this phenomenon seems to have been completed - After much deliberation, I would be placed inside the conductor of the telephone line is there are ways to activate the battery. So the Big Nine in, plug-load line. “Black!” Big Nine automatically stopped and refused to load. Moment of a phantom heart sighs. Fortunately, there is no fee to take a nine short years. (actually the real reason is that nine small phone messages are a lot of great nine are currently facing me as a game), so the evening because it was really late, and stir for a long period without Gao Ding, and is I dare not use that piece of the fast charge to charge a dead battery again.

This morning, a ghost continues to take this piece of rechargeable VGP-BPS10 batteries overmix.

Website for a moment of excessive discharge of lithium batteries to the approach here, but the method does not overload. Indeed, aware of Lithium battery life is very long, but in the excessive discharge through normal use after return to active status after a few, so I think for a moment, since the excessive discharge may be restored, why not over-charging?

Note that the piece of board, regardless of who I spend a couple of times have been maintained at about 3% of electricity (the Big 9 members) must know that the great new, all came to a consumption of small power of nine large, so they are very frequent switching machine If a number of electricity will be consumed, so the 3% of electricity is consumed, it shows that the Dell Inspiron 1300 battery still has power. So, simply put a piece of ghost cells appearing on the Big Nine inside, play with the big 9.

Size of the nine power plays, essentially playing the game, then one day be able to put solar panels are consumed, for a ghost is seen with the use of electricity can be the means crazy for this piece of overcharging return to normal power supply (according to my knowledge in physics, this approach should be feasible). The whole process took about five hours, a ghost has ever been stuck in the game page, if not playing games, there is no exit. During boot, at the prompt once the power is low, see charge of 3%. 13:00, when you are prompted more than once power is low, see the power of 2%. After electricity was View all 2%. Over three hours of the afternoon when the power has created a low-power, or about 2%.

A ghost does not shut down, remove the battery directly. And then re-load, turn, reassuring the phenomenon, and the battery icon prompts full frame, view the power consumption is probably about 91%. Preliminary estimates slightly, depending upon the extent that I played the game, usually consumed at least 10 ~ 15% of electricity, which is, I finally managed to get my panels back to normal.

Xie is really a feeling of days. Therefore, the lithium is still very valuable, and be careful love.

By the way saw a long interview of the lithium battery term means: If you do not use lithium batteries for long term storage, the best discharge to 50%, and probably can be stored for one year. Up to one year, first ~ to ensure that the battery charge and discharge function was normal.

Power Battery room temperature requirements

Power plants, DC position control system power, signal, protection and breaker points, closing and other energy sources, is also the provision of automatic devices, lighting d urgency, such as power. DC system running safe, reliable, all electrical equipment is an important guarantee for the normal operation of the DC system failure or unreliable may lead to downtime, equipment damage and disconnection, even supply system such as accidents. The DC system is usually powered by a rechargeable screen, load DC-fed screen, the composition of the Laptop battery. Battery backup power as a DC system, where the city power failure or accidental power outage, plays an extremely important role. According to the procedures of the State Grid Corporation DL/T724-2000 and 18 major power struggle against the gate-crash measures, battery testing and regular maintenance can prolong and improve the performance and battery life, so to ensure system security. Affect the battery capacity and the performance degradation of the main reasons:

1. Using the environmental impact of temperature on the battery. The existing plant, the vast majority of Power Supply Bureau for the use of VRLA batteries, the operating temperature is 25 ℃, due to its sealed structure, its internal heat dissipation is difficult. Is increased by 10 ℃, the battery life is reduced by 1 / 2. We must be careful when the battery installed, each battery to keep at least 1 cm between the spacing, so that is conducive to the breakdown.

2. The impact on the battery lead-acid batteries VRLA worked in a floating state, the float voltage choosing to capture a significant impact on Dell Inspiron 1100 battery life. Float voltage is selected and the battery temperature rises above or, if there is no time to float adjusted downward tension, it will cause the accelerating loss of battery overload of water, d ‘ where a decrease in battery capacity. Are charging the battery when the charging voltage is too high or the temperature is too high causes the battery internal temperature of the fluid, due to valve structure sealed battery, the heat is not easy to exclude and therefore Also on “thermal runaway” phenomenon to occur, reduce the capacity of the battery.

3. During the impact of discharge on the batteries to discharge the battery also has strict requirements, the battery can not discharge the load below the provisions of the tension of the termination, if less than this value will produce an excessive discharge of the battery, causing the decrease of active ingredients of the hp PB991A batteryaffects their performance and service life, but also difficult to repair.

4. Output devices for the quality of charging batteries affect the current use of large-scale VRLA batteries is different from that of lead acid batteries or nickel-cadmium batteries, its internal resistance is smaller, the output of load performance of the device requires. Conducted in parallel with the battery charging equipment, the ripple coefficient of a larger battery will cause a long period of the load pulse, the discharge state, which accelerates the aging process affects the battery the battery life at the same time, through the use of VRLA batteries depleted solution or less liquid structure, one-off charge or excessive discharge, which may have serious damage to the batteries, the emergence of a new battery load equipment in the regulation of accuracy, automation, reliability and so make new applications. Therefore, the charging device directly affects the battery performance good or bad and the good functioning of the whole system CD. The special structure of the battery, and more leaks, drum kits can be judged from the appearance of the performance is good or bad, if the only criterion for measuring performance across the discharge test, test its actual capacity. On a regular basis to detect and maintain the batteries can accurately understand its performance and prolong its life, thus making the latter to protect DC system.

The maintenance of the battery: 1. On a regular basis to clean the surface of the battery temperature, battery test room, preferably maintained at about 25 ℃. Check the battery terminals and connections online whether fever in bulk, and other phenomena, that the injury or the drum shell package, leaks and so on. 2. On a regular basis to measure and record the total voltage system battery float voltage and current single, they have severely overcharging or less filling phenomenon. 3. Detection of DC output responsible for the quality of the screen, including regulation, constant flow, ripple, and other parameters so as to avoid floating state of the drive long-term damage to the battery. 4. On a regular basis to perform maintenance of the battery charge and discharge, which can lead to a result of long-lasting battery variable active substance activity decreased activation play a role. 5. On a regular basis to check if the battery discharge test with constant current, testing the capacity of the sony VGP-BPS2 battery, the battery capacity and thereby achieve “a pretty good idea” to ensure that electrical accidents in the city without power, control, signaling, protection and breaker points, fencing, etc. to provide sufficient electrical energy to increase the power of unexpected power loss to a minimum.
