Lithium-ion battery has the following advantages, such as:
1. Long life cycles may reach 500 times more than 1000 times
2. Security
3. Performance is good, pollution-free, no memory effect ion - in the past.
4. Self-discharge
5. Can be quick recharging
6. Working temperature range, high temperature - 25 ~ 45 ° C, electrolyte and positive, it expects to expand Improvement - 40 ~ 70 ° C.
Future of lifepo4 / positive applied to electric cars can charge such as gas, interim general convenience.
At the same time pack of lithium-ion batteries are also some disadvantages, such as:
1.
2. High ambient temperature can cause the battery to overheat, fire and other safety hazards.
It is reported that the 20th May 2005 Hewlett-Packard announced that it will extend laptop battery recall program in global reach. The six paragraphs 6 notebook with lithium battery products that belong to HP Compaq series to be recalled. The models, the HP 6510b, HP 6515b, HP 6710b, HP 6710s, HP 6715s, HP 6715s. so this type of lithium-ion batteries were manufactured in 2007 and 2008. But some of those defective lithium-ion batteries less than 3%.
It is a big problem that how to protect battery and prolong its life. People always used many misconceptions, such as:
Error 1: laptops to buy back again to activate the battery is charging and discharging three times
Error 2: the first charge should be charged enough for 12 hours
Error 3: The battery must be periodically correction once a month was totally
Error 4: The calibration error can climb battery capacity
Error 5: compatible charger can also use
Error 6: full battery-electric (or need) to save electric light
Error 7: battery and errors can still change the fundamental
Error 8: 99% misconception remains less than 100% charged rechargeable would explode.
Here we provide you with the protection of laptop battery and precautions.
About laptop batteries warns:
1. During charging, do not pull down power converter.
2. Do not use this machine on battery.
3. If you use a laptop computer is first, or you long time no one uses it (three weeks or longer) must be completely filled with electricity after discharge battery full power to recover.
4. Whether the batteries in the computer self-discharge phenomenon (day, depending on the different models around 1% a little different).
5. If the computer for a long time without use (more than three weeks), suggests that you pull a battery, battery separately store.
6. For lithium ion batteries, environmental damage will also have some risk. Please do not discard.
7. if the battery can take a long time but has no electricity (battery to prevent over-discharge battery, battery cause damage), how much depending on the length of time accumulator, which for a long time, the battery is some more of the rechargeable battery in power is to prevent the long time storage cause excessive emissions.
Notebook batteries used for more than a year that it is necessary to remove memory effects:
1. Computer is connected to the remote switch, fees and charges for 6 ~ 8 hours.
2. The full charge later. When the screen "Press F2 for setup, press F2] [enter the BIOS setup program and let it stop computers.
3. Unplug the power supply must constantly open up the computer racks and closures.
4. Connected to the power supply to batteries.
5.
6. Above steps again and again 2-3 times, removing a portion extend battery memory effects.
