As a bonus, the Sonata battery can be charged to 80 percent capacity in about 30 minutes. Conventional notebook batteries take one to two hours to get to 90 percent capacity.

“We picked 30 minutes and drove development to that,” Lampe-Onnerud said.

The company is part of a wave of battery start-ups that have emerged in the past few years. Most got started initially to improve the runtime on notebooks or power tools. A raft of explosions and recalls, however, have also pushed safety to the forefront.

The popularity of hybrid and electric cars has also juiced the market. Last week, A123 Systems, which makes lithium ion batteries(gd761,kd476) for plug-in hybrid cars, announced it had raised $40 million more in venture capital funds.

Boston-Power has been one of the more noteworthy new entrants in part because the somewhat secretive company, which came out of semi-stealth mode late last year, employs many scientists and executives, like Lampe-Onnerud, who have worked in the battery industry for years. Along with showing off the battery publicly for the first time this week, Boston-Power also announced it closed a second round of funding for $15.6 million.

There is no magic silver bullet inside the Sonata, Lampe-Onnerud said. Instead, the battery differs from conventional notebook batteries through a large number of design tweaks.

“We understand the system. We don’t have a killer chemical,” she said.

The can, or outside casing around the battery cells,inspiron b120 battery,inspiron b130 battery, is made from a metal alloy that is stronger than the iron cans used with notebook batteries and thus will remain intact, in the case of a thermal reaction, or fire, according to the company.

Boston-Power also spent a lot of time on the interrupt system, which prompts the battery to shut down permanently if there is danger of a reaction. (Replacements are covered by a three-year warranty, which Lampe-Onnerud says is longer than the industry average.) The company can’t guarantee the batteries will never have problems, but it has added safety features not seen in ordinary batteries.

“If it is really damaged, I don’t want it to work again,” she said.

At the same time, the battery generally meets the performance characteristics of conventional batteries(latitude d600 battery) on the market today.

HP is likely the first customer, according to Lampe-Onnerud. A contract to put the battery inside a notebook has yet to be signed, but it’s possible a notebook with a Boston-Power battery could hit the market by summer, she said. John Wozniak, an HP distinguished technologist, will appear with Lampe-Onnerud during the Demo presentation.

An HP representative said the company has been testing the batteries and is pleased with the results, pavilion dv6000 battery is better ,but added that further testing will occur. A notebook containing the batteries potentially could come out this year, the representative added, but nothing has been signed and, again, further testing will occur.

Typically, large manufacturers move slowly and conservatively when adopting new components, and then introduce them on a limited basis.

The Sonata will sell for a premium, but Lampe-Onnerud would not disclose details on pricing.

The big challenge facing Boston-Power now is whether it can move into high-volume manufacturing. The company already has an alliance with a large Chinese contract manufacturer.

While Lampe-Onnerud was somewhat tight-lipped about how Boston-Power’s product differs from conventional batteries, a patent search indicates that one change will involve altering the chemistry of the cathode. Currently, cathodes are made from lithium cobalt compounds. The July 2005 patent, suggests swapping that out for lithium nickel materials.latitude d830 battery,latitude d500 battery.

More information can be found under a second patent from February 2005. Although a company’s patents can lead to future products, there is no guarantee that a correlation exists, and Boston-Power has several pending, unpublished patents.

Step 2If you don’t want to buy a better battery than you can make some changes to your settings on your laptop that will increase the battery life.

Step 3This is for Vista users

Click on start/control panel/Mobile Pc/Power Options.

Here you can select how much power you want to save but the more power you save the slower your pc becomes. (Note)that if you change the settings to power save or balanced then when your laptop is plugged into a power outlet, your laptop will still be set to a slower performance.

Step 4: Click on High Performance and click on Change Plan Settings. This is the best setting because you can fully customize how much power you can save while running of your laptop but when you plug into a power outlet your laptop will return to the High Performance Setting.

Step 5: When the High Performance Setting window pops up then click on Change Advance Power Setting and then the Power Option window will popup.

Step 6:Power Option Settings:

Here you have full control over your battery settings.

Click and expand the Hard Disk tab.

Turn off hard disk after: On inspiron E1505 battery: You can set this to the desire time that you want. I have mine set to 30min//Plugged in: Again, you can set this to the desire time that you want. I have mine set to Never because plugged in I am not using my battery.

Step 7: Expand the wireless Adapter Settings:

Power Saving Mode:

On battery: Here you can select Maximum Performance or Maximum Power Saving. If you want your internet to still be fast then select Maximum Performance but if you want to save dell E1505 battery power and don’t mind a slower internet then select Maximum Power Saving. There are two more settings that you can select to have it a Medium Power Saving and Performance.

Plugged in: You will want this to stay on Maximum Performance.

Step 8: Expand the Sleep tab:

Sleep After:

On battery: Select the time which you want it to go into sleep mode while running on the battery. I have mine set to 15min

Plugged in: I have mine set to Never

Step 9: Expand the Processor Power Management tab:

Minimum processor state.

This is how fast your laptop will be when plugged in or running on the battery

On battery: Set it to 15%

Plugged in: set it to 100%

Now expand the Maximum processor state:

On battery: you can choose 20% to save on battery but if you need more speed when running the GD761 battery you will need to increase this number to around 50%

Plugged in: Set this to 100%

Step 10: Expand the Search and Indexing tab:

Power Saving Mode:

On battery: Set it to Power Saver

Plugged in: Set it to High Performance

Step 11: Expand the Display tab:

Turn off display after:

On battery: set it to 5min

Plugged in: you can set it to whatever you want. I have mine set to 20min

These setting will turn off your screen after the given time that you set.

Step 12: When you are done click on Apply at the bottom and then on OK

Step 13: You will be back to the Change Settings for the plan: High Performance window. On this page you can adjust the display brightness:

On battery: slide the bar to the left and it will dim the screen when it is running on the battery.

Plugged in: You can just leave the slide bar all the way to the right.

If you do not change the display brightness then your graphic card software will be monitoring it and you will need to launch the program to make the changes.

Step 14: When you are done click on Save Changes at the bottom and close out all open windows.

Step 15: Un-plug your power adapter and move your mouse toward the time in the right lower side of your screen at the taskbar and place your mouse cursor over the power option icon and it will display the life of the xps m1330 battery. Ignore the warning about your current plan may reduce battery life because you made the advance changes to your battery. With these new changes on my laptop with a 6 cell battery I am now getting 4 1/2 hours of battery life. Before I was only getting 2 hours of battery life. But this is only with my laptop yours may be different.

Step 16 : Also, the more programs that you run while using the battery will drain it faster so try not to run a lot of programs.

Step 17: Xp users

Click start/control panel and navigate to your power options.

Now I don’t have windows xp anymore but if you look around on all the tabs and look for advance options then you will be able to adjust the battery life to what you want it to.

Step 18: If you are not happy with the performance of your laptop with saving more laptop batteries life then go back and increase the processor number.
