Battery Talk

There are two ways to squeeze extra Toshiba PA3191U-4BRS battery life out of a computer. You can reduce power consumption, and you can use a ridiculously high capacity battery. It looks like come December, Acer Aspire Timeline users will have the option of taking both approaches.

The Acer Timeline series includes a number of thin and light laptops with screens ranging in size from 11.6 inches to 15.6 inches of Toshiba PA3284U-1BRS. They all use Intel CULV (Consumer Ultra Low Voltage) processors, which offer better-than Atom performance while consuming less power than other Intel or AMD laptop processors.

The Timeline laptops currently ship with 6 cell Toshiba PA3331U-1BRS which can provide between 4 and 8 hours of battery life. But at a recent event in Germany, Acer announced plans to release a 9 cell PA3356U-1BRS battery in December. NewGadget.de reports that it should provide up to 12 hours of run time for some Aspire Timeline models.

There’s no word on pricing, and it’s not clear whether the PA3384U-1BRS will come standard with some Timeline computers or if it will be available as an optional accessory. On the one hand, it will certainly add some weight to these thin and light notebooks. On the other hand, a 12 hour battery would be pretty awesome.

It occurs many times when you need your laptop battery power the most, like when you are giving a presentation or doing some important work but battery goes down and reaches a critical battery level.

Specially with windows vista powered  Apple laptop Battery  this situation occurs more often, as the Graphic User Interface in vista like Aero, Vista sidebar etc. consumes much more battery power.

But you can make better and efficient usage of your battery using an application called Vista Battery Saver which will save 70% of the battery power in vista by disabling these nice looking features Aero and Vista Sidebar.

Let’s see what more features it can offer

It will also allow you to temporary disable the notification messages when Windows Aero Or Windows Sidebar is activated / deactivated Inspiron B130 Battery, Inspiron E1405 Battery.

Lithium-ion Battery Life and Death

Lithium-ion laptop battery packs are expensive, so if you want to make yours to last longer, here are some things to keep in mind:

• Lithium ion chemistry Sony pcga bp71 prefers partial discharge to deep discharge, so it’s best to avoid taking the battery all the way down to zero. Since lithium-ion chemistry does not have a “memory”, you do not harm the battery pack with a partial discharge. If the voltage of a lithium-ion cell drops below a certain level, it’s ruined.
• Lithium-ion batteries age as Dell inspiron 6000 battery. They only last two to three years, even if they are sitting on a shelf unused. So do not “avoid using” the battery with the thought that the battery pack will last five years. It won’t. Also, if you are buying a new battery pack, you want to make sure it really is new. If it has been sitting on a shelf in the store for a year, it won’t last very long. Manufacturing dates are important.
• Avoid heat, which degrades the Toshiba pa3465u-1brsbatteries.

Exploding Batteries

Now that we know how to keep lithium-ion batteries working longer, let’s look at why they can explode. Several news reports in the past six months describe laptops with lithium-ion laptop battery that caught on fire.

If the Toshiba pa3107u 1brs battery gets hot enough to ignite the electrolyte, you are going to get a fire. There are video clips and photos on the Web that show just how serious these fires can be. The CBC article,”Summer of the Exploding Laptop,” rounds up several of these incidents.

When a fire like this happens, it is usually caused by an internal short in the battery. Recall from the previous section that lithium-ion cells contain a separator sheet that keeps the positive and negative electrodes apart. If that sheet get punctured and the electrodes touch, the battery heats up very quickly. You may have experienced the kind of heat a Toshiba pa3384u 1brs batterycan produce if you have ever put a normal 9-volt battery in your pocket. It a coin shorts across the two terminals, thebattery gets quite hot.

In a separator failure, that same kind of short happens inside the lithium-ion evo n600c battery. Since lithium-ion batteries are so energetic, they get very hot. The heat causes the battery to vent the organic solvent used as an electrolyte, and the heat (or a nearby spark) can light it. Once that happens inside one of the cells, the heat of the fire cascades to the other cells and the whole pack goes up in flames.

It is important to note that fires are very rare. Still, it only takes a couple of fires and a little media coverage to prompt a recall.
