Need more running time for your Dell notebook computers ?
Can not find a battery for your Dell notebook computers ?
This External Lithium Rechargeable Battery Pack is the Solution for You !
Here is the partial compatibility list:
Tech Note:The battery works like a AC power adapter to a laptop. Some Dell laptop BIOS has a special setting: if it detects a non Dell AC power adapter, it will give warning message or refuse to work even the battery will work perfectly with it. You can ignore the message or just disable the warning setting in the BIOS and the battery will work perfectly.
How this battery works:
1. This battery has it own battery charger, you can charge it from any 110V or 220V AC power source with the included AC charger.
2. After the battery has been fully charged, set the voltage output of the battery close to your notebook DC power input requirement (which is same as your notebook AC power adapter's DC output voltage).
This battery has a switch to set the voltage output at 16V or 19V. 16V is compatible with 15V~16.5V, 19V is compatible with 18V~21V.
3. Select the right connector tip:
Included with the battery pack are 8 regular round shape connector tips that work with most notebooks + 2 special connectors for some Dell laptops.
8 round shape connectors.
+
2 special Dell connectors.
With the plug tip not connected to the adapter cord, locate the correct tip by fitting the tip into the notebook DC Jack. The tip should fit snugly in the DC jack.
4. Set Polarity & Plug the tip
After you have selected the proper plug tip, you need to connect the plug tip to the adapter cord to match the correct polarity setting. It is CRITICAL that you determine and set the correct polarity needed for your product before using the adapter. FAILURE TO DO SO MAY RESULT IN SEVERE DAMAGE TO YOUR PRODUCT!
To determine the correct polarity for your product, inspect the DC adapter jack or the label of your product thoroughly for information about the products polarity. There will be a symbol with a plus sign on one side and a minus sign on the other with a circle between them. The circle will have an opening so that it looks like a "C". If the opening of the circle is on the side with the plus sign the polarity is positive. If the opening is on the side with minus sign the polarity is negative. If you cannot find a polarity sign on your product you need to call the product's manufacturer to find out what the polarity is.
There is a small plus (+) and minus (-)sign on the plastic part of the plug tip above the two pins where you plug the tip into the cord. On the adapter's cord where you connect the plug tip - you should notice the word "tip".
If your polarity setting is POSITIVE, you need to set the plug tip to "tip positive" by connecting the "plus sign" and the word "tip" on the adapter cord so they line up on the same side. Most laptops polarity setting is Positive like bellow picture:
Most laptops need positive polarity.
If your polarity setting is NEGATIVE, you need tip to set the plug tip to "tip-negative" by connecting the "minus sign" and the word "tip" on the adapter cord so they line up on the same side.
After you have selected the proper plug tip, connect the plug tip to the battery cord.
5. Turn on the battery and Connect the External Battery Pack to your notebook DC power input jack (which is the same jack your notebook AC power adapter usually plugs into). Now you can power your notebook from this External Battery Pack .
CAUTION: Always turn off the battery when you do not use the battery. The Test button is also an on/off switch. To turn on the battery, please press “Test” button and hold it for about 10 seconds, the Red LED will light up. To turn off the battery, just press “Test” button and hold it for about another 10 seconds and the Red LED will be off. Leave the battery “on” may build up static inside the battery cells and damage the battery. The Red LED will keep on when the battery is on, the Red LDE will be off when the battery is off.
How long can this external battery run ?
Actual running time may vary, depending on notebook computer's configurations and what kind of applications running . This battery's capacity is 111Wh(Watt-hour):
you can compare this battery's capacity with your internal battery capacity to figure out how long this battery can run your notebook. For example, if your notebook internal battery out put is: 10.8V & 4000 mAh
Then, your notebook internal battery capacity is
10.8V x 4000 mAh = 43200 mVAh= 43.2 Wh (Watt-hour).
If a brand new fully charged internal notebook battery can run 3 hours, then the PM-111 external battery pack can theoretically run about : 118Wh/43.2Wh x 3 hours = 8.2hours. Again, this is a rough estimate. Actual running time varies, depending on notebook computer's configurations and what kind of applications running . For example, screen brightness, the use of the CPU, the hard drive, the CD drive, and other peripherals results in an additional drain upon the battery, effectively reducing the battery's run-time. The total run-time of the battery is also heavily dependent upon the design of the notebook. To ensure maximum performance of the battery, optimize the computer's power management features. Refer to the computer manual for further instructions.
