Extended laptop batteries are specifically designed for each laptop model and have additional cells in the battery pack which allow the batteries to run longer between charges. Most laptops come equipped with a standard size battery pack that will last 2 to 2-1/2 hours when new. Extended batteries can provide additional run times from 30% to 300% longer. Notebook battery capacity is measured in mAh ratings. You will find your mAh rating printed on your battery pack. If your existing battery has 4400 mAh capacity and the extended battery is listed at 8800 mAh, you will enjoy twice the battery run time and up to 5-6 hours of run time with an extended battery! All our extended run batteries will include the mAh rating on the battery pack and in the online description.

When it's time to replace your battery, an extended battery is often a good choice if longer battery run times will allow you the added freedom away from wall outlets.

Extended laptop batteries are not for everyone. Extended batteries tend to be physically larger and heavier than their regular counterparts. This is due to the additional number of cells an extended battery contains. For most laptops, the extended battery packs will protrude to the rear or bottom of the laptop. You will want to consider the dimensions of your carry case and the added weight of extended battery packs. Extended batteries usually add about 6 - 12 ounces of additional weight. Unfortunately, not every laptop model has an extended battery pack available. If there is an extended version available it will show up in your laptop model search results on our website.

To find the extended battery for your particular laptop, simply select Manufacturer from the drop down box below, then click the Go button to ensure all replacement notebook batteries are listed in alphabetical order by laptop manufacturer. Once you get to your manufacturer's extended batteries, look for your laptop model number. Then, click on the appropriate photo for more details and to purchase.

If you don't see the laptop model number you need, it may mean an extended replacement battery does not exist for your particular laoptop. In that case, give us a call...we may still be able to help.
