This is a brand new Extended Run Dell replacement battery. This long run battery will run at least 50% longer than the standard capacity battery that ships standard with your laptop. The added run time is achieved with an additional 3 cells inside the cartridge. The extended run battery is our best-selling model as the added capacity does not require a larger battery pack. The extended run battery pack is the same size battery cartridge as the original 6 cell battery. Users of this battery pack experience an additional 1-2 hours of run time over the standard battery for just $10.00 added cost.
Estimated run time with this battery is 3-5 hours. Longer run times can be achieved by minimizing the power use, especially the screen brightness.
The superior South Korean cells inside the battery cartridge will provide longer run times between charges as well as a longer service life than cheaper batteries. In addition, Li-ion batteries are not subject to the memory effect common with older battery technology. This means you can recharge your laptop any time without diminishing your battery capacity. This laptop battery replacement is typically superior to the original battery and is 100% compatible with your Dell laptop computer. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.
Not all computer batteries have the same capacity and run times. The higher capacity battery cells inside this cartridge have an energy capacity of 6600 mAh.
This battery replaces the Dell Latitude D810 and Precision M70 series laptop batteries and additional machines which are listed at the extreme bottom of this web page.
