What is the power capacity of the Dell CF711?
The Dell M65 battery (CF711) is rated at 85 WHr (Watt Hours) or 7800 mAh (mili-Amp Hours). This extra capacity enables you to work longer while you are away from an electrical outlet.

The larger the capacity specification, the more energy (fuel) you will be able to store and use.
What are the advantages of a Lithium ion battery?
Lithium ion batteries represent the state-of-the-art in battery technology. Li–ion cells are now the most widely used batteries in laptop computers, camcorders, cell phones, and most portable electronic devices. Computer manufacturers know that they can rely on Lithium technology to provide reliable and safe power. Lithium is one of the lightest metals known and has great electrochemical potential. Lithium ion's light weight and chemical properties make an ideal combination and give it one of the best energy–to–weight ratios of any battery compound. Unlike other chemistries, Lithium ion is a low maintenance battery with a relatively low self–discharge rate (slow loss of charge when not in use). Memory and scheduled cycling are not mandatory to extend the battery's life compared to older technologies. Li–ion batteries do not require replacements often, as they are long lasting.
What is the normal useful life of a Dell CF711 Battery Pack?
Most users get between 2 to 3 years of service from their Dell CF-711 Laptop Battery before needing to replace it. Of course, this lifespan depends on individual patterns of usage. Basically, the more you run your laptop on the battery (not on AC Power) the faster you will need to replace it.
But I thought all CF-711 batteries were rechargeable. So why do they wear out?
Of course the Dell CF711 battery is in fact a rechargeable battery pack. But unfortunately, we still have not yet invented "the perfect battery," and since there is no such thing as a perpetual motion machine, the Dell CF711 will eventually need to be replaced. You see, each time you charge and discharge the Dell Computer CF-711 battery, a chemical reaction occurs inside the battery cells to store or release the electricity you need to power your notebook. Part of that chemical reaction uses up a tiny portion of the Lithium Ion chemistry in your CF711 battery pack. Eventually those chemicals are depleted and once that happens, your battery will not hold a charge. Individuals will begin to notice a gradual drop off in the performance of most laptop batteries after approximately one year of normal usage.
