Dell Inspiron 17R-7720 Battery
Your Dell Inspiron 17R-7720 battery makes your laptop portable so as to work or play anywhere in the house or even outdoors! The larger the battery, the longer you will be able to use the laptop on a single charge. Buying a battery with a higher milliamp rating is fine, as it signifies that the battery can last for a longer period of time on one charge. What is truly important is the connection type and physical size of the battery. Not all batteries are the same, be sure to check the size and model number in order to make sure it is similar to the one you are going to replace.
What warnings are present when my battery is about to stop working?
- The unit is unable to boot up when not connected to the charger
- The battery is puffed up and looking like it is going to burst
- The laptop does not run longer than one hour before it shuts itself down
