Dell Inspiron 17R 3721 Battery
Your Dell Inspiron 17R 3721 battery allows you to move freely about so as to work or play anywhere in the house or even outdoors! More amps in a battery basically means the longer it will last when fully charged. It is OK to buy a battery with more milliamps, as it signifies that the battery can last for a longer period of time on one charge. What is important is the physical size of the battery as well as the connection. Not all batteries are the same, be sure to check the part number of the new battery and compare it to the old battery.
What symptoms are present when the li-ion battery is almost going bad?
- The laptop lasts less than half an hour before it shuts itself down
