Dell Inspiron 3521 Battery
Your Dell Inspiron 3521 battery allows you to move freely about so that you can use it inside, outside or anywhere your heart desires. The larger the battery, the longer you will be able to use the laptop when fully charged. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old one. It is OK to buy a battery with more milliamps, it just means the battery will go further on a single charge. What is truly important is the connection type and physical size of the battery.
Some clues of a defective li-ion battery
- The laptop lasts under 20 minutes before it shuts itself down
- The unit will not turn on while unplugged
- The battery has its case swollen like its about to burst
