Dell Inspiron 1721 Battery
Your Dell Inspiron 1721 battery allows you to move freely about which gives you the opportunity to use it anywhere you please. More amps in a battery basically means the longer you will be able to use the laptop when fully charged. Getting a battery with a higher amp rating is OK, as it signifies that the battery can last for a longer period of time on one charge. What really is critical to a battery fitting your laptop is the connection type and physical size of the battery. Not all batteries are the same, make sure and double-check the model number and compare it to the old one.
How do you know when your battery is not working properly?
- The unit is unable to boot up while unplugged
- The laptop lasts less than half an hour while using the battery only
- The battery has its case swollen and looking like it is going to burst
