Compaq Presario CQ71 Battery
Your Compaq Presario CQ71 battery allows you to move freely about which gives you the opportunity to use it where you want. Getting a battery with a higher amp rating is OK, it simply means it is a stronger battery. What is truly important is the actual size of the battery and the connection it has. Not all batteries are the same, make sure and double-check the size and model number in order to make sure it is similar to the old battery. More amps in a battery basically means the longer you will be able to use the laptop when fully charged.
Major symptoms of an ineffective primary battery
- The battery is puffed up and looking like it is going to burst
- The unit is unable to boot up while unplugged
- The laptop lasts under 20 minutes while unplugged
