Compaq Presario 2800 Battery
Your Compaq Presario 2800 battery makes your laptop portable which gives you the opportunity to use it where you want. The larger the battery, the longer it will last when fully charged. 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 one. 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 is truly important is the actual size of the battery and the connection it has.
Important signs the primary battery has very little life left
- The unit will not turn on at all when unplugged
- The battery has its case swollen and looking like it is going to burst
- The laptop lasts under 20 minutes before it dies
