Compaq Presario 1800 Battery
Your Compaq Presario 1800 battery makes your laptop portable so as to work or play anywhere you please. The more power the battery has, the longer it will last on a single charge. Because no battery is the same, be sure to check the part number of the new battery and compare it to the old battery. Buying a battery with a higher milliamp rating is fine, it simply means it is a stronger battery. What really is critical to a battery fitting your laptop is the actual size of the battery and the connection it has.
What are the clues to watch out for to know my battery is about to stop working?
- The laptop does not turn on while not connected to the AC adapter
- The battery has its case swollen and looking like it is going to burst
- The laptop does not last longer than 45 minutes while using the battery only
