Samsung R21 Battery
Your Samsung R21 battery makes your laptop portable so that you can use it anywhere in the house or even outdoors! More amps in a battery basically means the longer it will last on a single charge. Because no battery is the same, be sure to check the model number and compare it to the one you are going to replace. Buying a battery with a higher milliamp rating is fine, as it suggests the battery will last a bit longer on one charge. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection.
Some clues of a weakening Samsung battery
- The laptop battery is puffed up and looking like it is going to burst
- The laptop does not last longer than 45 minutes before it shuts itself down
- The unit refuses to turn on while not connected to the AC adapter
