Sony VGN-CR115E Battery
Your Sony VGN-CR115E battery makes your laptop portable so as to work or play anywhere you please. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer on one charge. What is truly important is the connection type and physical size of the battery. Because no battery is the same, make sure and double-check the model number and compare it to the one you are going to replace. More amps in a battery basically means the longer it will last when fully charged.
What warnings should I watch out for to know if my Sony battery has gone bad?
- The battery gets puffy like its about to burst
- The Sony laptop does not turn on while unplugged
- The laptop lasts under 20 minutes while using the battery only
