Sony VGN-AR750E Battery
Your Sony VGN-AR750E battery makes your laptop portable which gives you the opportunity to use it where you want. Buying a battery with a higher milliamp rating is fine, because it simply implies that the battery will last longer. What is important is the connection type and physical size of the battery. 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 size and model number in order to make sure it is similar to the one you are going to replace.
Red flags of a worsening primary battery
- The unit is unable to boot up at all when unplugged
- The battery gets puffy and looking like it is going to burst
- The laptop lasts way less than it used to while using the battery only
