Acer Aspire 1640 Battery
Your Acer Aspire 1640 battery makes your laptop portable so as to work or play anywhere you please. Getting a battery with a higher amp rating is OK, 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. 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.
Subtle cues of a faulty primary battery
- The laptop lasts way less than it used to before it dies
- The laptop battery has its case swollen like its about to burst
- The unit does not turn on at all when unplugged
