Acer Aspire 5742G Battery
Your Acer Aspire 5742G battery makes your laptop portable so that you can use it where you want. Getting a battery with a higher amp rating is OK, as it just means the battery will last longer. What is important is the connection type and physical size of the battery. The larger the battery, the longer it will last when fully charged. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old one.
Chief elements of a weak primary battery
- The laptop lasts under 20 minutes before it dies
- The unit will not boot up while not connected to the AC adapter
- The laptop battery has its case swollen and looking like it is going to burst
