Acer TravelMate 4000M Battery
Your Acer TravelMate 4000M battery makes your laptop portable so as to work or play wherever you fancy. It is OK to buy a battery with more milliamps, 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 connection type and physical size of the battery. More amps in a battery basically means the longer you will be able to use the laptop on one charge. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the one you are going to replace.
What are the signs that the battery is about to stop working?
- The laptop will not turn on when it is not plugged in
- The laptop lasts less than half an hour while unplugged
- The laptop battery is puffed up and looking like it is going to burst
