Fujitsu LIFEBOOK T4220 Battery
Your Fujitsu LIFEBOOK T4220 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 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. Not all batteries are the same, make sure and double-check the part number of the new battery and compare it to the old battery. The more power the battery has, the longer it will last on a single charge.
Key symptoms of a defective battery
- The battery gets puffy and looking like it is going to burst
- The unit will not turn on while not connected to the AC adapter
- The laptop lasts under 20 minutes before it shuts itself down
