Lenovo ThinkPad R31 Battery
Your Lenovo ThinkPad R31 battery makes your laptop portable so as to work or play inside, outside or anywhere your heart desires. Buying a battery with a higher milliamp rating is fine, it just means the battery will go further on a single charge. What is truly important is the actual size of the battery and the connection it has. Because no battery is the same, make sure and double-check the model number and compare it to the one you are going to replace. The larger the battery, the longer it will last when fully charged.
Elements of a deteriorating primary battery
- The laptop will not turn on while unplugged
- The battery gets puffy and looking like it is going to burst
- The laptop lasts way less than it used to before it dies
