Lenovo ThinkPad R51 Battery
Your Lenovo ThinkPad R51 battery allows you to move freely about which gives you the opportunity to use it where you want. It is OK to buy a battery with more milliamps, as it signifies that the battery can last for a longer period of time on one charge. What really is critical to a battery fitting your laptop is the connection type and physical size of the battery. 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. The more power the battery has, the longer you will be able to use the laptop on a single charge.
Hints your battery has little time left
- 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 less than half an hour while using the battery only
