Lenovo Ultrabay III Notebook Battery (57Y4536)




Genuine Lenovo ThinkPad Ultrabay III Notebook Battery

Delivers the power of a second battery, but you do not have to carry around a spare loose battery.

Offers similar specifications to the standard system battery - Use it in the Ultrabay of the ThinkPad system along with your standard system battery to get up to twice the unplugged usage time as you could get with the standard system battery alone. Since the battery works in the Ultrabay you don't have to suspend the system to swap out the system battery to use the ThinkPad for an extended period of time.
