Lenovo Compatible Battery 6 Cell 48 Wh 61+

This compatible Lenovo battery is intended as a replacement for the 01AV425 reference, also identified with the 61+ designation. The Lenovo parts listing describes 01AV425 as the CT470 external battery with six cells, 48 Wh capacity and lithium-ion technology. The documented replacement configuration provides 10.8 V and 4400 mAh, with a stored energy capacity of 48 Wh. These specifications define the electrical characteristics of the six-cell battery and distinguish it from other battery capacities available for related notebook platforms. The replacement reference list also includes 4X50M08811, SB10K97582, 01AV491, SB10K97583 and 01AV426. Compatibility is documented for Lenovo A475, A485, ThinkPad 25, T470, T480, T570 and T580 notebooks. This battery is therefore suited to restoring the external battery function of compatible Lenovo notebook configurations that use the 01AV425 or 61+ battery reference. It is a compatible replacement product and is not presented as a Lenovo-manufactured replacement.
