72wh 61++ 01AV427 01AV425 T480 T470 Laptop Battery for Lenovo Thinkpad A485 T580 P51S A475 TP25 T570 P52S Series SB10K97584 SB10K97579 SB10K97585 SB10K97580 4X50M08812 X50M08812 01AV490 01AV422 11.1V

Bought this to refurbish a new-to-me Thinkpad T470. It's an extended battery so it has a bump on the bottom to raise it off the table for added airflow, and I like that. However, others may not, so it's good to know this battery won't let your laptop sit flat. Other than that, it fit great, slid right into the bay and locked in, my OS immediately recognized it and began charging it. So far, it has kept charge and seems to have good battery life. Good value to keep this T470 going.

Battery life is no where close to the original battery. Laptop is set to charge to 80% as recommended

Very happy with my purchase.

It's a ok battery, but it is not a 72Wh battery, so I have to take a star off for that. It's *supposed* to be a 64.8 watt hour battery, but the one I got is actually only a 59.4Wh, which is significant.

Fits my T480 fine. I charged it up and have been using it for over two hours with no problems. Solid build. Does not get hot. Seen by the OS and all systems are go. Perfect to replace the battery in your T470 or T480. Good price, too.
