Replacement Battery for ThinkPad T470 Series

This 10.8V 48Wh lithium-ion unit replaces Lenovo part numbers including 01AV425 and SB10K97582 across ThinkPad T470, T570, T480, T580, A475, A485, P51S, P52S and TP25 models. It is a new component rated at 4400mAh capacity.

Capacity and Voltage Limits

The pack delivers 48Wh at 10.8V using lithium-ion chemistry with a stated high recycle life and energy density. Runtime depends on the specific laptop workload and power management settings. It will not suit systems that require a different voltage or physical form factor.

Installation and Common Issues

The battery fits the internal bay of the listed ThinkPad models without tools. Alignment of the connector is the main point of failure; forcing it can damage the motherboard header. Buyers who need a higher-capacity pack or a different connector layout should look elsewhere.

Questions about this item

Should I choose the 61++ 48 Wh version or the standard 61+ model for my ThinkPad T480?

The 61++ label on this battery means it delivers the full 48 Wh capacity, giving longer runtime than the standard 61+ packs that often sit around 44 Wh.

What does the 48 Wh rating actually give me in daily use on a T580?

A 48 Wh pack typically powers a ThinkPad T580 for roughly 6 to 9 hours of mixed office work, depending on screen brightness and background tasks.

Does the 10.8 V output match the original Lenovo 01AV426 specification?

Yes, the 10.8 V output and 4400 mAh capacity match the 01AV426 part number, so the battery fits and charges correctly in the listed ThinkPad models.
