What this battery replaces

This 3-cell lithium-ion unit replaces the Lenovo ThinkPad 61 battery (part 01AV423) and is also compatible with the higher-capacity 61+ and 61++ packs. It fits ThinkPad T470, T480, T570, T580, P51S, P52S, A475, A485 and TP25 models. Buyers needing 48 Wh or 72 Wh capacity should look elsewhere.

Sustained discharge behaviour

Rated at 11.4 V and 24 Wh (2100 mAh), the pack delivers a steady voltage through typical office workloads. Overcharge, overdischarge, over-temperature and short-circuit protection circuits maintain stable output during long sessions. It is not designed for extended heavy-load use without mains power.

Thermals, noise and power draw

The battery operates silently and adds no active cooling requirement. Normal charging follows the laptop’s built-in controller at 10.8 V / 11.4 V with low power consumption. CE, FCC and RoHS certifications confirm compliance with safety and environmental standards.

Questions about this item

Does the 24Wh 3-cell battery run hotter than the original 48Wh pack during all-day use?

The 24Wh capacity is half the 48Wh design, so each cell handles more current; expect warmer operation under sustained load.

Will this 01AV423 replacement work without the original Lenovo charger?

It charges from any 10.8V / 11.4V ThinkPad AC adapter that fits the T470, T480, T570, T580, P51S or P52S barrel or USB-C port.

Can I keep my 61++ 72Wh battery installed and swap only the internal 3-cell pack?

The 01AV423 replaces the entire 61, 61+ or 61++ pack; it is not a cell-level module for the larger 72Wh housing.
