Which Lenovo laptops will this battery work in?

This battery is compatible with many ThinkPad T, P and A series laptops but is not a universal fit. Double-check your laptop’s model or part number before ordering to ensure correct compatibility.

• Compatible models: ThinkPad T570, T580, T470, T480, P51S, P52S, TP25, A475, A485 and some X260 series machines.
• Compatible part numbers: 01AV422, 01AV423, 01AV424, 01AV452, 01AV490, 4X50M08810, SB10K97579, SB10K97580, SB10K97581, SB10K97597.
• Not compatible with: T460s, T470s, T480s series—these slimmer models require different battery profiles.

How long will the battery last and what safety features are included?

The Fancy Buying pack is built to deliver long-term service while protecting the laptop and user through several control measures. It’s engineered for up to 500 recharge cycles and includes multiple protections to reduce risk from common battery faults.

• Capacity: 24Wh at 11.4V with a 3-cell Li-ion layout for consistent voltage output.
• Cycle life: rated for approximately 500 recharges under normal conditions.
• Safety: built-in overcharge, over-discharge, overcurrent, short-circuit and temperature protection circuits.

Will this replace larger capacity packs and how does it compare?

This 24Wh battery is a compact option intended as a like-for-like replacement for the listed part numbers. While there are higher-capacity 48Wh and 72Wh options compatible with some Lenovo models, choosing this pack restores original form factor and power characteristics.

• Form factor: matches the physical size and connector layout of the corresponding 61-series battery.
• Alternate options: compatible with systems that accept 48Wh (01AV425) or 72Wh (4X50M08812) packs, but those are physically larger.
• Performance trade-off: smaller capacity means lighter weight but shorter runtime versus 48Wh/72Wh units.

Who is this for? This Fancy Buying 11.4V 24Wh replacement battery is aimed at ThinkPad owners who need a reliable OEM-style swap for aging or non-functional original batteries, technicians replacing packs in office machines, and travellers who prefer a lightweight spare for short-duration use. If you prioritize exact fit, installed safety features and a manufacturer-backed return/warranty policy, this battery offers a practical balance between safety and portability.
