Replacement Battery for Lenovo ThinkPad X1 Yoga

This 4-cell lithium-ion battery delivers 54 Wh at 17.6 V and is built to match the original Lenovo part for the ThinkPad X1 Yoga third generation. It replaces OEM numbers 01AV475, 01AV499 and 02DL003. The unit is supplied new and carries a one-year limited warranty from Total Micro Technologies.

Thermals, Noise and Power Draw in Normal Use

The battery operates silently with no moving parts and generates only modest warmth during typical charge and discharge cycles. Its 54 Wh capacity supports standard mobile workloads without excessive heat buildup. Power delivery remains stable across the 17.6 V nominal voltage range.

Upgrade Context and When the Jump Is Worth It

This pack restores original runtime for a ThinkPad X1 Yoga 3rd Gen whose factory battery no longer holds a useful charge. It is not suited for users who need extended-capacity options beyond 54 Wh or for other laptop models. The swap makes sense when the existing cell shows reduced capacity or swelling.

Questions about this item

How do I install the Total Micro L17M4P71TM battery in my ThinkPad X1 Yoga 3rd Gen and what step is often missed?

Power off the laptop, remove the bottom case screws, disconnect the old battery connector, fit the new 4-cell pack, reconnect the cable securely, then reassemble; the step often missed is reconnecting the battery cable before closing the case.

What maintenance or replacement will the L17M4P71TM need over time?

The 54WHR lithium-ion pack loses capacity with each charge cycle; plan to replace it when run-time no longer meets your needs.

What limit appears first during sustained use of this 17.6V battery?

The 54WHR capacity determines how long the ThinkPad X1 Yoga 3rd Gen can run before the battery must be recharged.
