Questions about this item

How do I install the battery in my ThinkPad P40 Yoga, and what step do people miss?

Power off the laptop, remove the bottom case screws, disconnect the old battery cable, connect the new 11.4V pack, then reassemble; the step often missed is disconnecting the cable before lifting the old battery out.

What maintenance or replacement will this 3600 mAh Li-polymer pack need later?

No scheduled maintenance is required; replace the battery when run-time no longer meets your workload.

What limit appears first during sustained use of this 11.4V battery?

Integrated safety circuitry will cut power if the pack overheats, over-charges, over-discharges, or detects a short-circuit.
