Replacement battery for ThinkPad Yoga 12.5-inch

This KingSener 45N1706 lithium-ion battery replaces part numbers 45N1704, 45N1705 and 45N1707 in compatible Lenovo ThinkPad Yoga S1 and Yoga 12 models. It is built for owners who need a direct-fit replacement for a worn or failed original pack.

Thermals, noise and power draw

As a passive battery, it generates no fan noise and draws no power while installed; heat output is limited to normal cell resistance during charge and discharge cycles. The 14.8 V lithium-ion chemistry operates within standard laptop thermal envelopes without active cooling.

Capacity and voltage match

The pack delivers 3.18 Ah at 47 Wh with a nominal 14.8 V, matching the factory specification for the listed ThinkPad Yoga systems. Buyers whose machines require a different voltage or watt-hour rating should verify compatibility before purchase.

Questions about this item

How do I install the 45N1706 battery in my ThinkPad Yoga 12 without damaging the connector?

Power off the laptop and disconnect the AC adapter. Remove the bottom case screws, then lift the old pack. Align the 14.8V replacement's connector squarely with the motherboard header and press straight down until it clicks; forcing it at an angle bends the pins.

What replacement will this 3.18Ah lithium-ion pack need over its service life?

The internal cells degrade with each charge cycle. When run time falls well below the rated 47Wh, the entire 45N1706 unit must be swapped — no user-serviceable parts exist inside.

What limit appears first when the 45N1706 runs a sustained heavy load on a Yoga S1?

The 3018mAh cells hit their thermal ceiling before the 14.8V rail sags, causing the pack's protection circuit to throttle output current until temperatures drop.
