What this battery replaces
This new GreenTech battery replaces a long list of Lenovo part numbers including L21C3PF0, L21L3PF0, L21M3PF0, L21M3PF1 and multiple 5B11 and SB11 codes. It fits IdeaPad 1 models with 14 and 15 inch designations across several platform variants. Buyers who need a different voltage or cell count cannot use this unit.
Practical limits of the 3-cell design
The pack uses three lithium-ion cells wired for 11.25 volts and 3735 milliampere-hours, delivering 42 watt-hours total. That capacity is fixed by the cell count and chemistry; it cannot be expanded without changing the physical pack. Systems that demand a higher watt-hour rating will not gain runtime from this replacement.
The spec that decides fit
Match your original part number against the supported list — L21L3PF0, 5B11D70891, SB11D70892 and the other codes shown — before ordering. Only an exact part-number match guarantees the connector, shape and firmware handshake will work with your specific IdeaPad 1 model.

Questions about this item

What does the 42Wh rating mean for daily use on my IdeaPad 1-14 or 1-15?
At 11.25V and 3735mAh the pack stores 42Wh, giving a typical full charge for the 14-inch and 15-inch IdeaPad 1 models listed.
Does the three-cell lithium-ion design use a standard connector that fits the IdeaPad 1-14ALC7 motherboard?
