The KingSener T470 L140BAT-2 is a 36WH 7.7V lithium-polymer battery built for the Thunderobot MixBook Air and compatible Clevo L140CU, L141CU, L140MU and L141MU chassis. It matches the original form factor for direct installation without modification. Buyers needing a different voltage or capacity should verify their original part number first.
Thermal Behaviour and Power Delivery
The pack uses Li-polymer cells rated at 36WH and 7.7V to deliver stable output during normal workloads. Internal protection circuitry guards against over-charge, over-discharge and short-circuit conditions. The supplier advises a full charge and discharge cycle two or three times on first use to calibrate the fuel gauge.

Questions about this item
How do I install the L140BAT-2 battery in my Thunderobot MixBook Air, and what step do people often miss?
Power off the laptop, remove the bottom case screws, disconnect the old battery connector before unscrewing it, then connect the new L140BAT-2 7.7V 36WH pack and secure it; the step most often missed is disconnecting the old battery cable first to avoid a short circuit.
What maintenance will the KingSener L140BAT-2 need later, and when should I replace it?
Perform a full charge and discharge cycle two or three times when new; if the laptop sits unused, charge above 80% at least once a month; replace the pack when runtime drops well below the original 36WH design capacity.
What is the first limit I will hit under sustained heavy load with this 36WH 7.7V battery?
The 36 watt-hour capacity is the limiting factor; under continuous high draw the pack will deplete faster than lower loads, so runtime ends when the stored 36WH is exhausted.
