Questions about this item

How long will the 4500mAh capacity last under continuous heavy use before needing a recharge?

The 4500mAh lithium cell delivers 16.36Wh at 3.85V. Actual runtime depends on the device's power draw; heavier loads deplete the charge faster.

Does the battery get hot or swell during all-day operation?

Built-in overcharge, over-discharge, over-voltage and short-circuit protection limits heat build-up. The 4.95mm slim profile fits the original bay without forcing the chassis.

Which specific device models and part numbers must I already own for this battery to fit?

Compatible devices: T790W, T790S, T790Z, T790Y, T790H. Matching part numbers: TLp043E1, TLP043E7. Verify yours before ordering.
