It fits a wide range of Toshiba Satellite models including the A660, A665, C675, L640, L675, M645, P745 and P750 series. The unit is a brand-new GreenTech product supplied in black. It is not for users whose laptop requires a different voltage or physical connector.

Sustained output at 10.8 volts and 4400mAh capacity

The six-cell design delivers a nominal 10.8V with a 48Whr energy rating, tested for stable current and low self-discharge during extended use. Circuit protection guards against over-charge, over-discharge and short-circuit conditions. CE, FCC and RoHS certifications confirm the safety compliance. It is not for buyers who need a higher capacity pack for longer unplugged runtime.

Simple battery-bay swap with no tools required

The pack matches the original dimensions and latch mechanism, so installation consists of releasing the old battery and sliding this unit into the bay until it clicks. First charge should be allowed to complete fully before heavy use to calibrate the fuel gauge. It is not for technicians expecting a serviceable cell layout or external charge indicators.
