Ready replacement for Satellite laptops

This CPY battery matches the PA3817U-1BRS part number and fits a wide range of Toshiba Satellite models including the A660, C650, L745 and L755 series. It uses a six-cell lithium-ion pack rated at 48Wh and 10.8V to restore mobile power. The unit carries UL certification and is supplied new.

Drop-in fit for listed part numbers

The pack replaces original batteries such as PA3816U-1BRS, PA3817U-1BRS, PA3818U-1BRS and PA3819U-1BRS as well as the PABAS227 through PABAS230 series. No adapter or cabling changes are required; the battery slots directly into the existing compartment. This frees the user from hunting for discontinued OEM stock.

48Wh capacity for everyday workloads

At 48Wh the battery supports typical office tasks, web browsing and media playback on compatible Satellite chassis. Runtime will vary with screen brightness, processor load and battery age. Heavy workloads such as sustained gaming or video rendering will exhaust the charge more quickly.

Questions about this item

How long will the 48Wh capacity last under sustained load before the battery hits its limit?

The 48Wh rating gives a fixed energy store; run-time depends entirely on the laptop's power draw, so a heavier workload reaches the limit sooner.

Does the 6-cell Li-Ion pack run hot or make noise during all-day use?

Li-Ion cells have no moving parts and generate minimal heat under normal discharge; the pack is silent and stays close to chassis temperature.

Which Toshiba Satellite models must I already own for this PA3817U-1BRS battery to fit?

It fits the listed Satellite A, C, L, M, P, T and U series models such as L745, L750, L755, C650, A660 and P755.
