Replacement battery for Toshiba Satellite

This 6-cell lithium-ion unit replaces the original PA3817U-1BRS pack in Satellite C655, C675, L645, L655, L675, L745, L755, P745, P755, P775, M645, A660 and A655 series notebooks. It delivers 11.1 volts nominal with 10.8-volt compatibility and a rated capacity of 5200mAh. The pack suits owners who need a direct-fit replacement for an ageing or failed factory battery.

Thermals, noise and power draw

As a passive component the battery generates no audible noise and adds no active cooling load to the system. It accepts charge from the laptop’s existing power circuitry at the standard voltage range and supplies current on demand during mobile use. Internal protection circuits guard against over-charge, over-discharge and short-circuit conditions.

Certified safety and compatibility

The pack carries CE, RoHS and FCC certifications and includes built-in circuit protection for stable operation. It cross-references Toshiba part numbers PA3816U-1BRS, PA3817U-1BRS, PA3818U-1BRS, PA3819U-1BRS and PABAS227 through PABAS230. Buyers whose laptops use a different form factor or voltage specification will need a different replacement.

Questions about this item

How do I install the PISKEKAT 6 Cell battery in my Toshiba Satellite C655, and what step is often missed?

Power off the laptop, unplug the AC adapter, slide the release latch to unlock the old pack, remove it, insert the new battery until the latch clicks, then charge fully before first use.

What maintenance will the 11.1V 5200mAh Li-ion pack need over its life?

No scheduled maintenance is required; keep contacts clean, avoid deep discharges, store around 50 % charge if unused for weeks, and replace the pack when runtime no longer meets your needs.

What limit appears first during sustained heavy use of this 6 Cell battery?

The pack’s 5200mAh capacity determines runtime; under continuous high load the voltage will sag to the cutoff threshold and the laptop will shut down to protect the cells.
