Compatible replacement battery

This new lithium-ion battery replaces part numbers PA5212U-1BRS and PABAS283 for Toshiba Satellite Pro R50, R50-B, R50-C, Tecra A40-C, A50-C, C50-B, Z50 and Z50-C series laptops. It supplies 14.8V and a rated capacity of 45Wh or 2800mAh in a black housing. The unit is sold as a direct replacement for the original pack.

Who this suits and who should look elsewhere

Owners of the listed Toshiba models who need a fresh 14.8V pack will find the correct fit and voltage here. Buyers whose laptop requires a different voltage, a different connector layout or a higher capacity than 45Wh should look elsewhere. The battery is not suitable for models outside the Satellite Pro R50, Tecra A40-C, A50-C, C50-B, Z50 or Z50-C families.

Deciding specification: 14.8V 45Wh capacity

The single figure that decides compatibility is the 14.8V 45Wh rating. If the original battery shows 14.8V and approximately 45Wh or 2800mAh this replacement will match the electrical requirements. A different voltage or a substantially different watt-hour value means the part is not correct for that machine.

Questions about this item

How do I install the PA5212U-1BRS battery in my Satellite Pro R50, and which step do people often miss?

Power off the laptop, unplug the AC adapter, slide the release latch to unlock the old pack, lift it out, align the new battery contacts with the bay, press firmly until the latch clicks, then charge fully before first use.

What maintenance or replacement will the PABAS283 lithium-ion pack need later?

The 14.8V 45Wh cell loses capacity over time; after several hundred charge cycles the real 2600mAh runtime shortens, so replace the pack when it no longer holds enough charge for your work.

What limit appears first during sustained use of this 2800mAh battery?

The 45Wh energy rating caps total runtime per charge; under continuous load the pack depletes before any thermal or voltage limit is reached.
