Replacement battery for Toshiba Satellite C50-B

This 4-cell lithium-ion unit is built as a direct replacement for a wide range of Toshiba Satellite models including the C50-B, C55-B, C70-C and L50-B families. It matches the original PA5184U-1BRS and PA5185U-1BRS part numbers so buyers can swap the old pack without adapter changes. The black casing fits the existing battery bay on supported laptops.

Thermal behaviour and power profile

The 14.8 V, 2200 mAh pack delivers 33 Wh of energy through an integrated smart control chip that manages charge current and discharge limits. Built-in protection circuits guard against short circuit, overheat and overload conditions during normal operation. No active cooling is required because the cell chemistry and management electronics are designed for passive heat dissipation inside the laptop chassis.

Build quality and daily handling

Dr. Battery has manufactured replacement packs since 2006 and subjects each unit to quality-control checks before shipment. The four internal cells are housed in a rigid housing that aligns with the original latch points on compatible Satellite and Satellite Pro models. A one-year warranty covers defects in materials and workmanship, giving owners a predictable service window for the replacement.

Questions about this item

How do I install this MPL16237P-11 battery in my Toshiba Satellite L50-B, and what step do people often miss?

Power off the laptop, unplug the AC adapter, slide the release latch, swap the pack, then press until the latch clicks; the step people miss is re-engaging the latch fully so the battery seats on the 14.8V contacts.

What maintenance or replacement will this 4-cell 2200mAh lithium-ion pack need later?

The 33Wh pack has no user-serviceable parts; when run-time no longer meets your needs, replace the entire battery with another 4-cell 14.8V unit matching the PA5184U-1BRS part number.

What limit appears first during sustained use of this 14.8V 2200mAh battery?

The 33Wh capacity is the first limit; under continuous load the pack will reach its rated capacity and require recharging before the thermal or protection circuits intervene.
