Dr. Battery MPL16237P-01 4-cell 14.8V 2200mAh laptop battery

Replacement for Toshiba Satellite series

This 4-cell lithium-ion battery replaces original Toshiba packs for Satellite C50-B, C55-B, C55D-A, C55D-B, C55Dt-B, C55t-B, C70-C, C70D-C, E45, E45T, L50-B, L55-B and L55T-B models as well as Satellite Pro C50-B, C55-B and C55Dt-B units. It matches OEM part numbers PA5184U-1BRS, PA5185U, PA5185U-1BRS, PA5186U-1BRS and PA5195U-1BRS. Buyers who need a different voltage or a higher cell count should look elsewhere.

Installation and common issues

The pack fits the standard battery bay on the listed laptops and uses the original latch mechanism; no tools are required beyond a Phillips screwdriver for the bottom cover on some models. A built-in smart control chip manages charging and provides short-circuit, overheat and overload protection. The most frequent mistake is ordering without confirming the exact model suffix or original part number, which leads to a physical or electrical mismatch.

Capacity and runtime

Rated at 14.8V and 2200 mAh for 33 Wh, the battery supplies typical office workloads for several hours on a full charge. Heavy multi-tasking, maximum screen brightness or discrete graphics use will reduce that window noticeably. It is not intended for users who require all-day operation without access to mains power.
