FOCUSTEC laptop battery 2600mAh 14.8V 4-cell for Toshiba Satellite C55 C55D C55T L55 L55D L55T

Replacement battery for Satellite C55 and L55

This new lithium-ion pack delivers 2600 mAh at 14.8 V and is compatible with 14.4 V systems. It replaces part numbers PA5184U-1BRS, PA5185U-1BRS, PA5186U-1BRS and PA5195U-1BRS across the listed Satellite C55, C55D, C55T, L55, L55D and L55T models. Grade A cells and built-in circuit protection support stable charging cycles. The unit carries FCC, CE and RoHS certification.

Check your current battery before ordering

Confirm that the original battery label matches one of the four part numbers above and that your laptop is a 15.6 inch Satellite model from the C55 or L55 families. The pack fits many sub-models such as C55-B5200, C55-B5300, C55-B5299, C55-B5202 and L55-C5346PL, but it is not universal across all Toshiba lines. Verify the voltage rating on the old cell reads 14.4 V or 14.8 V. Buyers who need a different form factor or a higher capacity cell should look elsewhere.

Build quality and daily use

The four-cell lithium-ion construction uses Grade A cells selected for fast charging and low self-discharge. Integrated protection circuits guard against over-charge, over-discharge and short-circuit events during everyday operation. No separate mounting hardware is required; the battery slides into the standard bay and locks with the laptop's existing latch mechanism. The 24 month manufacturer warranty and round-the-clock email support cover defects in materials and workmanship.
