Replacement Battery for Satellite P55w Series

This 42Wh lithium-ion battery replaces the original power pack in Toshiba Satellite P55w-C5204 P55W-C5316 P55W-C5210 and P55W-C5210-4K models. It uses three premium A-grade cells and fits devices rated for either 10.8V or 11.1V operation. The unit is certified to CE and RoHS standards and carries a one-year warranty.

Three-Cell Pack and Protection Circuit

The three-cell construction keeps the pack slim while the built-in protection circuit guards against overcharge over-discharge and short circuits. No memory effect means the battery can be topped up at any time without capacity loss. Eco-friendly materials exclude lead and mercury from the manufacturing process.

Voltage Match and Initial Conditioning

The battery only works in laptops designed for 10.8V or 11.1V systems; other voltage ranges are not supported. Full capacity is reached after three complete charge and discharge cycles starting with an overnight charge. Buyers needing higher watt-hour ratings or additional cells for longer runtime will need a different solution.

Questions about this item

How many charge cycles will the 42 Wh lithium-ion battery last before it needs replacing?

The 42 Wh, 3-cell lithium-ion battery has no memory effect and uses A-grade cells; lithium-ion packs of this capacity typically retain useful capacity for several hundred full cycles.

What stops the 42 Wh pack from running longer on a single charge?

Capacity is fixed at 42 Wh; run-time ends when the stored energy is depleted, so heavier workloads drain it faster.

Does the battery get hot or draw extra power when the laptop runs all day?

The pack includes a protection circuit board and meets CE and RoHS safety standards; normal operation stays within the rated 10.8 V or 11.1 V range.
