Compatible Satellite models

This 6-cell lithium-ion battery replaces the original pack in Toshiba Satellite A665, A665D, L635, L735 and L755 series laptops. It delivers 5200 mAh at 11.1 V and fits devices rated for 10.8 V or 11.1 V. The pack uses A-grade cells and a built-in protection circuit board. It is certified to CE and RoHS standards and carries a one-year warranty.

Thermals, noise and power draw

Lithium-ion chemistry produces no audible noise and generates minimal heat during normal discharge. The integrated protection circuit manages voltage, current and temperature to keep the pack within safe limits. Power draw follows the laptop's own demand; the battery itself adds no extra consumption. Eco-friendly construction avoids lead and mercury.

Sustained load behaviour

The 5200 mAh capacity supports extended runtime under continuous workloads such as video playback or document editing. Full capacity is reached after three complete charge and discharge cycles. The protection circuit prevents over-discharge and thermal stress during long sessions. The pack is tested before shipment and backed by a one-year warranty.

Questions about this item

How do I install this 11.1V 5200mAh 6-cell battery in my Satellite A665-S6094, and what step do people often miss?

Power off the laptop, unplug the AC adapter, slide the old pack out, insert the new one until the latch clicks, then charge it overnight before first use to reach full capacity.

What maintenance will this Lithium-Ion 6-cell pack need later to keep its 5200mAh capacity?

Perform a full charge and discharge cycle every few weeks; the pack has no memory effect, but regular cycling keeps the cells balanced and the protection circuit accurate.

What limit appears first when I run this 11.1V battery continuously under heavy load?

The 5200mAh capacity determines runtime; sustained high draw will deplete the 6 cells faster and trigger the built-in protection circuit to shut down the pack.
