Use it to find the battery in the yellow search facility.

Voltage and capacity :
Capacity (mAH) indicates how long the battery will last between charges. Voltage must match the operating voltage of your laptop.

Battery components:

Battery Lifetime
After 2 years' use a battery will have retained only 25% of its original capacity.

Voltage & mAH
The battery voltage must match the operating voltage of your laptop. This will always be the case if you have selected the correct battery using one of the above methods.

Capacity in mAH (milli-amp hours) indicates how long the battery will power your laptop between charges. If your laptop consumes 1000 mA, a 4400 mAH battery will power it for approximately 4.4 hours, whereas a 6600 mAH battery will power it for about 6.6 hours.

Lithium-ion
All our batteries use the latest lithium-ion technology, which means they will not suffer from “memory effect”

They will fit your laptop just like the original.

They will give the same or higher capacity (= time between charges) as the original.

They are safety checked (over-temperature, short-circuit...)

They conform to CE and ROHS standards.

They are built using lithium-ion technology
