Get longer battery life and improved laptop performance with a new replacement Sony Vaio PCG-71912L battery.

This Vaio PCG-71912L battery uses the highest quality components and lithium-ion cells. Higher quality cells mean a longer running, faster charging and lighter-weight battery.

Expected service life for this battery is 3 - 5 years. Cheaper batteries can wear out in as little as 6 months! (Just read the reviews on the cheap batteries on Amazon and eBay).

The higher mAh rating of 5200 is the specification that indicates the energy storage capacity of the battery. Our 5200 mAh capacity is much better than the 4400 mAh capacity of the low end batteries.

Li-ion batteries are not subject to the memory effect common with older battery technology. This means you can recharge your laptop any time without diminishing your battery capacity. Each PCG-71912L battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.

You can expect about 2 - 3 hours of run time with this Sony Vaio PCG-71912L battery when new, depending on your energy use.
