This laptop battery replacement is typically superior to the original battery and is 100% compatible with your Sony Vaio notebook computer. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 1 year warranty.

You can expect about 2 hours to 2-1/2 hours of run time with this computer battery when new. Even longer run time can be acheived by minimizing your screen brightness and energy use.

This battery will be compatible with batteries rated at 4400 mAh & 4800 mAh capacities while providing up to 20% more run time.

Laptop Battery Express only deals with brand new premium computer batteries. We never carry recycled or used batteries. We only use the highest quality cells inside the battery pack so you will have a long service life (300-500 recharge cycles). We do not use cheaper battery cells which can wear out in a little as 6 months. Our inventory turns rapidly and you will always receive a freshly manufactured battery.

Like all Li-ion primary batteries, your run time will decline over time.
