Get longer battery life and improved laptop performance with a new Dell Studio 1558 battery from Laptop Battery Express. This battery is rated at 5200 mAh or 58 Whr. This is the highest rating available for a 6 cell battery pack. The higher the mAh rating, the longer your battery will run before it needs to be recharged again. There are no compatibility issues if your existing battery is rated at 4400 or 4800 mAh or a lower Whr. Simply put, more is better. And yes, this battery is probably better than your original!
Our batteries use the highest quality lithium-ion rechargeable battery cells that charge faster and last longer. Each battery is inspected, tested and backed by a 2 year warranty.
This battery will last up to 2.5 hours on a single charge. You can get even longer times when you lower your PC's power consumption, such as dimming the screen or closing unused programs.
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
3 to 6 months. Our inventory turns rapidly and you will always receive a freshly manufactured battery.
