This is a brand new high capacity IBM Lenovo ThinkPad X60 and X61 series battery. This battery replaces the IBM Lenovo ThinkPad X60, X60s, X61, X61s series laptop batteries and additional machines which are listed at the extreme bottom of this web page.

This long run battery will run at least 50% longer than the standard capacity battery that ships standard with your laptop. This battery is going to be larger than the original battery and will protrude to the rear of the laptop but will not be noticed when the screen is open. It will still snap into your computer and power it up

The added run time is achieved with an additional 3 cells inside the cartridge. Users of this battery pack experience an additional 1-2 hours of run time over the standard battery. Estimated run time with this battery is 3-5 hours. Longer run times can be achieved by minimizing the power use, especially the screen brightness. If you are using the docking station, the added battery size will interfere with your docking connection. The smaller 4 cell battery will better serve you.

This means you can recharge your laptop any time without diminishing your battery capacity. This Lenovo ThinkPad X60 battery is 100% compatible with your Lenovo ThinkPad. Each battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.

These are the highest quality Li-ion batteries on the market today and superior to batteries rated at 4400 & 4800 mAh. This battery will deliver more run time than cheaper 4 cell versions.
