So, you think it's just a battery and nothing to get excited about? Not so, it's up to 5.8 hours more freedom. Freedom from your desk, freedom from being tethered to a wall outlet and freedom to go where you want to. Now, isn't that worth carrying around an extra 0.73 pounds? I thought so.

It works with Lenovo notebook computers including the ThinkPad R60e, R60, T60p, R61, R61e, T60, T61 and Z60m series.

  • newegg 5.8-hour Battery Life The ThinkPad 40Y6799 6-cell battery provides your ThinkPad notebook computer with up to 5.8 hours battery time for extended use without accessing to a power outlet.
  • newegg ThinkPad T60/R60 Series Compatible The ThinkPad 40Y6799 battery supports ThinkPad notebook computers including the ThinkPad R60e, R60, T60p, R61, R61e, T60, T61 and Z60m Series. As a second battery, the ThinkPad 40Y6799 can be swapped easily for extended computing.

1 out of 5 eggsDid fine for exactly a year

Pros: The battery worked well for almost exactly a year. Would give up to 2 hours of use time.

Cons: Is dying now and gives barely 50 minutes of use, and looks like it'll get worse rapidly.

Other Thoughts: What am I doing wrong here? If I need to buy a new battery every year, this is going to make the computer really expensive over the long term!

5 out of 5 eggsThe real deal.

Pros: Genuine OEM battery.

Cons: Expensive.

Other Thoughts: Beware, there are counterfeit batteries out there made to look like the real factory part. These batteries don't hold nearly the charge and die after a few months. Be sure to buy batteries from a reputable seller like Newegg that stands behind the products they sell.

4 out of 5 eggsIt's a battery

Pros: It's a real ThinkPad battery, not a knockoff, a refurb, or a refilled one prone to charging issues and other stuff. Good capacity, relatively new.

Cons: Expensive.

Other Thoughts: Check Lenovo's support website, then go on the product recall page. They've recalled quite a few batteries, including these batteries. If you do have an affected battery, you get a brand new one for free. If that fails, you can always buy one or go without. Newegg and UPS got it to me overnight, so I'm satisfied with my purchase.

5 out of 5 eggs

Pros: Much more compact than the 9 cell battery, yet good run time.

Cons: No charge level indicators like some other laptop manufacturers put in their batteries.

Other Thoughts: A spare battery is always nice to have. Fits well in your hand if holding the laptop by the back.
