Using my comperter for personal and business needs, at times, I end up using it without the plug in. This battery was not only at a great price, but the use of this battery has been great. The charge has well maintained, upon my setting the battery to discharge at a 15-20%, and then recharging it. The battery is maintaining itself, and providing the extended use. Freight and service was also great! One Happy Customer, Thanks!
The battery is what it states. Good purchase to replace my worn out battery.
