I can’t tell you what it’s like long term. I’ve only had this battery for less than a month. Has been working well so far. Holds a charge so far but I haven’t really tried to deplete it. My E6420 can use this battery no problem. Unfortunately, I pretty much leave the laptop connected to AC power and the battery is just for backup purposes. I’ll have to update this 3 months from now, at least, to see any issues arises.

Ordered 3...they were of different wear levels, from 95% to 74% good. Guess that's to be expected from used batteries. All-in-all, good value.

The battery arrived very quickly. It is a perfect fit for my E6420 machine. I now have at least 4 hours of use. I make it through 3-4 hours of intense graphical engineering software classes and still have battery left for homework and emails and facebook after I get home.

Battery was perfect. It came half-charged and I was able to fully charge this battery and use it as described. The extra-capacity is great for the power hungry E6540 !! Very satisfied !!

Battery replaced an original Dell battery and also appears to be an OEM battery. Repurposed an old laptop and didn't want to put more money into it than it was worth. So far so good, only time will tell.
