Work great has replacement easy installation

I bought an ancient Dell E6520 Windows 7 laptop at a thrift store that turned out to be nothing but one big headache to get working but this battery turned out to be the one brightside in that journey. The E6520 that I bought this for had an original 9 cell extended battery which was dead so I was forced to replace it. There are 3 battery choices for the E6520, a 4 cell, 6 cell, and a 9 cell. The 9 cell is the extended battery that provides the longest battery life but it also extends from the laptop body like the Hunchback of Notre-Dame and since I didn't plan on using the laptop that often unplugged I went with this 6 cell battery that advertised decent watt hours and fit the outline of the laptop. The 4 and 6 cell batteries have the same dimensions but the 4 cell battery would have been useless in my opinion. The reason I went with this brand is that the seller wasn't picturing the original Dell battery nor advertising their battery as genuine since new Dell batteries don't exist for any of their old laptops so the seller got my respect for being honest and not being shady. Secondly, unlike most of the white label brands on Amazon this brand appears to be made by an actual manufacturer of batteries among other things so I gave additional points for that. My final opinion was formed when I received the battery. It was physically well manufactured and fit nicely into the laptop which I can't say has always been my experience with other brands of batteries for other brands of laptops. My real pleasure and shock came from how long this battery's charge lasts. Under heavy use of downloading programs and installing them and updating Windows it lasts a little over 2 hours. Now when using the laptop for light use such as streaming videos I can't tell you how long it lasts because when I was doing that I got nowhere close to draining it to 20% in over 3 hours so I gave up and went to sleep and have care about testing it further. My only complaint about this brand is that they don't have a big product line and only sell a very limited number of battery models. After my experience with this battery I would have loved to replaced other laptop batteries with this brand but they don't make them.

This battery is the perfect fit and works perfectly in my HP laptop. It was at about 80% when we started and charged right up. Did a couple discharge Cycles as the instructions said. It has been holding the charge 100% and has good battery life as it runs the laptop for hours. The quality is excellent.

So not gonna lie when I was getting a better battery I kind of expected like at least half a days worth of lifetime, but imma be real for a moment my previous battery would hold a charge for 1-5min before shutting my laptop down when it wasn't plugged in. This one has a charge of about 2 hours and about 15min which is 2hours and 10min more than what I had so that's a big increase. That and it not only works but is very easy to install and actually has a rather favorable price for what it can do at least I think so. It works with my Hp pavilion g7 laptop so compatibility wasn't an issue either. All that said I'm not gonna complain cause it gives me much more time alive when say power goes out and a better battery doesn't pull as much power to stay running. If I'm being honest only reason I'm not giving 5 stars is was expecting more charge but as I said before I'm not complaining its better than what I had before and that's all that matters. Plus logically speaking the Hp pavilion g7 series is starting to get old and outdated so kind of expected if ya think about it. Still if ya need a new battery this is definitely worth it.

Still working after a couple of years. I tend to wait a while before reviewing to see if the product really works as advertized. This battery has proven to be affordable and reliable over years of use.

I simply needs a new battery for this laptop I'm on. Works very well. Thank you.

I was going to pitch my old HP laptop because it would not hold a charge, and I figured a new battery would be too expensive. Wrong, these are cheap and work like the factory one the laptop came with.

only had for 2 weeks. working in HP 2000.

This battery is a durable unit and has slightly more MAH than the original. Depending on the use I can get up to 5 hours or more between charges .It is easy to install and use.This is the second 1 as I have had this laptop for almost 15 years now. Great battery at a reasonable price.

Takes too long to charge

could not evaluate the connector were an inch too far. The size was perfect but it would not fit.

The price was so low compared to what I was quoted at two computer stores. Works well.

Battery worked as advertised. Reinvigorated old computer.
