I wish there was a 4.5 stars because it is so close but not a 5 out of 5. The replacement battery is probably less than 1mm too wide. This has created a problem of seating to replacement battery, were it is “Stubborn” to lock into place, yes this laptopOn 10 years old and I willing to deal with a littleAdjustment to get the battery to lock into place.Even with this nag I would be hesitant to buy an OEM battery at 3x the cost. The decision is ultimately up to you but I am happy with the performance and cost toRevive a 10-year-old laptop, grandma is rocking again!

I was having such a hard time getting the correct battery for my Dell inspiron 15 3000. Thus was finally the correct battery for my laptop and I will definitely be ordering a second battery for my work laptop which come to find out is the same one. But I would buy 2 since they're a great price

Battery fits great, has detailed instructions on how to calibrate the battery and monitor. Lasts longer than the previous battery which is a big plus. Will make it much easier to use my laptop when not able to plug in.

The shape of the battery is slightly thicker in this non-OEM part, but that is used to a good effect, as it angles the keyboard, ever so slightly up, at the back, probably no more than 5mm(ish!) and so I wasn't too fussed about that.I had read reviews about other batteries not fitting well and discarded those from my purchase plan, settling for this battery that had positive reviews that I found to be accurate and beneficial.The battery came partially charged (to about 80%) and it didn't take long to get that to 100% before I started using it. From there I used my laptop for about 60-70 minutes and when I checked it before shutting down, it was at 94% with a suggested 8 more hours of use.I appreciate that new battery cells hold their charge for longer than the OEM one I'd had for about 6-7 years (Dell's battery, REALLY lasted well, in my opinion) and time will tell if this remains to be a solid purchase.Worthy of your consideration and a strong 5 stars at the start.

When my battery went out a year ago, I purchased an off market battery from a Battery Outlet store. It advertised as a replacement for my old Dell Laptop. Had many problems. At first, I thought it was due to the age of my laptop. Kept getting messages about the need to set up utilities. It was this replacement battery. Eventually, it went out.This NinjaBat battery has performed and functioned beyond my expectations. The NinjaBat battery company also gave me directions on how to properly use the battery. Finally, an after market Dell battery that works for specific Dell laptop model.I am well pleased. I highly recommend the NinjaBat Battery for your laptop battery replacement needs.

This is the longest lasting battery I have ever used. My computer is an old Dell laptop purchased because it was the only Windows 7 available at the time. I have replaced the battery previously with a Dell battery. This battery lasts three times longer than the original and the Dell replacement. I always run my computer on high performance, and this battery gives me over three hours of battery life consistently. This is my third 14" or larger, and I've had two 13" or less. This is the longest lasting battery I have ever had.

Product is good and easy to install but not fit perfectly, a little part is outside from the battery cell. Otherwise battery life is good.
