This is working for my Dell laptop so far. I had to replace the battery after almost 2 years of use (which is the typical lifespan of a laptop battery) and this one has let me keep using my laptop. I've only had it for a couple of days though, will update review if there is any issue.

My old battery dead and I was just wondering where I can buy some. I'm very glad that they were selling some Laptop battery just when I needed one for my DELL inspiron 17 5000 series computer. For this, as I give to all the others, i give it a five star rate.

My laptops wasnt eorking because my batter was shot, got this one and it had already had a 46% charge in it, but my plug in wasnt working so it held a charge but didnt recharge, although i think this is the laptop/chargee cables problem

I am very disgusted with your company, this battery do not fit DELL INSPIRON 15 3000 series as you advertise.You have practically take out my money from my pocket thanks to your mistake. I could not make a return becauseit will cost to me 3 times the price i paid for the battery, i live in dominican republic.VERY VERY THANKS I HOPE MY MONEY MAKE YOU MORE RICH AND GOD FORGIVE YOU.

Got just under 3 months of use from this replacement battery. Expected it to work for much longer! Unfortunately my computer only powers on for a few minutes now before shutting itself off, even with the adapter plugged in.

While the Battery did work I would have expected it to work longer than 5 months which was all it lasted I guess you get what you pay for if it is something cheap and not long lasting you are looking for than this is ok but I was expecting at least a year from the battery.

No issues so far after 2 months of use. Holds a charge well. Works as advertised.

6 months after I purchased this battery, I tried using it, and it did not hold any charge. I contacted the seller, however, and they kindly sent a replacement battery. It's only been a couple days, but the replacement battery is working well.
