### ⭐⭐⭐⭐⭐ Excellent Batter for Older Laptop
*by T***Y on September 18, 2025*

Battery works fine in older Dell Inspiron 7010 laptop computer. The specifications come up as stated in the listing and the battery does not get overly hot. Good quality value.

### ⭐⭐⭐⭐⭐ good price and fast delivery!!
*by Z***O on September 19, 2025*

received 15 minutes ago and have it replaced, works great! thanks for the tools that comes with the battery....

### ⭐⭐⭐⭐⭐ If your laptop shuts down suddenly even though the battery is charged, this could be the problem
*by B***R on September 26, 2025*

So far so good on my Dell 7490 laptop. Battery was about 65% charged when received so I followed the instructions and charged it fully and am now trying to take it down to 5%, repeating that charge/deplete process several times. The battery (like all of them) does not come with the little power cable, which is easy to remove from the old and re attach to the new one, Just look at YouTube for instructions, and don't pitch your old battery until the new one is there so you can compare them side by side. The cable plug was slightly different on the new battery but not in any meaningful way.My original battery was working OK until all of a sudden the laptop would shut down even though the battery was charged above 90%. Then it would not restart unless I had it on the charger. When I removed the battery I could see the problem, that two of the four cells on the one side were enlarged, which you can see in the photo. So the battery didn't wear out, it just failed at a very rapid pace, over a matter of one week.
