Ninja Batteries are always my go-to when replacing laptop batteries. I’ve used them multiple times for customer repairs and personal devices, and I’ve never had a single dud. These batteries are solidly built, reliable, and hold a charge exactly as advertised. My customers are always satisfied, and I never have to worry about safety or premature failure. Installation is simple and straightforward—even if you’re not a tech pro, swapping it in is a breeze with the proper tools. Fitment is perfect, just like OEM, with no forcing or awkward alignment. Once installed, the battery charged up quickly without overheating, and it holds a solid, long-lasting charge that rivals or even outperforms some stock batteries. 🔋⚡ Compared to the cheap knock-offs out there that are a fire hazard waiting to happen 🔥, Ninja gives me peace of mind. The packaging is professional, and the battery comes well protected. Even after several charge cycles, the performance is consistent and dependable. If you're looking for a safe, high-performance replacement battery that won’t fry your motherboard or burn your house down, this is it. Highly recommend for techs, students, and DIYers alike! 🛠️✅

I got one of these a couple years ago for my 7110 and I always thought it was defective or incompatible with my Dell 7110 because it wouldn't charge. What would happen is that the battery light would alternately flash orange and white and the laptop wouldn't charge. So I figured I'd try another one so I ordered a new one and plopped it in and same behavior - no charge and wildly flashing battery light. I thought great my old 7110 is done and I need a new laptop. But before committing to a new laptop, I did some searching on this flashing light issue. Some folks said it was the power adapter but the bios recognized it as a 90w adapter. Others said it was the power jack - gets broken somehow. Others said it was Windows software, etc, etc... Somehow I stumbled across a Dell troubleshooting site and a person had posted a fix that corrected this issue on their 7110 - so I thought what have I got to lose (this only applies to the 7110 afaik so don't try this on other Dells and if you do, it's all on you!!!): Boot up Windows normally with AC adapter plugged in. While Windows is booted - remove the battery pack - yes - remove the battery pack while windows is running. Just take it out...do it! Windows continues to run but it will indicate that the battery is missing. Open Device Manager and click on the Batteries entry: Delete the AC adapter and the compliant batter y entries. Uninstall them completely. Reboot with the battery pack still out of the laptop and get to the Windows desktop. At this point the battery light should be out completely and there will be an X in the battery icon on the task bar. Now reinsert the battery pack - yes - put the battery back in the while Windows is running. Some things will happen. Reboot. When my 7110 came back up, the battery started charging and the light was a solid white while the battery charged. No orange/amber light was seen and it fully charged the new pack from 80% (out of the box) to 100% in about 30 minutes. So with all that said and done, I have two battery packs and a working laptop. These lithium packs are nice and pretty solid so I give them a 5. They fit without drama and seem to charge fast and hold a charge longer than the OEM pack did. Thanks

I made the mistake of leaving my laptop plugged in but unused for many months. When I finally turned it in again, I was getting a critical battery message. I ordered the replacement, which I felt was a reasonable price. It came in the usual Prime time, nicely packaged in a box with padding and informative instructions. I now know what to do if I neglect my laptop again! This battery fit perfectly and so far is working great. Longevity is unproven as I just replaced the old one, but I still recommend it.

easy install. battery lasts at least a couple hours now (my last one was less than an hour....), so I'm happy given the price.

Work perfect

Battery was a little swollen when it arrived. I thought maybe I was imagining it. I installed it and it has swollen to the point the bottom cover is split open. I am also getting a Windows battery error message. I'm frustrated that I got a bad one and have to go through the hassle of exchanging and installing again. I have not been able to get a response from the company. "Jane" reached out when i emailed support asking for photos. I sent them twice and gotten no response. My laptop has been without a functioning battery for over a week now with no resolution in sight.

Easy to install. Good price. Helps performance all around.

This was a good purchase. The replacement battery works just as well as the original one. Just make sure to follow the instructions that come with it so that you can prolong its life.

The battery appears to be of good quality and fits well like the original oem battery. I have used for 2 weeks on and off. Everything is working well so far. Fully charges and hold a good charge. Tip: to calibrate battery, I initially fully charged this battery and left the charger connected for an additional hour. I then used my laptop on battery power (ac power off) until the low battery warning. Then fully charge the battery and use normally. Keep in mind there are other factors that affect battery life, such as a fan on high all the time, due to overheating (clean cpu fan and reapply thermal paste) or screen at maximum brightness. Really happy with purchase.

Quality seems good. Works well.

buena calidad,fácil de cambiar el equipo va perfecto.

بائع غير أمين لا انصح الشراء منه. أرسل بطارية عادية وليست النوع المعروض. كنت ناوي استرجعها لكن احتياجي لبطارية لم استرجعها. رجاء الحذر

La batería funciona para el modelo que la compré DELL N 4050, se ve de mucha calidad se nota desde la caja en la que viene, muy bien protegida anti golpes y con manuales y todo. Dura lo esperado 3 horas para el alto consumo que tiene la laptop
