Perfect fit for Dell n5040 and 60% charge out of box.

Perfect fit for my 10 year old Dell n5404. It had 60% charge out of the box. It took about 30-40 minutes to charge to 99% while in use.

Pros
  • Very happy so far. Exact fit and arrived charged to 83%. 100% charged now and I'm 100% satisfied.
Cons
  • The installation process may prove difficult for those with limited technical knowledge

Dell J1KND Replacement Battery

I have an old Inspiron N5110 and ordered a battery through NinjaBatt. It arrived 5 days earlier than expected which was a plus since my original Dell battery that came with the device was at 0% and not charging. The battery fit perfectly and it was at 60% charged upon installing and within an hour was at 100%. It's only been a few days now but so far so good. Thanks NinjaBatt.

Pros
  • Great purchase! My laptop is like brand new! Arrived in a timely manner and packed well. Thanks!
Cons
  • The battery may not be compatible with external power sources or charging ports

Great value. best in my review

Bought for a Dell N5030 running Linux Mint. I get about 2.5 hours of heavy use (Zoom calls, email and multiple tabs in Firefox). It will give about 4 hours of light use.

Pros
  • Computers & Accessories
Cons
  • The battery may not be covered under the laptop's existing guarantees or warranties

Great value! good for me

I am probably the least mechanical person I know.that being said, I have to say how EASY this battery is to install. Plus the value is great. My Dell Vostro is at least 10 years old.I thought I would have to purchase a new one, but, this battery did the trick. So far.so good!

Pros
  • It was what I expected
Cons
  • The battery may heat up the laptop more than the original battery

Ease of installation

I have an a Dell laptop that I've had for maybe ten years. I purchased before I retired and I am now 75 and stillusing it. The new battery made my laptop processing faster and the power/boot up process faster. Also it was extremely easy to install. All I did was move the necessary slides, take the old one out and put the new one in. It began booting up immediately. Thanks.

Won't hold charge for long.

I got the battery and it worked great for a few months, but then would not run my laptop for over an hour. Disappointing, to say the least, since it started out powering the laptop for three to four hours. Now I have to keep the laptop plugged in for fear it will die while I am using it.

Pros
  • Too soon to rate battery life.
Cons
  • The high-performance battery may not be worth the added cost for users on a budget

Inexpensive, easy installation, buy two :^)

It arrived quickly and with an 85% charge. Simple installation. Inexpensive. With my Dell Inspiration laptop it only provides 3 1/4 hour operating time when fully charged. Given this plus the price, it is reasonable to purchase the 2-pack of batteries so a fully charged backup battery can be carried along. I have not had it long enough to know how long this battery will last.

Pros
  • The battery was cheaper than previous replacements but the system accepted it right away. Simple.
Cons
  • The battery may malfunction and cause damage to the laptop's hardware

Skepticism alleviated

So I was pretty worried throughout this entire process of purchasing a replacement battery for my laptop (Dell Inspiron N7110) and I was going back and forth between many different products, indecisive. I eventually settled on the NinjaBatt but I was mighty skeptical about it because who isn't when purchasing electronics right?I received my NinjaBatt battery very quickly and the packing for it was perfect. No problems with it. When I put the battery into my laptop, it turned on fine and there…

Pros
  • The NinjaBatt battery charges quickly and efficiently, ensuring that your laptop is always ready when you need it.
Cons
  • The battery may not be compatible with specific charging devices or cords

Battery stays up for at least 80 minutes.

It keeps me from being tethered to the power source all the time.My laptop is used continually for work, shopping, ministry.

Pros
  • Snap in replacement
Cons
  • The battery may not be environmentally friendly due to its shorter lifespan

Battery Life is not what I expected.

When I re charge battery 100 percent it says I have 2 hours of life. But when I recheck it, with in 20 minutes, it then says that I have one hour of battery life. Am disappointed. The price I paid for it, I feel battery should have lasted longer. However I will admit it is very easy to install.

Pros
  • The NinjaBatt battery is easy to install with no special tools or skills required.
Cons
  • The battery may require additional care to avoid damage or degradation

Pros
  • It is compatible with a wide range of Dell laptop models, making it a versatile and practical solution for many users.

Good Quality Replacement Battery

I am very pleased with this battery. The last one I purchased for my Dell Inspiron N5050 from a different seller did not seem to fit perfectly, although it did work. This one is a perfect fit, and I'm glad I ordered from this company. Thanks for a quality and affordable product.

Pros
  • a quality product
Cons
  • Poca vida util

Works as advertised

Replaced a dead battery on a 10 year old Dell 3750 17" laptop. It works fine and has several hour battery life which is decent for this large old-technology laptop. Dell charges $120 to replace the 3750 battery, so the value is quite good, assuming the battery lifetime holds up.

Pros
  • Easy to install.
Cons
  • The battery may not hold a charge as well as advertised

Good price: my feedback

I’ve only had it for a couple of days, but it seems to be working well. I can now use my computer as a laptop. I went to Batteries & Bulbs and they said it would be over $100 for a replacement.

Pros
  • Very easy to install. Laptop came right up when I turned it on. High quality!!!
Cons
  • The battery may not hold a charge as well in cold temperatures
