It is my husband (me. Our company had it shipped directly to her at college and we carefully explained to her how to condition the battery before use by following the instructions included in the shipment. I was impressed with how easy it was to install, how carefully it was packaged, and how easy it was to follow the instructions for how to treat it upon Since she has had it in place for a couple weeks now, she is reporting that her laptop now makes it through more than four hours of graphics-intensive classes without completely conking out.

I like the way it fits. This battery can last for about 3 hours, which is more than adequate for my usage patterns when I am not connected to the wall. My previous battery could last about 10 minutes at this point. I'll update if the longevity turns out to be poor, but so far it's going great! The following update has been posted on Almost 8 months in and the charge holds a lot less than it did when first bought. Now it only lasts about 2 hours 15 minutes. Even with the price tag, it still gets a four star from me, but I thought I'd be able to get over a year before experiencing such a loss in charge capacity.

In 2016, I bought a HP Pavilion gaming laptop, and it died recently. I was unable to find an original replacement battery on the internet. As opposed to the original battery, which was rated at 48 watt hours, this one's rated at 38 watt hours. I have not found a battery rated higher so far. As a replacement battery it does hold up pretty well compared to the original since it is made by a British or American company instead of a Chinese one. Additionally it should be taken into account that the original battery already had a smaller capacity because it was older and had been cycled plenty. Earlier yesterday, we had a whole day of power outages due to maintenance on the power lines, so I took full advantage of it to see if my laptop would last the rest of the day. With a fully charged cell phone, watching YouTube and editing Word documents while on power savings settings, I got 3 hours and 30 minutes out of it. Even though this is a gaming laptop, the overall performance is still good. Choosing this battery was important to me because this company is actually based in the US and UK and a $20 battery with cheap cells will not do. Although this laptop still rocks considering the cost, I saved at least some of the money I would have spent on a new laptop. Using some cameras, I took some photos comparing the new battery to the old one, as well as some stripped cells to see if they had a good quality. I can only see a small gap every time I insert the NinjaBatt, but everything else slides right in like the original.

I would give this product a 10/10 for both price and quality I have yet to use it for more than three days, but I will follow up in a month or so.

The battery I bought is to replace the one in my HP Pavillion laptop. It was fairly easy for me to install. After installing the laptop, I also noticed a slight gap, but it powered on no problem and had about 60 percent of its charge when I first got it. 100% was charged to my credit card I didn't spend much time on it. Although I used it today for work, I did not anticipate the battery life to be as good as it is. It has already dropped to 20% in two and a half hours. The device is fully charged after being plugged in. When 2 p. m. rolled around, I unplugged to participate in a Zoom meeting There are 50 minutes left in The following are the results by At 42% on 30th, it was down from 50%! Does my battery have a fault? It has been reported that other reviewers were able to use this battery for hours. This is something I will need to discuss with the company.

The NinjaBatt Pro battery was the first one I've used to replace a battery before my laptop died, so I was concerned to find a reliable one at a reasonable price. Once I finished doing the research for the battery, I found a reasonable solution. It took 1 day for me to receive the battery It should be a 1-day rather than a two-day Prime delivery on the day of purchase I found it very useful, so I am glad I did so. In order to ensure that the battery would arrive safely, the battery was packaged in an air cushion bag. Once the laptop was installed, I was able to use it immediately due to the battery being about 50% charged. There are also “tip” cards included in the battery box that will help you maximize its capacity. It was the product description on Amazon that gave me the ability to make the right choice. I took a picture of the old battery's part number and battery information to compare with the narrative My order was described in a way that eased any uncertainty I had. I liked the ease of installation of the battery It is easier to replace the old one than remove it. This battery cost a little more than others I found, but in my research, I feel that it is a quite acceptable price that is well worth it. My friends will recommend this brand to me when they are in need of.

The Ninja Battery Company replaced my NinjaBatt PRO. I initially had no problems with it and I could use my laptop for an average of 8 hours Just like the OEM factory original, it takes 9 hours to complete. The only problem is, after just 8 months of normal use, it no longer lasts 3 When I contacted Ninja Battery with regard to warranty coverage, they said "that's just the way it is". It's my fault.
Is that normal? I had a battery that lasted nearly three times as long as my original one.

The following review is still valid 9 months after it was completed in June 2020. There is still a lot of battery life left! Below is the review as it originally appeared The battery I received was easier to install on my HP laptop than the one I originally bought, and it began charging immediately. A total of 45 minutes were needed to get it to 100%. It started at 36% out of the box. It was such a relief to get my laptop up and running again after my original battery suddenly went to 0% and wouldn't Due to the recent arrival of the new laptop, I cannot really speak to the power or longevity of the battery, but I did pay a few dollars more for the premium battery in hopes it would last for a few years until I upgrade my Following an unplugged period of 25 minutes, the battery charge decreased from 100% to 95% and the remaining time for charging was stated as 2 hours, 53 minutes. This is good news for me.
