Charges up really quickly and maintains its battery for a fair amount of time. Fits my laptop, however can be a little bit loose, but that might be related to the age of my device Seems well put together and packaged well

I have always been scared of purchasing replacement batteries for laptops. The genuine originals always cost a bomb and a half, and all the cheap ones glibly advertised on eBay range in quality from dreadful to downright dangerous (as in burn your house down). Why did I choose the NinjaBatt brand? Id helped a friend replace the battery in his old MacBook Pro 17 inch - it was a NinjaBatt battery we'd purchased at the time. I was impressed with the build quality and performance. So, when my HP Pavilion Laptop needed a new battery, NinjaBatt was the logical choice. And yes, the battery is as good, perhaps even better than the original. And it won't burn my house down, or suddenly die prematurely. I'm one satisfied customer!

A battery for my HP 255 G5. The original was beginning to fade, I was concerned that it was a 3 cell battery and most replacements, including this one, are 4. Finding a detailed spec for the laptop revealed that it could accept either (the case is the same), HP classify them as HS03 or HS04. This new battery fit perfectly and the laptop was able to identify it and began charging. I was able to use the Windows monitor system to confirm the expected voltage and capacity etc. Note that the battery was supplied in a completely discharged state but after fully charging it indicated 37.5 Watt hours, considerably more than the old original. A test discharge proceeded smoothly, so far so good.

Great battery

Battery works perfectly fine

Originally when i got this battery i thought it was too good to be true as it was charging well and giving me more charge than i could ever imagine. I was over the moon. Then after about a month or so. for about 2 days i didn't charge my battery as i wasn't using my laptop during this period of time. Before i knew it i notice that once i accidentally disconnected my charger from the laptop (which was already connected for hours) it instantly turned off! After loads of checks by installing an up to date bios and uninstalling and re-installing the battery drivers in device manager I was still getting the HP error diagnostics shown in the attached picture. and zero % charge on the battery icon display even though charger is connected I then had to buy another type of HP battery which worked to prove the issue was with the NinjaBatt pro battery. Shocking is an understatement here. Amazon were able to refund me with no further questions, even though it was way after the allowed return date. To the point that Amazon maybe already aware of this type of issue who knows. was glad to get my money back. But also be aware that as it is a battery i had to use a courier service (refund included courier cost) and you have to do this quick as the time they need to receive the item is usually in only a few days once you receive the return labels. I really hope i just got a dodgy battery, but i have a bad feeling it wasn't, hence buyers beware after a few weeks/months.

This battery was perfect for my laptop and I'm very pleased with it. It was delivered on time and was excellent value for money. I spent time checking the pictures , codes and measurements of this battery to be sure it was the correct one for my laptop - time well spent.

Great product does the job and fits perfectly

Fait le job. S’adapte parfaitement.

Ya varios meses con la bateria, no defrauda. Mantiene la carga

I could not follow the stated procedure for first use of the battery, because the battery did not have enough charge, but it still works, so I am not complaining too much. Otherwise, I would have given 5 stars.

Had snel een vervangende accu nodig, deze werd overnight geleverd. Tijd zal leren hoe hij blijft werken. Maar heb er een goed gevoel over.

It fit perfectly and worked like it should. Now we will see if it lasts.
