NinjaBatt Pro Battery for HP 746641-001 740715-001 OA04 OA03 15-R029WM 15-R052NR 15-R015DX 15-G020DX 15-R137WM 15-D035DX 250 G3 15-D020DX HSTNN-LB5Y 0AO3 - Premium Cells [4 Cells/2600mAh/41wh]

I recently bought a 4 year old HP laptop for $20 because the previous owner (1) bought a new one, and (2) kept throwing a start up error.. with that in mind, I bought it and reset everything, and the code it was giving was for a bad battery. After posting a question to some forums about aftermarket replacement batteries for my model (because HP didn't sell them anymore), I was referred to this brand. I am thoroughly happy with the fit, and the packaging as well! It even came with a 50% charge. I've only had it in the laptop for a few minutes, but upon start up, the error code was gone, so I think this fixed that problem as well. For any who are wondering.. my laptop is an HP 15-d035dx. This battery (the model I ordered anyway) is an exact fit. Thank you!

Battery arrived quickly and was easy to install. It is amazing having a battery again that I can charge and then use my laptop without the need of having it plugged in all the time like was nessary with my old battery when it died. I found their tips on prolonging my battery life to be very helpful so that this battery will last as long as possible. I choose the pro because I wanted to make sure I had a battery that lasted a lot longer than the original and I think it was worth the extra money to have that reassurance.

The Ninja battery that I bought for my HP computer was made well. All the data matched the battery to my computer but the connection from the battery to the computer was off by about a 1/2 of a millimeter so it did not mate up smoothly. I gave it an overall rating of 4 out of 5 stars because the return was non hassle and the product was well made (except the preciseness of the fit).

This is absolutely perfect and it fits the laptop perfectly & comfortably for our 10 year old daughter. The material is very, very, durable and it has a much longer battery life than the original battery that came with the HP 15-g100 Notebook PC. This is a much older HP laptop but since installing the new battery, it runs like new!!!

This battery is exactly what I was looking for! My older HP laptop and it's OEM battery was not wanting to hold a decent charge, where as it would charge to 100% and then I could only get like 10-15 mins before it was completely dead! Now, with this Ninjabatt Pro battery, I now get DAYS use on a full charge! Definitely would recommend following the included tips to better serve your use and to better the longevity of this battery! Will for now on only buy this battery when needed for my laptop...until I upgrade!

My HP laptops battery had gone completely dead where it wouldn’t turn on unless it was plugged in. The battery wouldn’t even charge and the battery wasn’t even old. I replaced it with this product and have had no problems as of yet, works great!

I spent the extra money on the pro battery because it has "samsung" cells and is supposed to be a better battery then the non pro. Installed very easily. I charge as soon as I got it to make sure it got a full charge. But the battery seems to deplete rather quickly. Kinda disappointed.

Great product for the price! The battery was easy to install and charge. It does come with caveats in terms of battery life. You are instructed never to let it get completely depleted of power because it will harm its charging properties. So you get nervous about watching the power bar on your screen and as such end up plugging it back in to charge when the power bars get to one which is about 1 and half hours. But otherwise does the job!
