🔋 NinjaBatt Pro Battery for Asus A41-X550A A41-X550 R510C X550C X550L X550J R510L X550CA X552E X550V K550L F550V X550A P550C X550EA X550D R510 X550VX F550C - High-Performance [4 Cells/2600mAh/38Wh] Review

I bought this for my Asus Notebook X550C series that I've had since 2014 and obviously the battery died. So far so good, had it for about a month, holds the charge really well. Fit perfectly.

It works in my laptop as specified. How long remains to be seen. Looks like a quality battery! Well. update on my review. Battery is no longer holding a charge! Worked for maybe 9 mos.

I cannot yet attest to the longevity of the battery. It replaced one that had lasted 8 years. However, it was very, very easy to install and so far, it is doing the job.

Works perfectly. Apparently when the batteries die, there I some kind of sensor in the battery pack that prevents charging. This new Ninja battery fits perfectly and charges immediately. It was at about 70% charge when I first installed it. I used it for an hour after charging to 100% and it still has over 2 hours remaining.Thank Ninja too for their link to professional tips for Lithium batteries. It is important to know that you should never let them go below 20% charge! Thanks Ninja!Also…

The battery is dependable for at least a year. This is the second of these batteries I have ordered and used. I recommend not having your lap top plugged in all the time but allowing the battery to slowly run down during extended sleep modes.

I previously purchased a NijaBatt Pro for my old HP notebook. I was impressed with the increase in time the charge would last and how well it fit. When my son's ACER laptop's battery died, I decided to purchase one for his laptop. Again, it was a great fit, improved the longevity of use and charged fairly quickly.If I ever need another laptop battery, I'll be purchasing a NijaBatt Pro.

Great product, long duration, wonderful working, high capacity, proper charging, battery! Definitely a great purchase (so far, so good)!

I like this product because it has great vacuum package and fits on my laptop well.2 hour running capacity at casual mode, and It needs about 1.5-2 hour for fully chargeLet's see how it works in the feature

I have a K550 model. The original battery kept around 150 minutes but this battery only holds for 50 minutes if you are using your laptop for example for watching a movie or some regular tasks. It is a little pricier than the other generic ones and I expected it hold at least for 100 minutes.

Exact factory fit and lasts a couple hours or so on a full charge. This gives my laptop a 2nd life and I’ll probably be able to squeeze another two years of life out of it.Excellent value. Would definitely buy another battery from this company

I made a test before the review and the battery lasted 6 hours in save mode and 5 hours whitout save mode, worth the money Worked, an am happy!!

decent battery life, better than the old ninja battery that only lasted about a year before it refused to hold a charge any longer than an hour. this battery holds charge pretty good enough for it the last the majority of the day until needing to be plugged back in.even better it doesn't lose charge while idling

I couldn't find the right battery for my laptop at any of the local places without special ordering and a high price tag! Found this battery and it was PERFECT! Thank you!

Battery life is pathetic but an official Asus battery is $160. You get what you pay for. At least I can unplug my laptop without it immediately shutting down now. I get about an hour to and hour and a half out of it.

definitely easy to install. charge lasts decent amount, although I was working with a dead battery, so anything seems great right now. i've only bad the battery for a week, so I can't speak to its actual longevity, but overall i'm very pleased with the replacement and i'm happy my laptop is portable again.

Revain had the right battery that my laptop needed and it fit perfect and has a longer life span than the original. May not provide accurate battery life readings.

I loved the fact that as soon as I inserted the battery into my laptop it began working without an immediate charge. After charging and unplugging my laptop, the charge is still holding up nicely! Thank you!

Thanks to this my X550LB is being utilized efficiently again. No more fear of tripping on the power supply, no more power outages and accidentally switching off the power bar socket. I cannot comment yet on the battery life as I've just had it for 2 months and I do recall batteries deteriorating in output overtime. But at the moment the battery life is not at issue for me.

This battery is functional and the build quality is pretty good. Unfortunately, for light work loads and even idle the power time for my ASUS X550J sticks around 45-50 minutes. It works! It's just not very great capacity.
