### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great performance and excellent value for money.
  

*by M***  on Reviewed in the United Kingdom on 7 October 2024*

I recently installed the BRTONG B31N1429 battery in my ASUS laptop, and I’m pleased with the results. The installation process was straightforward—just remove the back cover, swap the old battery, and you’re good to go. It fit perfectly with no issues, and I was up and running in about 20 minutes.In terms of performance, this battery has been reliable. I’m getting a solid 6-8 hours of use, depending on what I’m doing, which is a massive improvement over my previous battery that barely lasted a couple of hours. Whether I’m working on documents or streaming content, the battery holds its charge well and doesn’t overheat, even during extended use.The overall build quality feels sturdy, and it’s clear that this is a well-made replacement. It slots in neatly, with no bulging or loose connections, which can be a concern with third-party replacements. The 48Wh capacity is enough to keep the laptop powered throughout the day without constantly searching for a plug socket, which has been a relief.If you’re looking to extend the life of an older laptop, this is a great, cost-effective solution. No frills, just solid performance and a good fit. I’d happily recommend it to anyone in need of a replacement battery.Rating: 5 out of 5 stars

    Good and reliable replacement battery for my laptop
  

*by K***Y on Reviewed in the United Kingdom on 3 September 2024*

My older battery was not holding the charge anymore so I decided to use this replacement and so far it did a good job.They actually installation process is quite easy as it perfectly fits in the previous battery slot and after installing it and charging for about two hours I was able to use my laptop without the charging cable for about four hours when working on the documents and about two hours and a half when I was watching some videos and I will also have noticed that it holds about two hours when I need to edit videos which is a very good performance considering that it also matches the performance of my battery one was new.Since I'm using it I did not encounter any issues, for example after using it for two hours of editing videos I did not notice any overheating which is a good sign and considering that I'm using it for over a week now and everything is fine I am quite satisfied with its performance.
