HBFVG C41N2208 Laptop Battery Replacement for Asus RC71L PC71L NR2301L (2023) Gaming Handheld Series(15.48V 74Wh)

Excellent quality, easy installation you can follow on video, now I have game sessions of 2.5 hrs when playing in Balanced 18W and games in 900p. Big recommendation to place some aluminum protections or kapton tape between the RAM and the battery. I used it for a while without it but did it for extra safe measure. Vendor was quick and delivery was on time. Highly, highly recommended. Worth the extra price to have the protections here in Amazon.

HUGE IMPROVEMENT! I've had my ROG Ally Z1 Extreme since launch and my absolute biggest complaint about it has been the atrocious battery life. With the 74wh battery mod I've more than doubled my overall playtime with each charge.The install wasn't too bad, but I recommend watching a few tutorials on youtube to fully understand which plastic bits need to be trimmed from your back shell's interior. After I snipped the pieces needed, I lightly sanded them down to make sure no sharp points could come in contact with the battery once reassembled.After running a battery test and report through the control panel, I realized the max charge is actually 76wh 🙌If the battery life of the Ally is an annoyance for you, I highly recommend this mod!

Frankly, installation of this battery pack is a bit of a pain that takes careful effort to make sure it's done safely. Before buying, watch a YouTube video on how to install it, as it's a bit of an involved process. I'm a novice and was able to do it, as no steps are particularly "hard", but you do have to be very careful and meticulous with it to not damage the internal connectors or wiring. With that out of the way, this battery pack is INCREDIBLE. Anyone owning an ROG Ally knows that the biggest pain point is its battery life, and this battery pack almost completely fixes that issue. I've used it for about a week with the new one, and it nearly doubles the battery life. Here's an example.With the old battery, playing Rocket League on high settings at 15W and half-brightness would net me about 80 minutes of playtime. Not long enough for a daily train commute. With this new battery, I'm getting about 2.5 hours (150 mins) with the same settings which is more than enough time for me a day. Dropping down to lower settings and setting it to 10W, and the difference is even more drastic.There is a caveat to installing this battery, and that is that when the device is fully powered off, it can no longer charge at full speed 65W, only 45W max is supported. That means that if the device is completely shut down, charging times will be longer. This doesn't really impact me day to day as I usually keep mine in sleep mode when not in use.Overall, for about $60 this is an incredible value for the money.

Anyone looking for longer Ally battery life will be pleasantly surprised with this upgrade, though we'll have to see if any issues arise down the line. For my situation, I ended up wrapping my battery in aluminum tape to help with thermals based on review guides online.On the positive side, the capacity is as rated and I managed nearly 3 hours at 25 watts. Prep-work aside, the battery worked right away after closing up the system and plugging in the charger. I'm thrilled with the results.Update: 3-months in and I still think this is the best upgrade I could've picked up for the Ally.Doing the replacement is tedious and a bigger battery comes with increased charging time and doesn't charge at as high of a wattage as the stock battery. It's a small sacrifice to be able to get away from the wall. With the battery mod being so new, there are practically no long-term reviews to see if any major issues come up over time. I noticed my device get extremely warm on the back during my first charge, but haven't experienced anything like that since.It should be noted that this is a day two review.

So far so good. Pretty easy installation, battery capacity rating matches advertised capacity. Very much worth it, makes the original Ally playable!

I upgraded my ROG ALLY battery using this kit - it now runs for a much longer time! The slowest part was trimming the inside of the stock backplate flat so this oversized battery could fit.

Works well with all the tools needed.

Works great in the Rog Ally Z1E. Plenty of Youtube videos to show you how to install.
