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

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.

Followed a couple YouTube videos to protect the battery from heat and I’ve had 0 issues with longevity. It’s been almost a year now and I’m still very happy with the upgrade.

Update: After just over 5 months the battery has only been charging to 58% and will not go any higher. I validated the battery capacity by opening CMD and running a battery health report, it showed 74kwh. I shutdown the Ally, unplugged it, opened the back, disconnected the battery, held the power button down for 30 seconds (discharges the capacitors), plugged the battery back in, attached the backplate, plugged in the power adapter, and turned the Ally on and the battery percentage was accurately reflecting 100%. Original Review: This battery has given me significantly longer run times for my Ally and I have only been charging to 80%. I can play at 17w for 60 mins and will have only dropped to around 53%. I did not add an aluminum plate to the bottom of the battery as it is unnecessary and perpetuated by YouTube Videos and people taking it as gospel. There has been no proof it is required by anyone that is qualified to make such opinions. Make sure you move the pad from the RAM and drop it down to the section lower and it will prop the battery up as well as those foam inserts you cut out. I also used the rubber pads from the original battery to keep it secure. No issues playing the game at the highest wattage either.

Battery arrived visibly damaged. The outer wrap/casing appears melted, bubbled, and wrinkled, especially along the edge. Since this is a Li-ion battery, I do not feel safe charging or using it due to possible fire or failure risk. I would be careful

Not sure why but battery started tidying st perceived 20% left now it's increased to 30% when it turns off I'll try another just to see if it was just mines but not sure why. The kit does come with everything needed to install. It also shows Asustek battery on Windows 11 battery Info. However, still had the above issues.

Holding up very well so far. It's a hige upgrade to battery capacity!

Battery install was not too bad. Most of the tools needed, two screwdrivers and opening pick come with it in the box. From 1-5 difficulty level is perhaps 2 or 3. Just be careful disconnecting the ribbon cable that runs across the existing battery and take your time. Note that no paperwork or instructions are provided but there are several YouTube videos available that do a fairly decent job of explaining the installation details. Additional items you may need that appear in some if the videos that I opted to use were thin double sided sticky tape, aluminum tape, and a relatively small sheet of thin (approximately .5mm) aluminum sheet metal to make a heat dissipation sink for the underside of the battery. I was able to order everything I needed from Amazon except opted for my local hardware store for the small 4” x 10” piece of aluminum. I have only had a chance to play for a couple of hours since install so I can’t really comment on battery life or longevity over time but the battery was immediately recognized by the operating system and appears to be of good quality. I also ordered a rear case with increased cooling capacity, (more holes) and installed this at the same time but this isn’t really necessary unless you run at maximum power and frame rate most of the time. Then I could see where this would be beneficial. Additional note, there are some places on the inside of the front cover and also on the inside of the back cover where you will have to trim away some of the plastic supports but a nice pair of cutters is supplied which makes this relatively an easy task, you just may want to get some sandpaper or a scotchbright pad to smooth the rough edges down when you’re finished. I cut a metal plate of aluminum the same size as the battery and attached it to the battery with aluminum adhesive tape. It ended up on the underside of the battery between the battery and the front cover with the aluminum tape wrapped around the entire battery except for the front edge facing the circuit board when installed. Be aware that in the U.S., the manufacturer can not void your warranty just because you open the device and perhaps cut any warranty stickers, although there weren’t any in my device, but since you have to cut away some of the plastic case for this installation it may affect and possibly void your warranty. In my case, I wasn’t real concerned since I routinely repair electronics and laptops but this is something you may consider before doing this mod yourself. I’ll update this review after I’ve had some more real-life experience with battery life.

Update after 4 months: I still think this is the best upgrade I could've picked up for the Ally. I've moved my Ally over to Bazzite/SteamOS and I've had the strange battery instant shut-down most people experience. On windows, it would hang at 7% and then on SteamOS it dies around 13%. I've tested the battery to confirm that it is fully drained, so the reporting to the OS is just off no matter what, the actual capacity of the battery seems to be correct regardless. It just may be frustrating if you don't notice the low-power warnings. Still a far cry better than the stock battery. 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. 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.

Segue durando bem, muito top

Uno schifo. La batteria era difettosa e durava addirittura meno dell'originale. Al momento del reso mi è stata data un'etichetta internazionale con cui avrei dovuto anticipare io le spese di spedizione. Morale della favola? La batteria mi è stata rimborsata, dopo più di 1 mese, mentre le spese di spedizione no. Fortuna ho spedito con poste italiane (quindi 12€ di spedizione da parte mia e non più di 20€ con GLS) Venditore assolutamente sconsigliato e batteria idem
