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.

Bought for my ROG Ally Z1E. Works perfect for me so far. Charge time is significantly longer than oem. As is the case with all third party batteries, your mileage may vary but so far I'd definitely recommend this.

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.

After using it for a short time, the battery stopped charge fully. It will charge up to 60% or lower. When I drain the battery and charge it back, it will go back up, but not fully and only works once. It's very frustrating. This makes me believe that it has a BMS (battery monitoring system) type issue.

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.

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
