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

Been using this for a few months now in my ROG Ally and it’s works flawlessly! Almost double the battery life actually makes it feel like a true handheld

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

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.

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.
