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

this battery is the best upgrade for your money. it functions just like the original but at almost double the battery life ! i recommend a jsaux back plate for the perfect fit. not to hard to install but make sure you watch some videos on where you need to cut.

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.

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.

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.

No instructions with install.System now cuts out at 61% battery, only having been cycled twice in 3 months, making the effective size 3/4 of the factory cells.Why did I pay close to $100 just to have a heavier unit with a SHORTER battery life?!?can't recommend.
