C41N2208 Battery for ASUS ROG Ally (2023) RC71L PC71L - 15.48V 4780mAh Gaming Handheld Replacement Battery Mod Kit, [NOT for Ally X (RC72LA) & Xbox Ally X (RC73XA)]

Couldn’t be happier my device turned on so fast it feels snappier. I love this. I love how the product bring the clippers too and a couple screws. Bits for me to work with everything was easy work wasn’t hard. Definitely would recommend for anyone who buys a preowned z1.

Install is a little off-putting especially cutting the plastic but worth it in the end. After adding and resetting my ally did notice that battery never reached 100% but did charge all the way up to 99%. The side cutters were especially nice and better than most freebies I've gotten. Price for double the battery life is a crazy good deal too.

Easy to install if you have any kind of electronic modding experience. Even if you don't, it's very straightforward and there are plenty of tutorials online and on YouTube. Install took about 15 minutes for me, but I'm pretty good with this kind of stuff, your time may vary. Initial impressions are great. Charged super fast - was completely dead upon delivery and after install was at 90% in about an hour. Battery time has improved by about 50-60% in most of the tests I've put it through, and actually improved by about double in Stardew Valley on silent mode. It's just the first day so I'll update once I have put it more time on it.

Doubles battery life depending on settings and game, to me I can’t really tell a difference in weight of console still feels same to me, holds 99% of charge after disconnecting charging and when it hits 6% it turns off you will have to cut a lot of plastic to fit the battery it has paper instructions but are not to clear so best to watch a YouTube video

After owning my ASUS ROG Ally for two years, I felt the battery life was definitely lagging, especially compared to the newer Ally X(which I also bought, because I liked the Ally so much). Deciding the time was right for an improvement, I opted for this74wh battery upgrade. Since my two-year ownership meant my warranty was already done (and this modification voids it anyway), I felt comfortable taking the plunge. The installation process itself requires some case modification (clipping away small plastic pieces), which I managed to complete in under 15 minutes. However, before installation, I took an extra step. I noticed the OEM battery had aluminum plate and tape for heat management. Being concerned about maximizing heat protection, I decided to purchase a 0.5mm aluminum plate to stick to the backside of this new battery and aluminum tape for the top side. A quick search online confirmed I wasn't the only one who felt the need to add this extra heat dissipation layer. While this is above and beyond what the instructions require, I recommend it for peace of mind. After installing the battery and my custom heat solution, I charged the device fully and put it through a rigorous drain test. The results exceeded my expectations. I was able to play games for over 3 hours straight before the device completely shut down on its own, which is a massive improvement over my degraded original battery. This battery is definitely worth the upgrade if you are comfortable taking a few minutes to clip plastic, remove the old battery, and insert the new one. The bump to 74wh makes a noticeable difference in playtime. While you don't have to follow my lead and add the aluminum plate and tape, I strongly suggest it as a measure to maintain internal heat stability. This is a highly recommended upgrade for long-term ROG Ally owners.

Easy to install, cheaper and higher capacity than the JSAUX kit. Seems I may have gotten lucky on actual capacity, we'll see how that changes in the future as it gets used more.

Great upgrade for the Ally Z1/Z1E. This kit does not come with rubber gloves, so either make sure that you ground yourself or you pick up a pair. It’s very nice that everything else is included. The included instructions are not great, so either find some online or use YouTube to guide you. If you choose to stick with the original backplate, you will need to cut away a lot of plastic. This will add some weight, but the placement of the battery will balance out nicely, putting the weight on your palms. Performance is amazing, and is well worth the price and effort. Remember that this will void your warranty. On silent TDP I now get between 5-6 hours of play time!

Worked perfectly! Instructions were very bad, but I just watched a YT video to see how it was done
