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! Review: Good batter with unhelpful instructions - I bought this to extend the battery life on my OG Rog Ally after a bit annoyed having to connect to a portable battery all the time. Installation was quite easy, as they actually included all the tools you need including the snippers. The included instructios are not very helpful though, and I had to look up a few youtube videos for reference, but it was not too hard of a task. Having 2x the battery life is a game changer, it feels like my Ally is a new device again! ## Features - ⚠️CRITICAL COMPATIBILITY WARNING: Only compatible with the original White ASUS ROG Ally (2023) Series, Model RC71L / PC71L (Z1 / Z1 Extreme processors). ❌ STRICTLY NOT compatible with the Black ASUS ROG Ally X (2024, Model RC72LA) or the latest ROG Xbox Ally X (2025/2026, Model RC73XA), both of which already come with 80Wh batteries and different internal motherboard connectors. Please check your model sticker before ordering. - 74Wh MASSIVE CAPACITY UPGRADE: Upgrade your device from the stock 40Wh to an impressive 15.48V 74Wh (4780mAh). This upgraded-capacity battery delivers nearly double the play time, allowing you to run demanding AAA titles on Turbo mode longer without carrying heavy external power banks. - IMPORTANT DIY UPGRADE NOTE: Because the 74Wh capacity cell is physically thicker than the factory 40Wh battery, a minor plastic trimming on the internal support ribs of your original back cover (D-shell) is required for a secure fit. This is a dedicated mod kit, not a simple 1:1 slot-in replacement. Complete opening tools are included. - Professional-Grade Safety: Built-in multi-protection system (over-voltage/over-current/over-heat protection) safeguards your device during charging and use, and minimal self-discharge rate (<3% monthly), ensuring safe operation during intense gaming - PROFESSIONAL-GRADE SAFETY & LIFE: Equipped with an advanced intelligent Battery Management System (BMS) and premium Grade-A cells. Provides comprehensive protection against over-voltage, over-current, over-charge, and over-heating. Minimal self-discharge rate (<3% monthly) ensures stable and safe power delivery even under heavy gaming loads. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CKX3GFLH | | Antenna Location | Gaming Controller | | Battery Capacity | 4780 milliamp_hours | | Battery Cell Composition | Lithium Ion | | Battery Cell Type | Lithium Ion | | Battery Weight | 1 g | | Best Sellers Rank | #75,750 in Toys & Games ( See Top 100 in Toys & Games ) #272 in Hobby Remote & App Controlled Vehicle Batteries | | Brand | YXKC | | Compatible Phone Models | Not compatible with the Black ASUS ROG Ally X (2024, Model RC72LA) or the latest ROG Xbox Ally X (2025/2026, Model RC73XA), Only compatible with the original White ASUS ROG Ally (2023) Series, Model RC71L / PC71L (Z1 / Z1 Extreme processors) | | Customer Reviews | 4.3 out of 5 stars 50 Reviews | | Included Components | C41N2208 Battery | | Item Dimensions | 1 x 1 x 1 inches | | Manufacturer | Dongguan Mingyiyuan Electronics Co.,Ltd | | Model Name | C41N2208 | | Model Number | C41N2208 | | Number of Batteries | 1 Lithium Ion batteries required.

Installation was quite easy, as they actually included all the tools you need including the snippers. The included instructios are not very helpful though, and I had to look up a few youtube videos for reference, but it was not too hard of a task. Having 2x the battery life is a game changer, it feels like my Ally is a new device again! ### ⭐⭐⭐⭐⭐ Significantly more battery life, and fits with only minor modifications, comes with tools *by K***E on July 6, 2026* I got this to replace the battery in my old well used ROG Ally that had a rather bad original battery with only about 50% health. This is a huge improvement, probably not quite double the original battery when it was new, but at least 3x what my old worn out battery could do. Depending on what I am playing I can get something like 2 - 4+ hours of gaming with the new battery. I was a bit hesitant about having to modify the casing of my ally to fit the larger battery, but it was not bad at all. This is a mod that I think most people can do and tools are included. The included instructions are not very good, but it is easy enough to just figure it out. You just remove a few screws and pry open the ally, it comes apart pretty easy, then you just unplug and take out the old battery (it is held in by a couple of screws). Then take the included nippers and nip off whatever bits of plastic that seem like they will get int the way of the new larger battery. Mostly the bits of plastic in the middle on both the front side and the back side of the case. I just snipped down the little hollow square things on the front of the case and a few other bits, make sure to snip away some bits near the bottom middle screw hole. Just keep trying to insert the new battery and close up the case to see if you have removed enough for it to fit without excessive bulging and pressure on the battery. Then once it seemed like I got it cut down enough I added a bit of thin self adhesive foam pad to the center area just to make sure that the plastic does not cut into the battery. I used a foam pad that I had, the included bit of foam is not adhesive and not great. This battery does not screw down like the original, but it does not really seem like that matters much, as you have to make this battery fit, as long as you do not really overdo it the new battery will be such a tight fit that it is not going to move around anyway. It ended up working out well, it fit with little to no budge and it did not seem to effect the structural strength of the Ally much. The new battery did add a noticeable bit of weight, but it does not bother me when using the Ally. I was seeing people other reviews and elsewhere online doing crazy things like cutting and adding an extra aluminum plate when they did this mod, but I think that is 100% complete unnecessary. The original battery has a bit of metal frame on it and it screws down just to increase the structural strength of the device, I do not think that it has any impact on cooling or anything like that. As things like that do nothing for cooling unless they are connected to stuff with thermal paste or pads and anyway an aluminum plate is going to do basically nothing for cooling without fins to increase the surface area. So all you are doing by adding a plate is making this mod much harder by making it necessary to remove even more of the original plastic to fit the plate and the battery. An aluminum plate would not help cooling, if anything it could make it worse just by adding an extra layer that heat and air has to get around. If the plate was screwed down with the battery screws it might help structural strength, but it does not seem like it needs more structural strength to me, so doing that seems pretty pointless. I have only been using this for about a month so I cannot really comment on general battery quality, but it's working well so far. I cannot tell that the larger battery has made the Ally any hotter or anything like that and I have not had any issues with chassis strength, I have not tried really wrenching on it but it does not feel noticeably less sturdy just during normal handling. So I highly recommend this for anyone with an aging Ally battery. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/579886468-c41n2208-battery-for-asus-rog-ally-2023-rc71l-pc71l-15](https://www.desertcart.jp/products/579886468-c41n2208-battery-for-asus-rog-ally-2023-rc71l-pc71l-15) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-15*
