The kit includes everything you need to replace the battery: the battery, a screwdriver and matching tips, and a spatula for removing the battery. The instructions were very clear and easy to follow, though I would still look up a video for reference, as there are a few steps that are quite delicate, such as detaching the SD card slot and the battery itself. Additionally, I would definitely advise using the tray everything was sent in to separate your screws as you remove them as they come in different sizes and head shapes. I thankfully did this by group, and didn't have an issue with the screws getting mixed up. As of the battery itself, it seems to be working perfectly. My Switch now stays charged for more than a minute (it was that bad) and I can travel with my console and enjoy using it while on the go again. I can't say much about longevity of the battery as I've only just installed it, but if starts wearing out quickly, I'll update. At ~$17 for the battery, it's a small price to pay to get my console working again and much cheaper than getting an OEM Switch battery. It seems like an excellent value for what I'm getting so far. Overall, it's a great kit and something I would purchase again if my battery decides to stop working again. Review: Decent kit/semi complicated install - Seemed to work very well with 2 notes; The instructions are good until it comes to removing the old battery. It’s a really stuck in there with tape, and I felt I was risking rupturing it with how hard you have to pry to take it out. Firm, even pressure making sure not to crease it. The tool they give for removal seems suboptimal. Second, when i completed the instal and turned the machine on, the unit had a very hard time determining the battery level. Plugged in it said 100% however when I unplugged it the battery display was unstable changing every few seconds; 10%…29%…. 75%…. 100%…..15%…. 30%…..65%… and so on. The info I found online said let the battery completely die and completely recharge it to reset the sensors. This did not work the first time I did it. It did work the second time I did it. It holds a chamge as good as new now. Hope that helps. ## Features - Higher Battery Capacity : 4550mAh HAC-003 Battery Li-ion replacement battery; Upgraded hac-003 Battery voltage: 3.7V/16.8Wh, 25% higher than most batteries on the market. - Compatible with Models : This NYI high-capacity battery replacement Compatible for Nintendo Switch is very easy to install and the same size as your original HAC-003 battery.

As a note, the issue may not *actually* be the battery (it still could be), but the switch battery indicator incorrectly reading battery life incorrectly, which Nintendo has an article for (solution didn't work for me however). I tested the original NYI battery I received by playing and letting the indicator drop to 1% and seeing how long the battery lasted afterwards, and the battery lasted a total of 3 hours for Mario rpg (not too graphic intense). It's definitely no where near the original battery's life when I first got the switch, but it's better than the Nintendo battery after 8 years/SO many hours of play and changing, lasting an unpredictable 1 hr sometimes, 30 minutes others. I opted not to use the replacement I got because every time you have to change out this stuff/unplug connectors there is more chance of something breaking/bending. I am satisfied with this overall and would buy again. Amending my original review (below) because after charging and playing for about 15 minutes last night, my switch sat in sleep mode. I turned it on at lunchtime today to see if had dropped to 56%, and then when I went to turn it on after work it was completely dead. I charged it again to test it and this time I left it on for 10 minutes. Watched the battery drop rapidly to 56% then a couple minutes later it showed 4%. Ordered a replacement... It will amend my review again if i receive an actual working part. The kit had *almost* everything needed, and the instructions were very easy to follow. As others said and I had read, the adhesive on the original battery was REALLY tough to break. I watched a YouTube video that used isopropyl alcohol and a straw to drip it down the sides of the battery/tilt the switch and get underneath. The plastic tool that came in this kit was a little too thick to get under all sides of the battery, but ended up being able to pry from the bottom of the battery. After getting it out the rest was simple. The battery charged, and so far seems to hold the charge (this is less than 24 hrs after installation) so I will come back and amend my review if I have any issues, but as of now this kit/replacement gets an A+ ## Frequently Bought Together - NYI Upgraded 4550mAh HAC-003 Battery Replacement Compatible with Nintendo Switch Console Handhold HAC-001,High Capacity Internal Battery with Installation Tools Kit - ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive - Deal4GO Full Screw Set for Nintendo Switch Console Philips Head Replacement Screws (Third Party) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/430372719-nyi-upgraded-4550mah-hac-003-battery-replacement-compatible-with-nintendo](https://www.desertcart.hr/products/430372719-nyi-upgraded-4550mah-hac-003-battery-replacement-compatible-with-nintendo) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-26*
