  • Everything You Need to Replace Your Switch Battery - Easy to Install, Clear Instructions Everything You Need to Replace Your Switch Battery - Easy to Install, Clear Instructions
The NYI Battery Replacement for the Nintendo Switch is a great option if your Switch battery farts out and you need a reliable replacement. 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. ... show more

  • 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. ... show more

  • Was able to get it changed out in 45 mins but...
Amending once more after receiving replacement. 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+ ... show more

  • It’s fine I guess
The kit it self is great. Great quality tools and instructions was easy to replace battery. The new battery sucks tho. My switch is constantly on the charger just like before the replacement battery. I’m pretty disappointed honestly I was really excited for a new and improved battery so I could stay off the charger for a couple hours. I would love for them to send me a new battery to try out at this point because it seems like they gave me their worst one. ... show more

  • Battery does not last, about the same as the 8 year old original battery I replaced
2 things, the new battery had the same battery life as my 8 year old original battery, effectively making this replacement pointless and a waste of money. After charging up, I left it on standby overnight and the Switch went from 100% to 20% in the span of 8 hours on standby. The kit itself is also incomplete, if you are replacing the Battery, highly recommend replacing the thermal paste on the heat pipe, the kit makes no mention of this, but I discovered the thermal paste when I opened up the switch to replace the battery. I then ordered new thermal paste and put the switch back together with the new battery. Luckily the thermal paste being old did not effect the cooling but I will still replace the thermal paste as I discovered my switch body had several damaged screw mounts so I also ordered a new switch body, will also try a different battery and see what the results are. The battery is a PITA to remove, but that has nothing to do with the product itself. The tools provided did make the installation easy. ... show more

  • Great kit
I used this kit with ease, I recommend having some rubbing alcohol to unstick your old battery as the adhesive is very strong. The new battery is holding up well. Fun little project honestly, I enjoy fixing things myself, I would use this kit again if needed

  • no battery life?
It seems battery life is utterly crap after reinstalling it. But for me, I was able to resolve the issue after battery cycling. It seems to be doing alright on it but I'm going to keep an eye on it.

  • Excellent product with everything included for easy replacement
The battery works perfectly on my Nintendo Switch (1st Gen). Also, the instructions provided to replace the battery were so easy to follow. They provide everything you need, mini screw driver (metal) with the interchangeable heads and a plastic spatula to help with removing the battery.
