Like OEM, no surprises. Highly recommended. Review: Worked w/ my New 2DS XL - Opening the N2DSXL was a real pain -- needs a 00 triwing (smaller than usual one though the big one worked for me), then you've got 2 sets of power connection plus a ribbon cable. Then getting the battery out was TOUGH! Thought I was gonna ruin the device just trying to break it from the adhesive. Finally it popped out, connected everything back together, let it charge & worked like a charm! Haven't tested it for longevity but it atleast works. Assuming the nearly 2.5x mAhs of this battery will speak for itself. ## Features - 🎮【Battery Compatible Model】: This Upgraded high capacity CTR-003 battery Compatible With Nintendo 3DS N3DS / Old 3DS / New 2DS /2DS CTR-001 MIN-CTR-001 Gaming Console,(Not for Nintendo 3DS XL New 3DS XL LL). - 🎮【High Quality Grade A Premium Battery】:This Upgraded CTR-003 Battery uses Grade A+ rated battery cells with CE and ROHS certification,ensure last over 2000+ charge cycles.

Like OEM, no surprises. Highly recommended. ### ⭐⭐⭐⭐⭐ Worked w/ my New 2DS XL *by A***F on February 22, 2024* Opening the N2DSXL was a real pain -- needs a 00 triwing (smaller than usual one though the big one worked for me), then you've got 2 sets of power connection plus a ribbon cable. Then getting the battery out was TOUGH! Thought I was gonna ruin the device just trying to break it from the adhesive. Finally it popped out, connected everything back together, let it charge & worked like a charm! Haven't tested it for longevity but it atleast works. Assuming the nearly 2.5x mAhs of this battery will speak for itself. ### ⭐ Basically, it's Fraud *by M***E on May 4, 2026* The good: • The battery fit correctly The bad: • they don't even give you the right screwdriver making installation a pain lol • Battery life is atrocious. Full benchmarking shows an average of about 4-5 hours without 3D which is comparable to the original battery, but not the ≈2.5x capacity they claim. • The listing is full of misinformation. Aside from the capacity being a lie, they also tell you to "train" it by "fully charging and discharging at least 8-10 times". I don't know if it's just bad advice or an attempt to get people to not discover how bad the battery is until it's outside the return window, but DO NOT DO THIS. This is actually REALLY bad for lithium batteries on a chemical level and is probably why you see other reviews claiming the battery starts fully dying after 6 months. • There seems to be micro controller spoofing to make you think they aren't lying, so be aware the battery will take about 4 hours to drop to 50% and then drop from 50 to 0 in about 30 minutes. • reputable 3rd party vendors mostly only produced these batteries in a 1300-2000mAh capacity, so just be wary of anything claiming more than that. Especially if it's the same price as all of the other batteries. ## Frequently Bought Together - SHENMZ CTR-003 Battery, (2025 New Version) Ultra High Capacity 3200mAh Li-ion Replacement Battery for Nintendo 3DS N3DS / Old 3DS / New 2DS /2DS CTR-001 MIN-CTR-001 Gaming Console - Dreamgear 3-Piece Stylus Pack for Nintendo 3DS - 3DS Charger, VOYEE 3DS Charger Compatible with Nintendo 3DS/ DSi/DSi XL/ 2DS/ 2DS XL/New 3DS 100-240V Wall Plug Adapter --- ## 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.sk/products/312140743-ctr-003-battery-upgrade-3200mah-high-capacity-rechargeable-li-ion](https://www.desertcart.sk/products/312140743-ctr-003-battery-upgrade-3200mah-high-capacity-rechargeable-li-ion) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-19*
