The 600mAh HAC-006 battery is a rechargeable lithium-ion cell designed for Nintendo Switch Joy-Con controllers (models HAC-015, HAC-016, and HAC-A-JCR-C0). Made by EVE Battery, it powers wireless gameplay for 20+ hours. Replacement is required when charge retention drops below 60% or physical swelling occurs. Use OEM or UL-certified third-party batteries for safety.
What Is the HAC-006 Battery and Which Devices Use It?
The HAC-006 is a 3.7V 600mAh lithium-ion battery used in Nintendo Switch Joy-Con controllers, including models HAC-015, HAC-016, and HAC-A-JCR-C0. It connects via a JST ZH 1.5mm 2-pin connector and supports wireless play for 20-30 hours per charge. This battery is cross-compatible with all Joy-Con variants released between 2017-2023.
How Long Does the HAC-006 Battery Last During Gameplay?
Original HAC-006 batteries provide 20-30 hours of continuous use depending on vibration/Rumble HD usage. Third-party alternatives typically last 15-25 hours. Battery health degrades to 70% capacity after 500 charge cycles. Nintendo recommends replacement when charge retention falls below 60% (≈12 hours runtime). Use System Settings > Controllers and Sensors to monitor battery percentages.

Actual runtime varies significantly based on usage patterns. Intensive games using HD Rumble and motion controls can reduce battery life by 40% compared to standard button-input games. Wireless interference from other devices (especially in crowded 2.4GHz environments) may decrease efficiency by 15-20%.
| Usage Scenario | Average Runtime |
|---|---|
| Basic menu navigation | 32-35 hours |
| Action games with Rumble | 18-22 hours |
| Wireless multiplayer mode | 14-16 hours |
To maximize battery lifespan, avoid complete discharges and store Joy-Cons at 40-60% charge when not in use for extended periods. The battery’s internal protection circuit will enter sleep mode after 3 months of inactivity to prevent over-discharge.

What Are the Risks of Using Non-OEM HAC-006 Batteries?
Uncertified third-party batteries risk swelling (15% reported failure rate), overheating (3% cases), and voiding Nintendo’s warranty. Look for UL 2054 certification and CE/RoHS compliance. EVE Battery’s HAC-006 replacements maintain original specs with added overcharge protection. Avoid batteries lacking temperature control circuits or using cobalt-free chemistry.
How Do You Safely Replace a Nintendo Switch Joy-Con Battery?
Replacement requires a Tri-wing Y00 screwdriver, plastic spudger, and ESD-safe workspace. Steps: 1) Remove 4 backplate screws 2) Disconnect battery connector 3) Lift adhesive-secured battery 4) Install new cell with 3M VHB tape 5) Reassemble. Calibrate via full discharge/recharge cycle. Nintendo charges $30 for official replacements; DIY kits cost $10-$20.
Why Does the HAC-006 Battery Swell and How to Prevent It?
Swelling occurs due to electrolyte decomposition (40°C+ environments), overcharging (above 4.2V), or physical damage. Prevention methods: Avoid charging while docked for >24hrs, store at 20-25°C, and limit full discharges. EVE Battery’s HAC-006 models include pressure relief vents and dual-layer separators to reduce swelling risks by 60% compared to generic cells.
What Are the Environmental Impacts of HAC-006 Battery Disposal?
Each HAC-006 contains 1.2g lithium cobalt oxide – a toxic heavy metal. Improper disposal contaminates 6m³ soil per battery. Recycle through RBRC-certified centers (Best Buy, Staples) or Nintendo’s Take-Back program. EVE Battery offers mail-in recycling with 95% material recovery rate using hydrometallurgical leaching processes.
How Does Firmware Affect HAC-006 Battery Performance?
Post-12.0.0 Switch firmware added advanced power management: 1) Reduced standby drain from 10% to 2% daily 2) Optimized vibration power allocation 3) Added battery health estimation. Third-party batteries may show “?” icons until reinitialized via System Settings. EVE cells include firmware-compatible gas gauge ICs for accurate percentage reporting.
What Makes EVE Battery’s HAC-006 Replacement Unique?
EVE’s HAC-006 features: 1) Nickel-plated steel casing (vs generic aluminum) 2) Dual CID/PTC protection circuits 3) 2% capacity variance (vs 10% in competitors) 4) Pre-applied adhesive strips with pull tabs. Testing shows 5% higher cycle life (525 vs 500 cycles) and 18% faster charge times (2.5hrs vs 3hrs) compared to OEM batteries.
The nickel-plated casing improves heat dissipation by 22% compared to standard steel enclosures, crucial for maintaining stable performance during extended gaming sessions. EVE’s dual protection circuits monitor both voltage and temperature simultaneously, reacting 0.3 seconds faster than single-circuit designs during overload scenarios.
| Specification | EVE Battery | Standard OEM |
|---|---|---|
| Charge Cycles | 525 | 500 |
| Overcharge Protection | Dual-layer | Single-layer |
| Temperature Range | -20°C to 60°C | 0°C to 45°C |
Independent testing by PowerTech Labs showed EVE’s batteries maintained 82% capacity after 300 cycles versus 73% for OEM cells under identical gaming load conditions. The pre-installed adhesive system reduces installation errors by 40% compared to separate tape solutions.
Expert Views: Industry Insights on Joy-Con Battery Technology
“The HAC-006 represents a shift towards user-replaceable controller batteries, unlike soldered cells in PS5/Xbox pads. However, its 600mAh capacity is conservative – modern LiPo tech could push 800mAh without size changes. Future iterations need graphene-enhanced anodes to address the 30% winter performance drop we see in Switch batteries.”

Conclusion
The HAC-006 battery remains critical for Nintendo Switch longevity. While replacements are straightforward, prioritizing certified cells like EVE’s ensures safety and performance. As firmware updates refine power management, users should pair hardware maintenance with software calibration for optimal Joy-Con lifespan.
FAQ
- Can I Use a Higher mAh Battery in My Joy-Con?
- No – physical space limits capacity. 600mAh is the maximum safe size. Higher claims indicate false labeling.
- Does the HAC-006 Work in Switch Pro Controllers?
- No – Pro Controllers use HAC-013 batteries with different dimensions (2mm thicker) and connector types.
- How Can I Test Battery Health Without Opening the Joy-Con?
- Navigate to System Settings > Controllers and Sensors > Update Controllers. Full charge time over 4 hours indicates degraded cells.
