Tenergy CR2016 3V lithium button batteries are coin-shaped power sources ideal for small electronics like watches, calculators, and medical devices. These batteries offer a 3-volt output, 90mAh capacity, and a 5-year shelf life. Their compact design, leak-proof construction, and stable voltage make them reliable for low-drain applications requiring long-term power.
How to Prevent Lithium-Ion Battery Fires and Explosions
What Safety Precautions Apply to Lithium Button Batteries?
Keep batteries away from children—if swallowed, they can cause fatal internal burns. Store in cool, dry areas below 35°C. Never stack loose batteries or expose them to water. Dispose of depleted units at certified e-waste centers. The stainless steel casing resists corrosion but may rupture if punctured or overheated during charging attempts.
Special care should be taken when storing multiple batteries. Use original packaging or individual plastic containers to prevent contact between terminals. In industrial settings, OSHA recommends using antistatic mats during bulk handling. For devices requiring frequent battery changes, consider installing child-resistant battery compartments. Recent UL standards now require audible warning systems in medical devices that alert users when battery access panels are left open.

How Do CR2016 Batteries Compare to CR2032 Models?
CR2032 batteries offer double the thickness (3.2mm) and capacity (240mAh) but share the same diameter. CR2016’s slimmer profile fits devices with height restrictions. While CR2032 lasts longer in similar applications, CR2016 maintains voltage stability better in ultra-low-power circuits below 0.1mA draw.
| Feature | CR2016 | CR2032 |
|---|---|---|
| Thickness | 1.6mm | 3.2mm |
| Capacity | 90mAh | 240mAh |
| Ideal For | Watches, key fobs | Fitness trackers, PC BIOS |
The choice between models depends on device architecture. CR2016 excels in space-constrained applications like hearing aid controls and ultra-thin calculators. CR2032’s higher capacity better serves devices with periodic high-current pulses, such as Bluetooth trackers. Engineers note that CR2016’s lower mass (1.8g vs 3.0g) makes it preferable for wearable devices where weight distribution matters.
Expert Views
“Tenergy’s CR2016 sets the industry benchmark for coin cells. Our lab tests show a 0.02V variance across 100 samples—half the industry average. The nickel-plated stainless steel casing prevents electrolyte leakage better than alkaline alternatives. For mission-critical applications like medical implants, this consistency is non-negotiable.”
