FAQs

Sealed Energy lithium coin cell batteries are engineered for long-lasting performance. Generally, you can expect our batteries to last anywhere from 3 to 10 years, sometimes even longer. The exact lifespan, however, largely depends on a few key factors:

• The Device’s Power Consumption: Devices that require constant or high-power draws (like certain smart home sensors or medical devices with continuous monitoring) will naturally deplete the battery faster than low-power devices (like a remote control or a simple clock).
• Usage Frequency: A device used daily will consume more power than one used intermittently.
• Environmental Conditions: Extreme temperatures (very hot or very cold) can impact battery life, although our batteries are designed to perform reliably across a wide range.
• Battery Chemistry and Quality: Our premium lithium chemistry and stringent manufacturing processes contribute significantly to the extended lifespan and reliable performance of Sealed Energy batteries compared to standard alternatives.

We design our batteries for optimal endurance, ensuring your devices stay powered for their intended purpose, reducing the need for frequent replacements.

No, Sealed Energy lithium coin cells are primary batteries and are not designed to be recharged. Attempting to recharge these batteries can be extremely dangerous, leading to overheating, leakage, rupture, or even fire. Our batteries are engineered for single-use applications, providing a stable and reliable power source until their energy is fully depleted.

Yes, when used as intended within a device, our coin cell batteries are safe. However, it is crucial to understand that when out of packaging, coin cells can pose a significant choking hazard for small children. Their small, round shape makes them easy to swallow.

At Sealed Energy, child safety is a top priority. We are proud to state that our coin cells are enclosed in child-safe packaging in strict accordance with Reese’s Law (16 CFR 1700.15 standard). This packaging is designed to be difficult for small children to open, minimizing accidental access to the batteries.

Always keep batteries out of reach of children. If a child swallows a coin cell battery, seek immediate medical attention. Do not induce vomiting.

Proper disposal of lithium batteries, including coin cells, is vital for environmental protection and safety. Lithium batteries are often considered hazardous waste and should NEVER be thrown into household trash or recycling bins. This is due to their chemical composition, which can pose environmental risks or even fire hazards if improperly handled, especially if damaged or short-circuited.

To dispose of your used Sealed Energy coin cells properly:

1. Check Local Regulations: Always consult your local municipality’s waste management guidelines or recycling centers. Regulations vary by region.
2. Look for Battery Recycling Programs: Many retail stores (electronics stores, hardware stores, grocery stores) offer battery recycling drop-off points. You can also search online for dedicated battery recycling facilities in your area.
    
3. Tape the Terminals: To prevent short circuits during storage or transport, it’s a good practice to place clear tape over both sides (positive and negative terminals) of the battery before dropping it off for recycling.
4. Do Not Incinerate: Never burn batteries, as this can lead to explosions.

By properly recycling your used coin cells, you contribute to a safer environment and the responsible management of valuable materials.

Yes, Sealed Energy coin cells are designed for excellent shelf life and can be stored for long periods, typically several years, before use. This is due to their very low self-discharge rate, meaning they slowly lose charge over time, even when not in a device.

To maximize their storage life and ensure optimal performance when ready for use, follow these recommendations:

• Store in Original Packaging: Keep batteries in their sealed, original packaging until needed to protect them from moisture and accidental short-circuiting.
• Cool, Dry Place: Store batteries in a cool, dry environment, ideally at room temperature (around 20-25°C or 68-77°F).
• Avoid Extreme Temperatures: Do not store batteries in very hot or very cold conditions (e.g., direct sunlight, near heaters, or in a refrigerator/freezer). Extreme temperatures can accelerate self-discharge and potentially reduce overall capacity.
   
• Keep Away from Metal Objects: Ensure batteries are not stored loosely with other metal objects (like coins or keys) that could cause a short circuit.

Following these storage guidelines will help ensure your Sealed Energy coin cells retain their power and are ready to deliver reliable performance when you need them most.
