How Long Do Tenergy CR1220 Batteries Last?
Under normal use, a single CR1220 battery lasts 2–3 years. Actual lifespan depends on device power consumption and usage frequency. The 20-pack ensures uninterrupted replacements, while the 10-year shelf life minimizes waste.
Extended runtime can be achieved through proper storage and avoiding extreme temperatures. Devices with backlight features (e.g., digital thermometers) typically consume power faster than basic LCD watches. For optimal performance:
- Replace batteries before critical device functions fail
- Track replacement dates using manufacturer recommendations
- Test battery voltage periodically with a multimeter
How Should You Store Lithium Batteries Safely?
Store Tenergy CR1220 batteries in a cool, dry place below 25°C. Avoid humidity and direct sunlight. Keep batteries in original packaging or sealed containers to prevent contact with metal objects, which could cause short-circuiting.
Where Can You Buy Authentic Tenergy CR1220 Batteries?
Purchase directly from Tenergy’s website, Amazon, or authorized retailers like Battery Junction. Verify authenticity by checking for anti-counterfeit labels and UPC codes. Bulk purchases often include discounts, with prices ranging from $10–$15 per 20-pack.
When purchasing online, look for sellers with verified customer reviews and return policies. Physical stores like Best Buy and Office Depot typically stock these batteries in the electronics section. Beware of unusually low prices – genuine Tenergy products feature laser-etched expiration dates and precise weight (2.6 grams per battery).
