What Are the Technical Specifications of CR1216 Batteries?

The CR1216 delivers 3 volts with a nominal capacity of 25mAh. It measures 12.5mm in diameter and 1.6mm thick, weighing 0.7 grams. Constructed with lithium manganese dioxide chemistry, it operates between -30°C to +60°C. Its slim profile suits compact devices, but its lower capacity limits high-drain applications.

Which Devices Commonly Use CR1216 Batteries?

CR1216 batteries power calculators, glucometers, LED lights, and backup memory circuits. They’re ideal for low-power devices requiring stable voltage. Medical implants and fitness trackers also use them due to their reliability. Avoid using them in cameras or gadgets with high energy demands, as they’re designed for intermittent, low-current use.

These batteries excel in devices requiring minimal space and consistent power delivery. Pet microchips and electronic thermometers utilize CR1216 cells due to their ability to maintain voltage stability over years of passive use. Automotive keyless entry systems frequently rely on this battery type for its balance of compactness and adequate energy reserves. However, users should note that devices with LCD displays requiring frequent backlight activation will drain CR1216 cells faster than simpler LED indicators.

How Do CR1216 Equivalents Compare to the Original?

Equivalents like DL1216 and ECR1216 share identical voltage and dimensions but may differ in shelf life or temperature tolerance. For example, Panasonic’s CR1216 lasts up to 10 years, while off-brand versions may degrade faster. Always verify ISO certifications to ensure compatibility. Mismatched batteries risk leakage or reduced performance.

Equivalent	Shelf Life	Temperature Range
CR1216	10 years	-30°C to +60°C
DL1216	8 years	-20°C to +60°C
ECR1216	7 years	-10°C to +50°C

Why Is Voltage Consistency Critical for CR1216 Replacements?

Devices designed for 3V may malfunction if replacements exceed or fall below this threshold. Higher voltage risks circuit damage, while lower voltage causes inefficiency. Lithium-based CR1216 alternatives maintain stable output, unlike alkaline substitutes. Always check labels for “3V” and avoid mixing old/new batteries in multi-cell setups.

How Should CR1216 Batteries Be Stored for Maximum Longevity?

Store CR1216 batteries in airtight containers at 15°C–25°C. Avoid humid environments to prevent corrosion. Keep away from metals to avoid short-circuiting. Original packaging is ideal. Shelf life extends to 10 years if unopened. For installed batteries, replace them every 2–3 years, even if unused, to maintain performance.

Proper storage involves separating batteries from conductive materials using plastic dividers or individual blister packs. Refrigeration isn’t recommended despite common myths – condensation from temperature fluctuations can actually accelerate discharge rates. For bulk storage, consider silica gel packets in containers to absorb residual moisture. Manufacturers recommend rotating stock using FIFO (First In, First Out) methods to ensure optimal freshness, especially for medical devices where battery reliability is critical.

“CR1216’s niche lies in balancing compactness and stable discharge. While newer batteries offer higher capacities, the CR1216 remains irreplaceable in ultra-thin devices. Always source from reputable suppliers—counterfeit cells often use inferior separators, leading to premature failure.”

FAQs

How Long Does a CR1216 Battery Last in Continuous Use?

In devices drawing 0.1mA, CR1216 lasts ~250 hours. Higher drains (0.5mA) reduce lifespan to 50 hours. Always check device specifications for estimated battery life.

Are Rechargeable CR1216 Batteries Available?

No. CR1216 cells are single-use. Rechargeable lithium batteries require different chemistries (e.g., Li-ion) and are thicker. Attempting to recharge CR1216 may cause leaks or explosions.

Can I Use CR1216 in Place of SR1216?

Yes, if the device accepts 3V. SR1216 are silver oxide (1.55V), common in watches. Voltage mismatch may affect timekeeping accuracy. Verify device requirements first.
