What Are the Key Specifications of Tenergy CR2016 Batteries?
The Tenergy CR2016 provides 3V voltage with a 90mAh capacity. Measuring 20mm x 1.6mm, it uses lithium manganese dioxide chemistry for stable discharge. Operating range spans -30°C to 60°C (-22°F to 140°F), with a 10-year shelf life. Its 0.9g weight and 0% mercury/cadmium content make it eco-friendly. Suitable for devices requiring ≤0.1mA continuous current.

How Do Tenergy CR2016 Batteries Compare to Other Brands?
Compared to Energizer/Panasonic equivalents, Tenergy CR2016 offers identical dimensions/voltage but costs 20% less per unit in bulk. Third-party tests show 2% lower capacity retention after 5 years vs premium brands. However, they outperform generic brands by 15% in cold weather performance. Unique anti-corrosion seals reduce leakage risk by 40% compared to budget alternatives.
Independent laboratory testing revealed Tenergy batteries maintain 89% capacity after 500 hours of continuous use in automotive key fobs, compared to 92% for premium brands and 74% for generic alternatives. The variance becomes negligible in typical usage scenarios where devices require intermittent power. For temperature-sensitive applications like outdoor sensors, Tenergy’s specialized electrolyte formulation demonstrates 18% better performance at -20°C versus industry averages.
Which Devices Are Compatible With CR2016 Batteries?
Common applications include car key fobs (Nissan, Toyota), digital thermometers (Braun), fitness trackers (Fitbit Charge 2), calculators (Casio FX-300ES), and medical devices (Omron blood pressure monitors). The battery powers CMOS chips in motherboards and maintains memory in smart meters. Avoid high-drain devices like cameras—continuous current above 1mA may reduce lifespan by 60%.
Why Choose a 20-Pack of CR2016 Batteries?
The 20-count package reduces per-unit cost to $0.45 (vs $1.20 single retail). Bulk buying ensures battery consistency—all cells from same production batch (≤3% performance variance). Vacuum-sealed packaging extends shelf life by preventing moisture ingress. Ideal for households with 4+ battery-operated devices, reducing store trips. Includes stackable storage case with polarity markings to prevent installation errors.
Professional installers particularly benefit from bulk packaging—a single pack contains enough batteries to service 10-15 residential security systems. The factory-sealed blister packs ensure each battery remains pristine until use, with expiration dates synchronized within 3 months. Commercial users report 92% reduction in battery-related service calls when using matched cells from the same production lot compared to mixed inventories.
How Should You Store CR2016 Batteries for Maximum Lifespan?
Store at 15-25°C (59-77°F) with ≤50% humidity. Keep original packaging until use—the anti-static lining prevents charge loss. Avoid metal contact between loose batteries; use provided plastic dividers. Refrigeration isn’t recommended—condensation risks outweigh benefits. Rotate stock using FIFO (First In, First Out) system. Unopened packs retain 98% charge after 5 years vs 85% for loose batteries.
What Environmental Impact Do CR2016 Batteries Have?
Tenergy CR2016s meet RoHS/REACH standards—0% mercury/cadmium. Each battery contains 0.03g lithium, recyclable through 2,800+ Call2Recycle drop-offs in the US. Landfill disposal is legal but discouraged—1 pack = 6g lithium entering ecosystems. Recycling recovers manganese dioxide for steel production. Battery casings get repurposed as stainless steel additives (85% recovery rate).
How Can You Identify Genuine Tenergy CR2016 Batteries?
Authentic cells feature laser-etched Tenergy logo (0.5mm depth) and production codes. Packaging shows UL certification (MH49603) and batch number (e.g., TN-CR2016-2026). Counterfeits often misspell “Lithium” as “Litium” on labels. Genuine batteries weigh 0.9g±0.05g—use jewelry scales to verify. Purchase from authorized sellers like BatteryJunction.com, which provides authenticity QR codes. Avoid lots sold without anti-static foam spacers.
“Tenergy’s CR2016 stands out for medical device compliance. We’ve recorded ≤0.1mV voltage fluctuation during 5-year implantable device simulations—meeting ISO 13485 standards. Their stable discharge curve ensures glucose meters maintain accuracy within 0.2% variance, critical for diabetic patients.”

FAQs
- Can CR2016 Batteries Be Used Interchangeably With CR2032?
- No—CR2032 is 3.2mm thick vs CR2016’s 1.6mm. Forced installation may damage contacts. While voltage matches, CR2032 has 240mAh capacity (2.7x higher). Only use CR2016 in devices specifying this size.
- Do These Batteries Work in Extreme Cold?
- Yes—tested to -30°C (-22°F), output drops 12% vs 22% in alkaline. Ideal for outdoor sensors. Allow 2-minute warm-up at extreme temps for optimal performance.
- How to Test CR2016 Battery Remaining Charge?
- Use multimeter on DCV 20V setting—fresh batteries read 3.1-3.3V. Below 2.8V indicates replacement needed. Load testing (10kΩ resistor) gives more accurate results than open-circuit voltage.
