What Are the Key Specifications of Lithium CR2025, DL2025, and E-CR2025 Batteries?
CR2025, DL2025, and E-CR2025 batteries are 20mm diameter, 2.5mm thick lithium manganese dioxide cells with 3V output. The CR2025 delivers 165–190mAh capacity, while DL2025 (Duracell) and E-CR2025 (Energizer) offer similar specs with slight variations in shelf life (5–10 years). All operate between -30°C to +60°C, ideal for watches, calculators, and IoT devices.
These batteries use lithium manganese dioxide (Li-MnO₂) chemistry, which provides stable voltage output throughout their lifespan. CR2025 variants from different manufacturers may include proprietary additives to reduce self-discharge rates. For example, Duracell’s DL2025 incorporates a carbon-based cathode coating that extends shelf life by 12-18 months compared to generic alternatives. Below is a comparison of key parameters:

Medical devices like glucose monitors often specify E-CR2025 batteries due to Energizer’s tighter quality controls. The extended temperature range (-40°C) also makes them suitable for outdoor equipment in colder climates.
How Do SB-T14 and 5003LC Batteries Compare to CR2025 Models?
SB-T14 (Toshiba) and 5003LC (Panasonic) are lithium-thionyl chloride batteries. They provide higher capacity (220–240mAh) and extended temperature ranges (-40°C to +85°C). These variants excel in industrial sensors, medical devices, and automotive systems where extreme conditions demand reliability. However, they cost 20–30% more than standard CR2025 batteries.
Lithium-thionyl chloride chemistry enables these batteries to deliver 30% higher energy density compared to Li-MnO₂ models. The 5003LC features a dual-layer seal that prevents electrolyte leakage during rapid temperature fluctuations, making it ideal for aerospace applications. Key performance differences include:
| Feature | CR2025 | SB-T14 | 5003LC |
|---|---|---|---|
| Chemistry | Li-MnO₂ | Li-SOCl₂ | Li-SOCl₂ |
| Peak Current | 15mA | 25mA | 30mA |
| Weight | 2.8g | 3.1g | 3.3g |
Automotive tire pressure sensors frequently use SB-T14 batteries due to their vibration resistance. Panasonic’s 5003LC has become the preferred choice for implantable medical devices, as its stable discharge profile ensures consistent performance over 15-year lifespans.
Which Devices Commonly Use CR2025-Type Batteries?
CR2025 batteries power devices like:
- Key fobs
- Fitness trackers
- BIOS chips
- Digital thermometers
- LED lights
Their compact size and stable voltage make them ideal for low-drain, long-term applications. DL2025 and E-CR2025 are interchangeable in most cases, though OEM manuals may specify brand-specific models for warranty compliance.
What Safety Precautions Apply to Lithium Coin Cell Batteries?
Key safety guidelines include:
- Avoid short-circuiting terminals
- Do not expose to temperatures above 85°C
- Keep away from children (swallowing risks)
- Dispose of via certified e-waste programs
Lithium-thionyl chloride variants (SB-T14/5003LC) require extra caution due to higher pressure seals and potential leakage if damaged.
Can CR2025 Batteries Be Substituted With DL2025 or E-CR2025?
Yes, DL2025 (Duracell) and E-CR2025 (Energizer) are direct replacements for CR2025. Voltage (3V) and dimensions (20×2.5mm) match exactly. However, SB-T14 and 5003LC require device compatibility checks due to different discharge curves. Always confirm terminal contact alignment when substituting.
What Environmental Impacts Do These Batteries Have?
Lithium coin cells contain toxic heavy metals like manganese dioxide. Improper disposal leads to soil/water contamination. Recycling rates remain below 15% globally. SB-T14/5003LC variants use thionyl chloride, requiring specialized recycling. Always use certified disposal services to mitigate ecological harm.
How Have Recent Innovations Improved Coin Cell Battery Tech?
Recent advancements include:
- Silicon-anode designs (15% capacity boost)
- Bio-degradable casings
- Smart batteries with charge-level indicators
Panasonic’s 5003LC now integrates NFC for inventory tracking, while Toshiba’s SB-T14 offers hybrid electrolytes for faster cold-start performance in automotive applications.
What Should Consumers Know When Buying These Batteries?
Prioritize:
- Expiration dates (longer shelf life = better)
- Brand certifications (UL, IEC)
- Temperature ratings matching device requirements
- Bulk purchase discounts for high-usage scenarios
Avoid counterfeit products by purchasing from authorized retailers. Price ranges: $1.50–$3 per unit (CR2025), $4–$6 (SB-T14/5003LC).
“Lithium coin cells are evolving beyond passive components,” says Dr. Elena Torres, a battery engineer at PowerCell Innovations. “We’re seeing demand for IoT-integrated designs with embedded diagnostics. The SB-T14’s -40°C performance is revolutionary for Arctic research tools, while the 5003LC’s NFC feature streamlines medical device maintenance. Always match the battery to the device’s peak current needs—over-specing wastes resources.”
FAQ
- Q: Are CR2025 and 2032 batteries interchangeable?
- A: No. CR2032 is thicker (3.2mm vs. 2.5mm) and has higher capacity. Using a CR2032 in a CR2025 device may damage terminals.
- Q: How long do CR2025 batteries typically last?
- A: In low-drain devices like watches, 2–5 years. High-drain uses (LED lights) reduce lifespan to 6–12 months.
- Q: Can I recharge CR2025 batteries?
- A: No. These are primary (non-rechargeable) cells. Attempting to recharge may cause leakage or explosion.
