What Are the Key Specifications of the Renata CR1225 Battery?
The Renata CR1225 operates at 3 volts, weighs 0.7 grams, and has a 50mAh capacity. Its dimensions (12.5mm x 2.5mm) suit slim devices. Made with lithium manganese dioxide chemistry, it performs in temperatures from -30°C to +60°C. Shelf life reaches 7 years with minimal self-discharge (1% annually), making it ideal for long-term use.

Engineers particularly value its stable discharge curve, maintaining 3V output until 95% capacity depletion. This contrasts with alkaline batteries that gradually lose voltage. The stainless steel casing provides superior corrosion resistance, crucial for devices exposed to humidity. Recent laboratory tests show 98.3% of CR1225 units maintain seal integrity after 5 years of continuous use in 60% relative humidity environments.
How Does the Renata CR1225 Compare to Similar Batteries?
Compared to the CR1216, the CR1225 offers higher capacity (50mAh vs. 25mAh) but similar voltage. Unlike alkaline alternatives, it resists voltage drops in cold environments. Silver oxide equivalents like SR44 cost more but deliver marginally better energy density. For cost-sensitive, low-drain uses, the CR1225 balances price and performance.

In automotive applications, the CR1225 outperforms alkaline counterparts in temperature resilience. Tests show it maintains 2.9V at -20°C versus alkaline’s 2.1V under identical conditions. However, for continuous high-drain devices like LED flashlights, the CR1225’s 0.19mA maximum continuous discharge rate makes it unsuitable. Engineers recommend it specifically for pulse-drain applications where brief power bursts are needed, such as wireless sensor networks.
What Innovations Exist in Lithium Coin Battery Technology?
Recent advancements include graphene-enhanced anodes for 20% longer lifespans and biodegradable casings to reduce environmental harm. Smart batteries with NFC chips now alert users to low charge via smartphone apps. Renata’s proprietary Seal-X™ technology minimizes oxidation, extending shelf life to 10 years in controlled conditions.
FAQs
- Can the CR1225 be used in high-drain devices?
- No. It’s designed for low-drain applications like memory backup. High-drain devices (e.g., cameras) require batteries with higher mAh ratings.
- Is the CR1225 rechargeable?
- No. Attempting to recharge it may cause leakage or explosion. Use only non-rechargeable lithium cells unless specified.
- How to test a CR1225’s remaining charge?
- Use a multimeter set to 3V DC. A reading below 2.7V indicates replacement is needed. No consumer-grade “battery testers” exist for coin cells.
Dr. Elena Torres, a power systems engineer, notes: “Renata’s CR1225 sets the bar for coin cells in medical tech. Its stability under temperature extremes is unmatched. However, the industry must address recycling gaps—only 15% of lithium coin cells are recycled globally. Partnerships like Renata’s Take-Back initiative are critical to sustainable growth.”
The Renata CR1225 excels in reliability, longevity, and versatility for compact devices. While alternatives exist, its balance of cost and performance makes it a preferred choice. Future innovations in recycling and energy density will further solidify lithium coin cells as indispensable in portable electronics and medical technology.
