3. CELEWELL 6 Pack DL1/3N CR1/3N 3V Lithium Battery 170mAh【7-Year Warranty】

When I first came across the CELEWELL 6 Pack DL1/3N CR1/3N 3V Lithium Battery with a 170mAh capacity and a 7-year warranty, I was immediately intrigued by its promise of longevity and reliability. Having used various lithium batteries over time, I appreciate products that not only deliver power but also maintain their performance over extended periods without leakage or rapid degradation. CELEWELL’s specialization in battery manufacturing for over 16 years gives me confidence that this isn’t just another generic battery pack, but a thoughtfully engineered product designed for durability and high capacity.

One of the standout features that caught my attention is the actual capacity of 170mAh, which CELEWELL clearly indicates on the packaging. This transparency is refreshing because many brands either do not specify capacity or exaggerate it with virtual values, leaving buyers uncertain about what they’re actually getting. Knowing the real capacity helps me plan better for how long my devices will run before needing a replacement. For anyone relying on CR1/3N batteries—whether for cameras, flashlights, or specialized equipment like night vision instruments—having a high-capacity battery means fewer interruptions and more dependable performance.

Safety is another critical aspect where CELEWELL shines. The promise of no leakage for 5 years thanks to advanced production technology and superior materials is impressive. In my experience, leakage is one of the biggest risks that can damage expensive devices and cause inconvenience. Many off-brand batteries I’ve used had a shelf life of only 6 months to a year, often accompanied by leakage issues. CELEWELL’s battery certifications—ISO9001, UL, CE, RoHS, and UN38.3—further reassure me that these batteries meet rigorous safety and quality standards, which is essential especially if you’re using them in sensitive or high-value equipment.

The brand warranty is another factor that makes me lean towards choosing CELEWELL. A 5-year brand warranty backed by a professional research and development team signals a commitment to customer satisfaction and product reliability. Having the manufacturing and warranty dates clearly marked on each battery card is a thoughtful touch that helps me track the battery’s lifespan easily. Knowing that the company stands behind its batteries for years gives me peace of mind and reduces the risk associated with purchasing bulk batteries.

Compatibility is often a headache with specialized batteries, but CELEWELL addresses this very well. Their CR1/3N batteries are compatible with a wide range of models on the market, including CR1-3N, 1/3N, DR1/3N, and many others. This versatility means that if you have multiple devices requiring similar batteries, you can standardize on CELEWELL without worrying about fit or performance issues. The standard dimensions (diameter 10.8mm and height 11.6mm) make it easy to replace batteries in various devices without hassle.

Finally, the list of applicable devices makes it clear to me how useful these batteries can be in everyday life. From night vision instruments and invisible fence dog collars to cameras, calculators, weapon-mounted lights, and glucose monitors—this battery pack covers a broad spectrum of uses. If you rely on any of these devices, having a reliable and long-lasting power source like CELEWELL’s CR1/3N battery can enhance your device’s usability and reduce the frustration of unexpected battery failure.
