Product Overview: Why Choose Samsung 18650 29E?
The Samsung 18650 29E is a benchmark in mid-range 18650 cylindrical batteries, crafted by Samsung SDI — a world-renowned innovator in lithium-ion battery technology. Unlike low-quality generic cells, this battery features a true 2900mAh nominal capacity (minimum 2750mAh) and a 5.5A maximum continuous discharge current, offering an ideal balance of energy density and stable power output for low-to-medium power applications. Its flat-top, non-PCB design makes it effortless to assemble into custom battery packs, making it a preferred choice for B2B buyers, OEMs, retailers, and project developers across different markets.
Built with Samsung's premium INR lithium-ion chemistry, the 18650 29E boasts no memory effect, minimal self-discharge (less than 3% per month at 25°C), and a long cycle life of up to 300 cycles (maintaining 80% capacity after 300 charge-discharge cycles at 1A charge/2A discharge). This exceptional durability reduces replacement costs for your business and ensures long-lasting performance for end-users, helping you stand out in a competitive market.
