Product Description:

The Lithium Battery Cell, also known as the Li-SOCl2 Battery, stands as a high-performance power source suitable for a wide range of applications. This Primary battery is engineered to offer a reliable and stable source of energy for devices requiring long-term, uninterrupted power. With a Nominal Voltage of 3.6V, it is designed to deliver consistent performance, powering a variety of electronic devices with efficiency and precision.

One of the most notable features of this Lithium Battery Cell is its exceptional working temperature range. Capable of operating in extreme conditions, the battery maintains functionality at temperatures as low as -60℃ (-76℉) and as high as 85℃ (185℉). This resilience against temperature variations makes it an ideal choice for applications subjected to harsh environmental conditions, including outdoor equipment, industrial machines, and high-temperature environments.

In terms of storage, the Lithium Battery Cell exhibits excellent stability with a recommended Storage Temperature of a maximum of 30℃. This ensures that, when not in use, the battery retains its charge without significant degradation of its components. This aspect is particularly important for devices that may go extended periods without use but must perform at a moment's notice. The well-regulated storage temperature range aids in preserving the battery's integrity and prolonging its usable life.

A defining characteristic of the Lithium Battery Cell is its Long shelf life. With a remarkable warranty of 10 Years, the battery assures users of its longevity and reliability. This long shelf life is attributed to its Li-SOCI2 chemistry, which is known for low self-discharge rates. The low discharge rate means that the battery can be stored for long periods without a considerable loss of capacity, making it a go-to choice for critical applications where battery replacement can be difficult or inconvenient.

The Lithium Battery Cell is designed as a Primary battery, which means that it is intended for single-use and is not rechargeable. This feature allows for a higher energy density and a longer shelf life compared to rechargeable alternatives. It is a perfect match for applications where recharging is not practical or possible, such as in remote monitoring equipment, memory backup systems, and emergency location transmitters.

Furthermore, the robust build and the use of advanced materials in the Lithium Battery Cell ensure it delivers a reliable performance without the risk of leakage or rupture, which can be a concern with less advanced battery technologies. Its construction is also environmentally friendly, reducing the impact on the planet while still providing the power and endurance required by modern electronic devices.

In summary, the Lithium Battery Cell is an exceptional choice for anyone in need of a Long shelf life battery with the resilience to withstand extreme temperatures. Its impressive 10-year warranty, 3.6V Nominal Voltage, and sturdy Li-SOCI2 chemistry make it a top contender in the realm of Primary batteries. Whether you're powering critical medical devices, security systems, or data loggers, this battery is engineered to provide dependable energy without the need for frequent replacement or maintenance. For those seeking a robust and enduring power source, the Lithium Battery Cell offers the perfect blend of reliability, performance, and peace of mind.
