Brief Introduction
The ER321270 DD Li-SOCL2 battery is our best selling product that shares similarities to the LIRDD-HTS made by Engineered Power from Canada. It is widely sold in Russia, Australia and other foreign countries.

With the diameter of 32mm and the height of 127mm, it owns the largest capacity of 27Ah among our battery cells. Based on the applicable working temperature, our non-rechargeable cell is classified into three stages, 125℃, 150℃ and 165℃. When the temperature of the directional well is low, we advised the users to use 125℃. In general, most of the customers use 150℃. If the temperature of the directional well is a little higher, the stage of165℃ is better.

Application
The Li-SOCL2 battery is widely used in the oil and gas directional drilling field, such as measurement while drilling and logging while drilling. It is used in the transceiver, electronic memory, and instruments working at high temperature.
