CC Size ER261020S 3.6V Lithium Battery 13000mAh Lithium Thionyl Chloride Cell
Li-SOCL2 Battery ER261020S High Temperature Battery 3.6V 13000mAh for Downhole High Temperature EPG
Forte offered the high temperature Li-SOCL2 batteries. Those batteries use different material and technique which are different from the standard batteries. High temperature batteries used special steel container and cover with high temperature structure, so Forte high temperature batteries don't have discharge, drum bulge & bottom, explosion, burning phenomenon problem. It's a safety power solution.
-
Higer & stable working voltage. Nominal voltage is 3.0V, 90% capacity output under the stable voltage.
-
Wide temperature range from -60℃ to +150℃.
-
Excellent storage life and reliability. With low self-discharge, yearly self-discharge rate ≤ 1%, stainless steel container and hermetically glass-to-metal sealing structure to make sure the battery could be stored more than 10 years in the room temperature.
- Forte batteries are environmentally friendly and pollutant fee power, it's W/O mercury,cadmium,lead and other heavy metals.

- Petroleum Industry: downhole high temperature EPG, flow meters, LWD/MWD and other downhole high temperature instruments(processing and battery racks can be done as required)
- Automobile Industry: TPMS, diesel engine cylinder monitors and so on
- Geothermy Industry: High temperature inspection instrument
- Military uses and other battery-powered devices used in high temperature
