The MWD ( Measure While Drilling ) Tools battery is a special battery used to measure and detect the location and depth of underground metal pipes. The batteries provide a continuous power supply to ensure proper operation of the underground pipe detection tools. The MWD LWD Tools battery typically uses high temperaturey battery technology such as LiSOCL2 battery or LiMNO2 battery to provide wide operating temperature range, longer life and greater productivity. At the same time, this kind of battery needs to have the high security and the reliability, in order to avoid in the underground pipeline detection process the security question and the accident.

ER261020S er251020S high temperature battery have been widely used in MWD ( Measure While Drilling ) Tools. The rated voltage of ER261020S and ER251020S battery is 3.6 V, the nominal capacity current is 13000mAh more or less, the maximum continuous discharge current is 150mA, the operating temperature range is -55 ~ + 150 ° C, and the termination voltage is 2.0 v. The battery is fully sealed to ensure long life and long-lasting safety. The positive cover is welded to the housing. The glass-fiber diaphragm is used to isolate the positive and negative. The housing and cover are made of 304L stainless steel from Japan and Korea.

The ER261020S and ER251020S Battery, also known as the CC Size LiSOCL2 Battery, is larger in size and therefore has the highest capacity of any Li-socl2 Batteries. so it can provide longer working hours. besides, high-temperature ER261020S and ER251020S CC size battery has the following characteristics:

High Safety: high temperature ER261020S and ER251020S CC size battery with high temperature materials and structure, with better safety performance, can effectively prevent the battery from overheating and explosion and other dangerous situations.

Long Life: high-temperature ER261020S and ER251020S CC size batteries last longer than normal-temperature batteries, providing a longer life.

Adaptability: High Temperature ER261020S and ER251020S CC size battery can work under high temperature environment, suitable for all kinds of harsh working environment.

Environmental Protection: High Temperature ER261020S and ER251020S CC size battery used environmental protection materials, will not cause pollution to the environment.

High-temperature batteries are widely used in the oil & gas sector because of their unique characteristics:

In the oil & gas sector, ER261020S and ER251020S CC size battery is suitable for supplying power to logging and monitoring equipment, for example in combination with a generator.

In the field of medical devices, high temperature battery ER261020S and ER251020S CC size battery is suitable for wireless power supply to devices that are hot sterilized. The battery is autoclavable.
