Temperature Probe

For additional data and safety, many people choose to install temperature probes inside the battery banks. Regardless of the size of the battery bank, the probe should be installed on the side of one battery, below the liquid level on a battery placed in the centre of the bank. The main factor to look for is maximum temperature. The battery bank should not exceed an operating temperature of 52ºC / 125ºF.

**Mount sensor directly to side of the cell, below liquid level.  On dual-container models, the sensor should be mounted directly to the inner cell jar, not the outer case.**

Sensors should not be mounted to the top of the battery case/cell or terminal as this does not provide an accurate temperature reading of the electrolyte.
