Due to the high temperature requirements, we generally use wide temperature button batteries in our tyre pressure gauges. While we are at it, we would also like to introduce you to the models of wide temperature batteries. At present the commonly used models are BR2050, BR2450HT, BR1632, BR2032, etc. They can be used at temperatures from -40°C to +125°C, which is currently a record high temperature in the market. The following are the specific parameters of BR2450. 


(1) The excellent heat resistance, It can be stored at 100 maximum storage temperature for 1 hour, After returning to room temperature, it can be used normally and meet the storage temperature requirements of TPM.

(2) The great low temperature performance, at -40, the standard resistance output performance is better than the conventional battery.
