Been using these 3.6V 4000mAh ER18505 Lithium Cylinder Battery for 8 months in our tire pressure monitoring. No issues whatsoever, and the build quality is noticeably better than the previous brand we used.

After comparing several suppliers, we chose these and have no regrets. The tire pressure monitoring has been running smoothly for 10 months now. Temperature performance in our hot climate has been fine.
