You are going to be the best battery life and quality when buying from TadiBrothers. The battery is made by Panasonic so it lasts and lasts, and the internal chip is made by GE.
The system can also be setup to have alerts so you are notified with an audible beep if the pressure drops below your specs, and also alerts when temperatures rise to high. The wireless transmitter, which has several mounting options, will run for up to 30 days with a full charge(cigarette adapter included) and the sensors have little button batteries that are easily replaced. You can also securely lock in these sensors onto the tires with a lock we provide in each kit. We also sell a repeater to be used in cases of interference. You may want to consider one if you are beyond 70ft. This can always be added later.
