We are having problems with Motorola MDT's drawing down the batteries in our Battalion Chief's Suburbans. What do other departments do to prevent this? We are going to install automatic switches that cut the power before it drops too low to start the vehicle. While this is an improvement, this will still cause us to have to power up the MDT and complete the sign in process if it shuts down. Time consuming and not something that can be done driving down the road. How do others handle this?
