The fire department i work for uses all kenwood products. Now our problem is we are starting to have severe problems with battery life. we use kenwood tk 3140's and tk 380's on our air packs. The 3140's we carry while on duty. Most of our batteries only last 2 hours and thats when we are not busy. The batteries are ni-mh batteries. What recommendations or options are out there? Is there a setup like the Motorola impress batteries for kenwood? we really dont want to switch to Motorola due to cost issues. Any recommendations will help us!
