Every racer needs a transponder to compete on the track these days, and AMB seems to be the transponder of choice by most organizations. Problem is, they aren’t cheap! The $450 expense is equal to entry fees plus race gas for most weekends. So what are you gonna do when your rechargeable unit stops charging, or some race damage cracks your case? No reason to plunk down another $450 like the they’ll try to talk you into because nobody locally does repairs. A racing partner of mine has had good service from Transponder Services in Australia. His rechargeable unit’s battery died, and he had it replaced with a new one for about $100 including shipping. Give them a try and save some big bucks over a new one!
TIP
To prolong the life or your rechargeable transponder battery, ensure it is fully charged and allowed to run down once per month.
The type of rechargeable battery in these transponders need to be used regularly or they will die any early death.
Good luck racing!
