It is no secret that in the desert batteries do not last long. So much so that the first generation electric cars were not really even marketed down here after a while do to batteries failing. So yesterday was the day 3 batteries decided to take a crap. First our dump trailer quit half way up, and we had to get a new battery. Than 30 minutes later my truck would not start, and the battery was so dead it would not even jump start. Well than my drills all took a crap, and those batteries are done. 500 dollar tab on batteries in a day. Good thing we were prepared, otherwise it would have been a big hit.
