Battery lost power, charging did not good. Replaced with new battery and did one mowing and everything was fine. Then 4 days later was mowing and 3/4 way through my second mowing of 2 acres, the battery died, reminder this is a new battery doing the same as old battery. Put charger on it and after a few minutes it was ready and tried to start it and it started right away, but as soon as i removed the charger it died again. This is the same as it was doing with the old battery, as soon as i pulled the charger it died, so that kind of rules out a battery problem. i have no idea what could be causing this problem, or what is killing the battery or if it has anything to do with the battery per say. Any help would be much appreciated. Thanks for any help i can get.
