Battery runs Hot. I have a Ego mower, bought an extra 5.0 battery and the Ego backpack blower. One of the5.0 batteries runs hot every time I use it. So when it dies and I plug it into the charger it shows it is hot and has to cool off for about 10 minutes before it will start charging. The other 2 batteries I have do not do this. This is very frustrating because I am usually waiting for this battery to charge so I can finish my yard work. I have 2 chargers - 30 minute that came with the mower and 50 minutes that came with blower. This battery will show hot no matter what charger I try to use.
