What's the normal cutoff time for an Ego battery? It seems most of the ones I have are getting shorter (if that's even possible) as sometimes, fresh off the charger, I'll get only 5 seconds or less and then 5 flashes on the button. Not sure if it's a battery issue, charger or what.
I've tried two different chargers and even a new battery with the same result. Starting to lose faith in my Ego's.
