Batteries are newly replaced ...Replaced the lead acid batteries in both cases. So battery life is now new.
These types of batteries only last about 1-2 years.
Only used outside on location about twice a year - very light use on the heads
These types of batteries need to be charged once a week or once every two weeks - so even when you are not using them they grow old.
The good news is that I have two of these BRONCOLOR battery cases and you can easily purchase replacement batteries online whenever you need to...the entire Broncolor Battery is $319 - but you can get the batteries that go inside these housings for like $25 each then place them into the Broncolor housing...much cheaper than going through Broncolor.
So this kit not only has two heads - but two batteries - so when out in the field you always have a backup
