Looking for a weight estimate for this forklift battery.

Just a guess >> But I am thinking Between 700 and 750 for the Batteries
Based on looks like 6 X 3 = 18 batteries wired in series
The average I use for a car battery is 35 >> Bumping that to 40 as they look taller, but also smaller in rectangle size (less square inches for the top area)
40 X 18 = 720

Please come back and let us know the correct answer when you Ca$H it in
Thanks

Thanks guys I appreciate the help. It's actually coming up on auction soon along with some other stuff I want to get, so I thought might as well see if I can get this as well!

If I win, I'll let you know of the weight!
