Hello, I'm new here.I was hoping someone can help me identify my clark forklift so I know what the battery weight should be.All I know is it is an older clark and has #685250 stamped on the rear counterweight. The original battery has been replaced with 3- 8volt and 2-6volt heavy duty batteries.One of the 8 volt blew up. I was hoping just to replace that one with something similar but I can't find anything.Every shop wants to know what the original battery weighs.
