I put a gel battery in my KR-2. It's worth a few extra bucks to not have to worry with venting and getting rid of the acid vapors.
Batteries explode because they generate hydrogen gas when they are charged. Look at a picture of the Hindenberg to see what hydrogen can do. I found a small company that sells a full range of gel batteries. They are most professional in their service and shipping, and their prices are competitive. Their catalog can be seen at b and c specialty.com. Jim Vance va...@clafliinwildcats.com
