Been a long time since I bought or used a deep cycle wet battery
. But in the past I recall they were filled to the bottom of the "tube" going down from each cell cap.
Just bought a group 27 and all the cells appear even but the are all about 3/16 to maybe a 1/4 inch below those tubes.
I was about to go grab some distilled water and then got to thinking maybe I'm not remembering correctly on how full the cells should be.
Anyone know how far below the caps a conventional wet battery
should be filled?
