Do water miser battery caps ever fit on forklift batteries?

Turns out that standard sized water miser battery caps will not fit on my forklift battery. The actual cap protrudes and hits the lead interconnects.

Wondering if their taller or extra tall caps would work on a typical forklift battery.

 Photowit? Any luck in this area?

      Did you need the tallest of the two talls?  They have:
    • Medium
    • Tall
    • Extra Tall
    I should get the extra tall to increase my chances. The demonic female goat may chew on them....

    You will  need the tallest caps to be safe.  The only thing I dont like is that it makes it harder to see the water level. ALso some caps hurt your fingers to open them some are easy. I can go 3 weeks before refilling.

    I went with the medium height caps, they work for me, I think the medium caps were a little wider helping with the visual looking for water levels. I don't know if they are also wider on the outside.


    I had a couple cap lids that were very tight when I originally installed them, but after 5 years they have loosened up a bit.

    - Assorted other systems, pieces and to many panels in the closet to not do more projects.
