How often do you guys check the levels in your battery.
Mine are not the sealed type and they get smart charged
every three days but I have never checked the fluid levels
If they need topping up do you use your own de-ionised water?
Having a bit of a servicing day today

once a month for a level check is fine, Just top up with your own water.
