A lot of modern batteries,and l think the op has said his is are described

They dont have nice threaded filler caps easily accessible, what filling
caps there are need a cover prised off to reach and in doing so the
integrity of that cover is destroyed and with it the mechanism for holding
the caps in place as they are not always threaded.
So you need to bodge up a way to fix it all back together again and not
leak in use.
May be worth doing if you are stuck in some remote place in Africa and have
no alternative but hardly worth the effort where you can purchase a battery
for the price of few pints and a couple of posh burgers down the pub.

'Sealed' lead acid batteries are never sealed. How exactly are they going
to leak when they're open *at the top* just like lead acids have always been?


The filler caps on the old style batteries screwed in firmly, on a so
called sealed battery the equivalent caps are often just pushed in and the
mechanism for holding them tightly is part of the battery top installed at
time of manufacture and not intended to be removed again ,It is that part
that you will have had to prise off to get access to the filler caps and in

which is fairly easy

doing so may well have damaged that so it can no longer hold push fit caps
tightly.

it doesn't need to

The electrolyte may be happy when the vehicle is bowling along a smooth
motorway but bounce in and out of some the poor surfaces on some roads and
it will start to splash out.

I've carried enough liquid in vehicles to know that's unrealistic. Even without the rubber or plastic covers it would work. If you're the sort that climbs up mountainsides at over 45 degrees to the horizontal and literally bounces the car going down, then I wouldn't.
