after 18 hours if charging they are at 12,54 volts,

any thoughts ?


Voltage is almost meaningless. That seems a tad low, but it depends
on a number of subtle factors. Also, what was the charge rate? You
mentioned trickle charging, so they might not be fulling charged yet.

You need to charge them with a proper charger, then do some sort of
load test - that's the only thing you can do to determine the health.
Someone suggested a high intensity lamp, you could also use an
inverter with a heating appliance. Or you could take them to a
friendly battery shop or garage that might have a proper load tester.
