replacing NiCd batteries

[Orange]

Can I use 300mAh (or more) instead of 30mAh NiCd battery with same
voltage (3,6v) ? Its for a computer clock.

Yes, so long as the charging circuit can supply enough current to charge it.
You may have to modify the circuit slightly (usually just a resistor) that
limits charging current to about 10% of the battery's mAH rating. It may
work as-is but charge slowly.

You can, but be aware that some types do not like continuous trickle
charging.

Check the datasheet for the battery you are using and compare with the
one you have, to make sure it is compatible.
