Yes. You have a small charger, not even a trickle charger. What you
really want is a "float" charger. This is a lower voltage output,
accurately regulated, and it really ought to be temperature sensitive
too.

Using one of these very simple transfomer / diode chargers permanently
is definitley a bad idea - their voltage is high enough to be distinctly
harmful long-term.
