Re: Bob Smiley's question.

Bob, a battery keep-alive or topping charger isn't necessarily rated at a
specific output current. Rather, it should respond to the battery terminal
voltage by automatically reducing the charge current to near zero when the
voltage indicates full charge. It could start at several amperes as long as
it drops as required as the battery voltage comes up to full charge.

The only chargers acceptable to leaving one connected all the time are the
so called automatic topping chargers. Forcing a continuous 200 ma into a
fully charged battery, even the recombinant gas types, is likely to shorten
it's life - though different manufacturers units can exhibit very different
response to such conditions. Batteries from different mfg's can and do have
significantly different characteristics - some are just more tolerant than
others - I'm told that it's mainly due to some technician in the factory
that knows just when to spit in the brew that makes all the difference!
