12V is not the right trickle voltage. I forget what it is, but it's a little
above a fully-charged battery, which will actually register something just a
touch higher than 12.6 V at rest - and having rested a while since being on
the charger.

I have several battery links posted at
www.ctlow.ca/Trojan26/index.html#battery. One of them is www.batteryfaq.org.
It's a complicated topic.

I have a question I've pondered for a while ..........

On a trickle charger, if you were to connect an IC
that limits the voltage to 12 Volts only ( LM12 ) could you
leave the charger on indefinately without damage to the battery?

================================================

What we are really talking about here is the so called "float" voltage
where a battery can be kept at full charge while under no load. Float
voltage is normally specified in the range of 13.2 to 13.4 volts
depending on temperature and battery type. Anything higher will boil
off the battery over time.
