Hi,

I have come across some surplus 12V to 13.8V DC-DC converters
rated for 1.7A. I.e., it will charge a 12V lead-acid at a max.
current of 1.7A if fed off of a car battery albeit it does not
have a constant-current fast charge mode and thus the last part
of the charge, where a smart charger takes the battery to 14.5 Volts
at a charge rate of C/10, is absent.  So the downside is that the
topping off of the battery is done only asymptotically (slow).

On the positive side: overcharging is impossisble and there
is no need to start the car to excute a full charge on a 12V
gelled or glassfibered lead-acid.

What I'm hoping for is to attain some bargaining power
from numbers depending on the interest in this converter.
