Probably old news but I see in their latest monthly flier two new
battery chargers:

They look interesting and I would probably get one if I didn't
already
have a similar CTEK Charger. The Maintenance mode isn't explained
for
either one. You would have to play with one to find out what it does
while analyzing the output. I looked at all the comments and didn't
find
anything there either. They claim to have a reconditioning mode for
desulphating, but how it does this isn't explained...

Currently there is a $39.99 coupon for the larger version #63299.
Code
29790926 thru 10-31-2017.

I'm trying to learn to quickly determine and sometimes improve the
condition of old and second-hand batteries with my home made metered,
adjustable chargers and the HF carbon pile load. A commercial charger
that doesn't display battery voltage and charging current won't help
me.

This partly explains how, using a Harbor Freight manual charger and a
Variac:

"The CONTROL that a VARIAC affords a transformer charger battery
charger makes the most "expensive" so called smart-charger
equalization mode a Marx Brothers farce. So-called smart chargers
cannot hope to accomplish what a human being can with a VARIAC,
battery charger, digital voltmeter and an accurate hydrometer."

"Shore power" is a boating term that means electricity from the grid,
instead of the boat's generator or battery.
