Stored my Harley last fall starting mid November. I put a Schaller 1.5
amp battery maintainer on it at that time. Today I fired it up and it
turned over like it would while in use. I've owned the bike since 2002
when I bought it new. The battery is a gel-cell. This is the first time
I've used the maintainer and was pleasantly surprised that it did its
job. Previously I crossed my fingers as after being parked for 5 or 6
months it always turned over barely enough to start.
End of story.
A battery maintainer works better than a trickle charger. Leaving a
battery on a trickle charge causes sulfation and deterioration, which
also happens if it sits months without charging. A battery maintainer
switches on and off as needed.
Gel cells have slower self-discharge than conventional motorcycle
batteries, so the OP might have gotten a good start without the
maintainer. The maintainer is still a good idea.
Fifteen years ago, I used a zener and a couple of other diodes and some
resistors to make a $2 meter movement swing full range between 11 and 15
V. I keep it below my dashboard. Depending on what the meter says, I
top off my battery several times a year using a voltage-regulated
(automatic) charger. It's a two-year battery going strong since 2002.

That and also a maintainer will NOT charge a dead battery. Tried that on
my 2004 Kawasaki Vulcan. I thought incorrectly that 1.5 amps would
trickle charge the battery. It wasn't completely dead either. Just enough
where it would not turn the motor over completely. The Schauer (not
Shaller as previously stated) has an indicator LED. Yellow when charging
and green when charged. The indicator changed to green on the Vulcan
battery but it wasn't enough to turn it over more that a couple
revolutions. That was surprising. I jump started the Vulcan and road it
for 50 miles recharging the battery and never had a problem with it
My "Bell" brand "The Juicer" battery charger maintainer is rated at only
750mA and it charges not only a wave runner battery, but it will do a
half dead car battery too, just takes a while. Red led when charging,
turns green when in "storage" mode.

Then it's a charger/maintainer :) One would assume the Schauer maintainer
would actually charge a "half dead" motorcycle battery but it sure didn't
in my case even though the indicator showed it went from yellow to green.
I used it in the winter of 2009-2010 to plug into my SUV battery which was
an Autozone battery. The advertised CCA was vastly underrated as when the
temp dropped into the single digits the motor cranked very slowly barely
starting. And it was only two years old. Using the Schauer overnight did
improve the cold cranking speed. In 2010 I moved up to an Autozone 1000
CCA battery and that solved the problem. I was a little leery leaving
the maintainer on the Harley for 4 full months but it was a pleasant
surprise to fire it up two days ago fully charged.
In a waverunner I have a small motorcycle size battery and this thing
won't die. Normally they only last 2 or 3 years, this thing is 5 years
old so I wasn't worried about maintaining it over the winter. Checked
it two days ago and it was dead, about as dead as they get. For the
hell of it I put on a 7 amp charger, the amp gauge didn't even move.
Then forgot about it and it was on for about 10 hours and amp gauge was
at 7. It was very warm and bubbling away. It cranked the motor like
new. Two days later it still cranks like new. If I would have taken
care of it, it probably would have lasted 10 years! I can't trust it
out in the lake so I'll get a new one this year, I'll try to hunt down
the same brand again, I don't know it off hand.

Buy a Harley battery. They are completely sealed and a jell cell. And
they are known to last well beyond 10 years. Plus being a jell cell they
have a deeper discharge cycle and won't loose as much capacity if
completely discharged. I also own a 1981 Honda CB750F I purchased new in
1982. I've replaced the battery in that thing maybe 8 times and there is
nothing wrong with the charging system. I'm sure if I had a maintainer on
it I would have gotten double the life of each battery as they seem to
sulfidate easily over the 5 months not in use. And the bikes are both
stored in a temperature controlled garage temps never getting lower than
50F. I can't afford a dead battery either seeing neither the Honda or
Harley have kick starts and are almost impossible to push to pop the
clutch unless you're on a hill or enlist the help of a couple willing
