You know how the Majesty Shop Manual is real finicky about removing
the battery or at least removing the (-) terminal even when doing a 12v/.8a
"trickle" charge, it makes me wonder how we haven't burn't out all our
bike's main fuse with all the other ways we charge the GT9B-4 and generics.
I have an AGM that can be "quick charged" to 12v/5amps in 1 hour,
and have charged at 12v/6amps for which I always take the (-) terminal
off...
I don't have a pluggin parking for Optimas and C-tek reg/tricklers,
so I still do it the manual way. Charging at 12v/1.5ah does the job for
constant chargers, and takes it to 15+ volts if you think it works better
past the 15volt limit.
I am considering an Optima charger with 20ft extension cord to drop
from my other apartment's 2nd floor, but I wonder about the Majesty Shop
Manual caution of removing the battery or at least removing the (-) terminal
in conjunction with the Optima 14.4volt limit charger.
You can do all the Volt/Amp/Watt math and say it's safe, but you
always wonder if there's something you left out which might by-pass the
40amp main fuse and burn your yamaha majesty scooter's electronics....
The "Permanently" terminal fixed Batt. terminal setup is a good
idea, since removing cowling A is a bit of a hassle after awhile, but the
rectifier has a 14.9 no-load volt limit but that's just mostly stator to
battery use, and if you wanna go with a 15 volt charge, trickle chargers
don't take that chance for that reason and take a "float" route
instead....right?
Still, sitting around for 5-6 hours for a battery to charge and
top-pu is a it of a draagggg for street parkers.
I've never heard of anything going wrong with Optima type chargers,
but that's still trickle, and a lot of AGM will allow 1 hour charges instead
of a 5 hour reg/trickle charge....so many decisions pending on one's limited
"storage" *situation*.

Correction
Should read:

but that's still trickle, and a lot of AGM will allow *5* hour charges
instead of a 1 hour reg/trickle charge....so many decisions pending on one's

Does this machine NOT have an alternator ??
If so, how about fixing it so that you don't NEED a charger at all ???
Beyond that, 12V is 12V. The battery makes a good filter for spikes.
I wouldn't worry........when you actually need a charge.

If it is anything like my dung beetle, one would have to spend an
hour at cruise to do anything... Stop&Go city traffic won't do it --
idling at a light draws the voltage down to ~11, and it takes over two
blocks for the voltmeter to rise back to 13.7 (don't turn on the low
beam, that drops the voltages 0.2V)

Sounds about right here too.......
I looked at a lot a chargers (battery tender jr/plus), with the
terminal rings, but those rings are 18" and too short for any real use on a
majesty. without adding on some length and stuff, but still a trickle
charger is not too interesting in my situation, that is I can't leave it
charging overnight like some fortunate ppl can.
