Reliability of Chargers - Page 4

    How long does it the charger stay in "desulfate mode"  for at 15-16
volts.

    My shop manual says to charge at 16-17 volts for 5 hours at
.8amps... it says a lot of MF AUTO Chargers may no works, and may damage the
battery....onthe other hand THAT battery said 12v/.8amps only......

    The chinese AGM battery I have now says 1 hour at 12v/4.5amps or
regular charge 12v/.8 amps 5 hours.....
    All these batteries say something different, because they are all
somewhat different IE: Wet/MF/SLA/VRAL/GEL/AGM,........But most any cheapo
batteries are just a HYBRID of that, a bit of all those, so an intelligent
charger can ping the battery to see what it can handel. it takes longer but
is the best method for most.

 the following in alt.scooter:


    I believe it will stay up to 10 hours if it "senses" improvement in
the battery. Otherwise, if no improvement sensed, it will give up with
an error indicator implying the battery is beyond recovery.

    "Normal" charge rate for many batteries is commonly Ah/10; mine uses
a 14Ah battery, and normal charge would be 10 hours at 1.4A (and a
voltage around 13.8-14.1). The small battery mode on my charger is 2A --
though there is a comment in the manual that "all" modes reduce the rate
as the battery approaches full...

    I stand corrected, I made a measurement scan, and found that the 18"
"O" rings that come with battery tenders will fit just right beneath the
"the battery" cowling"A" panel, and down the rear right signal light/fender
area.

    But for "big ass" 1 hour charging, at 12v/4.5amps the cowling"A"
panel and the (-) terminal have to come off, since they aren't fused on that
manner.

    And somebody was concerned about the desulfation mode of my charger?
At least I had it set to "small battery" (2A rate -- which is still a
tad fast for the battery size... Large battery rate is variable from 10
to 30A determined by the way the battery responds to the charger)

    I think that was voltage rate....really not much difference in most
chargers if then they borrow amps to volts and vice versa....

    Sometimes I can't really see the difference between a *constant
voltage* charger and a *constant amps* charger as they discuss in the Yamy
shop manual....they might be full of shit there at some point.

    2-3 amps is not too much for a semi quick charge on most M/C
batteries....
