Battery Time?
FYI,you were misinformed by the guys @ batteries plus (Battery Stuff?) because they gave you incorrect information & heres why.
Deka & Yuasa motorcycle battery mfg both state the ETX30L & GYZ32hl agm batteries for our HD touring bikes are supposed to be charged @ a max of 3-3.2 amps (respectively) & not the considerably higher (by approx 40-45%) charge rate of 5amps you were told.
Max charge rate of 3.2amps is actually printed on the case of the Yuasa GYZ32HL battery i installed in my HD,i guess the phone guy @ Batteries Plus know's something Yuasa & Deka doesnt.
Now will using a 5amp charger damage either of those batteries after a few uses,very not likely.
But would long term use of a 5amp charge rate maint type charger/tender being used on those batteries be the proper/best choice when mult mfg's rec using a max of 3-3.2amps on the battery they mfg?
NO,it would not be the best choice.
And over time using an approx 40-45% higher amp charge rate then the battery mfg rec's could reduce srvc life a bit due to fact AGM batteries by design having less electrolyte in them making them more sensitive to drying out when charged with too high of a charge rate/too many amps.
But it's not as much of an issue when talking older gen std lead acid battery tech thats fully flooded using considerably more electrolyte/acid making that type battery much less likely to have issues with drying out & warping plates when charged at higher amp rate.
Happy Motoring.

Sorry dude.
The people I talked to was Odyssey Batteries.
And their batteries has Virgin lead.
They perfer their own battery chargers.
Call them, that is what I did.
http://www.odysseybattery.com/
Know people that has had a Odyssey battery for over 10 yrs.
mine is 5 yrs old now.

WHAT ARE YOU TALKING ABOUT?
YOU GOT THE WRONG PERSON/POST.
I DIDNT MAKE ANY REF TO ODYSSEY BATTERIES , HOW LONG THEY LAST,VIRGIN LEAD VS USING RECYCLED LEAD WHEN MFG THE BATTERY & OR USING ANY SPECIFIC BATTERY CHARGER EITHER.

As for Odyssey batteries, the one I had lasted a couple of years then phut!
IMPURITIES BOILED/FILTERED OUT...
his point was that the products they are getting from a country south of the US have NOT been sufficiently processed to ensure all the impurities are out during the melting/smelting process, leaving a metal product that is not pure and not as effective as they should be... that's the point.
No argument what so ever with the process you described which produces a 'recycled' product that cannot be differentiated from the original metal in quality or characteristics. Thanks for your clarification.
Cheers
And, since the testing procedures were then (and are now, as far as I know) equal to the best in the world, your thinking is WRONG.
Once the lead is smelted and purified to the battery manufacturer's standard, it makes no difference to the battery what the origin of the material is.
Your maintenance is more important to the life of the battery.
My battery is still the original from 2009. I'll replace it in the spring just because I don't want to be stranded.

Yea there is.
Virgin lead charges faster and holds a charge longer.
And Virgin lead batteries last longer.

True, it's good idea to keep a std lead acid or AGM battery at or very close to it's full charge voltage at all times.
And keep this in mind ,the fact is newer gen lead acid AGM bike batteries BY DESIGN not only have considerably less voltage loss over time without charging then older gen std lead acid batteries do but AGM's are also considerably less sensitive / likely to sulfate too.
1 More time.
The point you guys are missing,overlooking & or are misunderstanding is when keeping / holding a newer gen lead acid AGM bike battery (that by design also has considerably less electrolyte in it) @ a consistent 13.1-13.2v's (on a 12.8v full charge voltage) while in it's lower charge rate float mode for days ,wks or even longer thats a situation that in some cases leads to drying out & warping plates leading to premature battery failure in 1-1.5-2yrs.
I have seen that happen more then just a couple times over the yrs mult times over the 4.5+ decades wrenching bikes & cars for not only my self but other people i maintain bikes and classic muscle cars yrly too.
Again,its some (not all) maint chargers that can paoss do that so chk check battery voltage on your bike after its been in float mode charge for 4-5 days or over a wk to see what voltage the batt's being held at.
And if battery that has full charge v's of approx 12.8v's is being held 13v's or higher is when i rec not leaving it on the battery any more then 24hrs post reaching full charge voltage to not reduce it's srv'c life.
There is no reason to hold a battery that has full charge v's of 12.8v's or so continuously @ or above 13v's in the 13.1-13.2v's range like i saw 1st hand when testing.
Why the battery charger mfg's dont design their maint/float chargers to hold std lead acid or newer gen lead acid AGM bike batteries that have an approx 12.8v full charge voltage @ a consistent 12.9-12.95v's i am not sure but would be a good place to be IMHO.
We have the tech today to reliably hold a bike battery to a max of 12.9v's (12.95v's Max!) while in float mode tops & don't know why they dont do that..
And the couple of float chargers i tested that were keeping the battery @ 13.1-13.2v's would consistent hold the battery at that voltage for days on end with batt voltage neved dropping below 13.1-13.2v's until i remove the charges in float mode from the battery.
Then the battery would come down from the 13.1-13.2v's it was at for days on end when i removed either of the the chargers i tested from the battery that were both still in float mode @ the time down to 12.9ish v's in 3-4-5hrs & then would stabilize at 12.8-12.85v's post aprox 7-9hrs.
So that verified the chargers in float mode were both in fact consistently holding the battery @ 13.1-13.2v's not letting that voltage drop for days on end till i removed them from the battery.
So point is over time /1-1.5-2yrs of a maint/float charger holding a std or AGM lead acid bike battery @ 13.1-13.2v's over time can dry out enough electrolyte from the battery & or plates warping them,damaging the battery leading to premature failure.

Yuasa 1.5 Amp Automatic
The larger of the two Yuasa maintainers is unique within this group. Its billed as a five-stage charger/maintainer. When first connected and plugged in, it flashes lights to signify correct polarity and the presence of AC power. The unit then applies a series of pulsing currents while monitoring the rate of voltage increase and decay. The electronics within the charger use the resulting information to determine whether the battery is serviceable. Assuming the answer is affirmative, the charger then applies a 1.5 amp pulsing current to bring the battery to near gassing voltage. The current at 14.0 volts was still up at 1.4 amps, but 14.1 volts triggered the device into absorption mode.
At 14.1 volts, the big Yuasa switched to a 0.9 amp pulsed charge rate while maintaining the abrupt pulse shape. It tapered the charge rate as the battery approached 14.3 volts, finally holding the battery at 14.3 while the absorption rate dropped to 0.3 amps. The switching from 1.4 amp constant current charge to a tapering current constant voltage charge of significant duration clearly indicated that this product does indeed employ a multi-mode charging process.
During float, the Yuasa 1.5 maintained a 10-milliamp current and kept the battery at 13.29 volts. Applying a 4-amp load to the battery caused the charger to immediately go back into charge mode. As a fifth and final stage, this unit claims to shut down, then re-start the charging process every 28 days. This final stage of operation exercises the battery, providing additional protection from sulfation damage for batteries stored for extended periods.
I still have an old Odyssey in my SUV that is over 10 years old--the 'good' one and the tech said I was lucky to have it... I do have to keep it on a tender because it's on its last legs and I hate to see it go...
I keep both bikes on a tender always... batteries like it.... Good luck.
