This from the Shorai site,5th question down,as you will see it will tell you your junior works.The link to Phat that Davej re-posted is exactly what you will find at the ballistic site. You cannot use a desulfation mode on any lithium battery,Hope this is what you are trying to explain Scottw, Shorai or Ballistic. so you see Ace ( you got a handle on that, jr it's a great charger,) you're safe.

Sulfation takes place from the day the acid is added to the lead.
http://en.wikipedia.org/wiki/Desulfation
Notice the "Key" words here, you can't stop it, and only reverse partially.
As to the charger,this is a long and boring video from the Ballistic site. http://www.youtube.com/watch?v=F_lSfw4q2B0&feature=endscreen&NR=1
On the other hand it does explain why you might want it. Remember as the 2 manufactures explain the batteries come "balanced from the factory". So why re-balance? Our charging systems don't.I see why the Shorai is more expensive http://en.wikipedia.org/wiki/LiFePO4 as to the http://en.wikipedia.org/wiki/Lithium-ion_battery it will last longer.
In time you will not be able to buy a lead acid battery.You young guys will have to change,
As I said in my last post on this subject, enjoy and read, the lead acid battery is a Dinosaur.Lead is bad,( It's banned in the Great lakes for fishing sinkers) we don't care!Let the kids and Grand Kids worry about cleaning it up OK now tell me why, other than the cost saving,

==================================================
Well no need to get snotty with this crap like this " you got a handle on that, jr)"
Chk this out directly from the Lith-ion/AGM/Dry Cell batt mfg's when it comes to charging some i think you have already seen but wont hurt to see/read again.
1st) up,lith-ion:
This stamtmenet from the lit-ion batt mfg(Shorai) "
you may NOT use a charger/tender if it has an automatic "desulfation mode", which cannot be turned off."Is one of the things i was reffering too because some chargers/tenders mfg today do have this sulfation mode thats damaging to these new gen lith-ion batteries.
So like i said the batt mfg said you really can't use just any charger/tender meaning if it has desulfation mode that some chargeres/tenders have it should not be used.
The lith-ion batt mfg also says " the best possible charger/tender for Shorai LFX is the SHO-BMS01, which will be released on about March 15th 2011. It uses the 5-pin BMS port in the LFX batteries, in order to monitor, diagnose, and balance the individual cells during charge. And it also has an optimized storage mode that will give the longest possible service life to your LFX."
2nd) Now,for AGM batteries,heres what Deka batt mfg had to say about charging AGM batteries.
CHARGING
In the rare occurrence that an AGM battery needs to be
charged outside of the vehicle’s charging system, there are
chargers that can be used.
Many common battery chargers are not fully compatible
with AGM batteries, however; they
will not ruin the battery
if used only once or twice over the battery’s lifetime.Adversely, not all chargers are safe and can produce severe battery damage in only a few hours of use.
Now the above statement from the batt mfg " if used only once or twice over the battery’s lifetime" is an important stament that if any std charger/tender is used more then only 1 or 2x over this batteries 4-5-6 yr lifetime it will damage it ,that to me is significant that if you use a std chrger 1-2x you can damage the battery and people need to know this.
3rd),Now for Odyssey dry cell battery from thier site.
There is a lit of charger they have on thier site that are ok BUT
basically all Schumacher chargers/tenders mfg today cant be used per this batt mfg and schumacher a mfg a lot of tenders,i have one .
Heres what Odyssey said abou that tender.
This charger/tender not mfg anymore can be used for tricle charging only,SC-2500A
(no longer inproduction)
Battery Mart ACC-1206WB
ONLY for trickle charging PC310 to PC680; DO NOT use for
battery cycling
Then they say.
No other chargers manufactured by Schumacher
have been tested and approved by ODYSSEY
But for all the 7-8 chargers/tenders they rec they have footnotes with all sorts of limitations -settings your to use on the charger & if you dont thier rec charger setting/mode their rec charger /tender could still damage the battery.
So even though your using thier rec charger/tender for thier dry cell batt if you dint set it to proper mode it can still damage the battery if you dont pay attention to these details.
Hers a few examples of those footnotes for eash charger.
* ONLY for trickle charging PC310 to PC680; DO NOT use for
battery cycling
* Set charger on lead acid (flooded) setting
* Only use models with DeltaVolt charge profile; multi-bank
charger outputs may be paralleled for higher amperage when
charging PC1200 or larger batteries
* Set charger switch to position #5
* ONLY for light cycling applications (<40% DOD) PC310 to
PC2150; set mode: 3-stage, battery type: Gel, and battery
temp: warm
Bottom line is the 3-4 newer gen hi tech batteries being mfg'd today do require care when choosing charger/tender to ensure you dont damage the battery as perf the batt mfg's themselves which is what i was refeering too and tried to pass onto all of you here that these hi tech batteries do in fact have specific charging requirements which i copied & pasted from the batt mfg's for you to see that i didnt come up with it out of nowhere.
You can belive the battery mfg's say or not,it's up to you.
Have a good holiday season & New Year.
