Topic: batteryminder chargers??

[AT853rxwh]

thats whats weird, i ran it COMPLETELY down testing the jb3, and its been charging about 30 hrs or more now, i just busted out the multimeter just now, and i noticed that the 12v sla is only at 5.5-6volts charge, before the tests, i believe it wasa at about 12.6volts or something, so maybe its the charger??

Can't measure the voltage offa batteryminder, without load it doesn't put out at all... What is the batt voltage?

[recordista]

also, when i take the charger off of the ac wallwart thing i have, the 'battery condition' light is still on while the battery is still connected!! kinda weird, does that mean its 'desulphating'

The light is on because the battery voltage is above the light's setpoint.

Desulphation only occurs when the battery voltage is above another (higher) setpoint (~13V IIRC) so it will only happen while the unit is plugged in.  I have standalone desulphators for big batteries which I leave connected all the time (once they're adjusted properly.)

batt voltage is a 12v sla ecocharge, it is only pulling 5.5-6 volts when i measured!!

recordidta, so youre saying that desulphation ISNT going on?? just charging?? should i leave it in longer, and just hope it reaches "float"??

float starts when the battery condition light starts blinking, correct??

Hmmm, even a deeply discharged 12v sla should show at least 10v  wonder if you killed it?

heres what i did, when i got the battery minder charger, it had the wire w/ a blue hole and a red hole, to easily put onto a bqattery, so i snipped the red wire, put that to the "hot" wire, snipped the blue wire, put the "cold" to that one!!!
now wtf, bothe seem to be dead?

did i reverse polarity??? i thought the batteryminder ws ready for shit like that??

any help is appreciated!! especially since im leaving for phish shortly!!

[F.O.Bean]

and i just checked the battery again, steady a +5.50 volts and -5.50 volts, WTF??

[F.O.Bean]

alright, just found this lil piece of info, WTF is this junk, screw batteryminder, my "resting" voltage is 5.5 volts, so the charger is basically useless

VERY misleading company.......

so my next question is, how did my 12v sla get down to 5.5 volts??

i am clueless about this crap

Umm if you managed to get an 12v sla down to 5.5v you did something bad to it, and it wasn't with the charger...  You might be able to get it to pulse enough to get the voltage up but that might be doubtful.  If you can get someone to bulk charge it to get to 10v you might be able to salvage the battery, but again deep discharging an sla down to 5.5v is a very ungood thing... 

As to batteryminder being misleading, eh, dunno about that, they do say it is microprocessor controlled and that no voltage is apparent unless there is a good batt attached.  That is the whole idea behind the battery testing (when you hook up the battery to the charger unplugged it tests the battery)

As to charging for 30 hrs, they even say in the owners manual allow up to 72hrs...

http://www.vdcelectronics.com/images/12vInstr-4%2016%2002.pdf

The recommended max level of discharge for a sla battery is 85% or 10.2v  Anything more than that can cause PERMANENT damage to the battery.

first off, plus t for your patience and everything else bro!!

i have been looking for that batteryminder manual EVERYWHERE!!

that expoalins alot, hmmm, im wondering how the hell i got my 12v sla down to 5.5 v resting voltage??? no clue there, just did my jb3 testing and BAM, seems dead!!

so im gonna follow those instructions and see what happens!!!

leave it on for 3 days, if nothing, let sit for at least 8 hrs, then try desulphating for a couple weeks, then try again!!!

just trying to figure out how the hell i killed that battery???

ive run down my eco's MANY times before, granted they were 6 v, but still, and they have ALWAYS come back to life so far!!

What you can do, and I had to do this with one of the batts that came with my mp-2 is charge it up enough for the batteryminder to be able to try to recover it. 

You have a couple of options

1.  charge it with a bulk charger to get it up to a high enough voltage for the batteryminder to work
2.  Start it charging parallel with a good 12v battery and once it comes up enough just leave the one that was at 5.5v on by itself...

thanks bro, whats a bulk charger tho???

tried desulphating the battery for about a week, voltage is still at about 4.43 volts

so put a bulk charger on it, then use the batteryminder???

do you think an xenotronix charger will werk???

[AT853rxwh]

Bulk = regular charger no smarts...

I had one do exactly the same, the light came on (dimly tho) and told me it was charging... (simple check with the volt meter said otherwise) 

Any charger that won't look for voltage first should be able to get it to a higher voltage so you can use the batteryminder...

[F.O.Bean]

so gte a charger that isnt "smart"??

i guess i could do that at wlamart huh?

[AT853rxwh]

Or borrow one...  Do you have more than one 12v battery?

just one 12v 7.2 amp

would an xenotronix werk ya think??

even tho its smart, thats the unbranded eco-charge, and it may werk w/ my eco gp-90!!

the one thats dead!!
