Cardiff Giant: wouldn't have been better to dump all the water and acid from the battery,
and then refill it with fresh distilled water and epsom salt mix?
CR2504life: milli-Ohms, not Ohms !
Phillll: For the record, the meter is not telling you 759 OHMS 'across the
terminals' but that the INTERNAL, series resistance of the battery is 759
MILLI OHMS = 0.759 OHM
Draugr Hessler: I believe you can get battery electrolyte (acid) at any battery dealer.
They sell it in cardboard boxes with a heavy plastic bladder inside. I have
three gallons in the barn that have been there for about 5 years and
haven't leaked a drop. I know glass will contain it but so will a battery,
and the battery case is plastic. So I believe some plastics will safely
contain it and do not have to be glass.
Draugr Hessler: Someone who thinks and doesn't automatically go out, flip out a piece of
plastic and buy a new one. I like that. That is American ingenuity and
spirit that, unfortunately, most of our countrymen have lost. There was a
time when, if the axe handle broke you made a new one. Now the axe and the
handle are thrown away and is replaced either by a chainsaw on a credit
card or some poor Mexican that gets paid slave labor rates.
Draugr Hessler: I am using VERY expensive 6 volt (wired together to get 12 volt) batteries
for my backup solar system. The whole thing crapped out on me a few weeks
ago after running fine for over a year. All the fluids are above the plates
(Thank God) but I am having a problem getting them to take a full charge.
From what I remember they never really performed as well as I thought they
should. There are eight of these big Interstate batteries (about twice the
size of a normal 12 volt car battery each). When connected to the Aimes 5k
Pure Sinewave inverter they never really held up as long as I expected.
Just running the lights at the house and an occasional TV I am lucky to get
10 hours of use before the low power warning beeper starts going off. Is
this normal and I just need more batteries or is something wrong. I have
separated the batteries and charged them independently. When checked
individually for six volts they register just barely in the green, but
under a load fall immediately to the weak side of the (Harbour Freight)
load tester. When connected 2 at a time for 12 volt they peg the 12 volt
needle nearly to the red, but under a load for ten seconds they drop to
about the halfway point between good and weak. Are they performing as they
should and I'm just expecting too much or is there a problem?
Neil Caulfield: Will the acid on the top of the battery cause burns to your skin? I know
once it dissolved my clothing and the upholstry on my car floor but if i
get a little bit on my skin would i be fine, I have a similar interstate
Draugr Hessler: I believe it is always better to use electrolyte (battery acid) as a
replacement fluid for a battery as opposed to distilled water. Distilled
water is fine for say topping off a low cell, but replacement should be, in
my opinion, battery electrolyte.
Draugr Hessler: Use a coffee filter. Of course it (the acid) will eventually eat the paper
but not immediately. You will have time to strain out any trash. But to be
honest, I would just purchase a new container of electrolyte (battery acid)
from any battery dealer (granted that you can budget it. There is nothing
wrong with reusing things to save money. Lord knows that I have had to many
times). I have three gallons in the barn. It comes in a cardboard box of
all things. Of course inside the cardboard box is a thick plastic bladder
that actually contains the acid. from the bladder is a small rubber hose
with an old fashioned pinch valve to control or stop the acid flow from the
battery. Wear old clothes, rubber gloves if you have them and of course
safety goggles. Battery acid in the eyes hurts a lot. I know from
kay ger: An off topic observation for those lured by creative marketing terminology.
The battery is labeled as a deep cycle battery; for this battery this
means it can be depleted of charge and recharged... nothing new for a lead
acid battery. The technical term deep-cycle applies to ni-cad batteries,
which requires depleting the charge entirely using a deep-cycle charging
system for recharging; to prevent a memory charge....it is not a plus!
Draugr Hessler: I am wondering if anyone has ever employed a device that when attached to
the battery, or the battery set into the device, creates a strong but very
fine vibration throughout the battery while the epson salt solution is
used. It seems to me that the vibration of the lead plates within the
battery may accelerate the desulfation of those plates. Another idea I had
was to add a very fine abrasive to the epsom salt mixture, like
diatomaceous earth. Now imagine a battery set into a cradle that acts as a
spindle allowing the battery to be tilted at any angle. On the bottom of
this cradle is some form of device that puts out very high frequency
vibrations but not so intense that it damages the battery. Take for example
an old, variable speed, electric sander attached to the bottom of the
battery cradle. Then employ the use of a very slow turning motor that
literally spins (very slowly) the entire battery so that the fine abrasive
material is evenly distributed. This seems sound in theore. Quite literally
the internal lead plates, after a few hours, would be scoured clean right
to bare metal again. The process could be repeated several times with a
rinsing solution to discard any abrasive material as well as the sulfate
buildup. Has anyone ever heard of this or any ideas of why it would or
wouldn't work? KPE DRAUGR 4-27-2014
Pam Whittington: Don't forget to clean those posts!!
Triangles: Oh no! It's Megatron! Quick someone call Optimus Prime.
Andrew Jamison: I am sorry did not mean to doubt your skills just had to poke fun at the
Model name of that battery
Frank Lowe: A battery works on a chemical process it can not be reversed.You can add
more chemicals to make it last a little bit longer but come next fall it
Will get you.
KmanAuto: No, do not remove the acid. You add to the acid.
KmanAuto: That would depend on how bad the battery is when you add the epsom salt. If
the battery is already having problems, it is a band aid. If your battery
is aged, yet, still doing fine (say, 3-5 years old, still starting your car
fine, or running your trolling motor ok etc...), then it can greatly
increase the battery life.
niz76: From what I understand, the epsom salts merely increase the conductivity of
the electrolyte. So is this really desulfation? Do the desulfators at
Motty Ruttner: did you maintain it when not in use
Big Andre': Can I desulphate with Epsom salt, then add new battery acid ?
Andrew Jamison: with a battery called Mega Tron did you expect it to work?
Christopher711: I kept the water level above the cells.
Jyme Bale: Sulfuric acid stays acid, it does not go bad, it is a very strong corosive
acid, you could dump the acid out get new cells and filter the acid into
the cells, don't know how you'd filter it since only glass will contain it,
there must be a way.
Keegan L. Patterson: Just a friendly usability suggestion: Either label your videos "1 of 4", "2
of 4", etc. or, better yet, combine into one single video. You have way too
many videos to easily find which is which, nor to determine which is the
first in this "series".
KmanAuto: You only add new acid to make up SPILLED or REMOVED acid. If the battery is
low, you use Distilled Water to make up acid that is lost over time.
Motty Ruttner: when not using it over the winter you should keep the battery on a battery
KmanAuto: Yes, I know. Unfortunately, cant go back and change the video :)
MrAgnostic: is it a band aid or a long lasting fix?
Joselito Pancho: OMG, for real?
Keegan L. Patterson: I think they only sell that for batteries that ship "dry" (i.e. motorcycle
strake750: A Megatron! This is a job for Dr Who
Nick Duvall: That is one of the best batteries available, to be honest.
KmanAuto: And even some that have dead cells :)
pranav singh: do u need to remove the acid of the battery before pouring in epsom salt
solution? please reply at pranav71295@gmail .com :)
Daniel Moeller: As long as it didn't turn into a somewhat humanoid robot and try to kill
him, he should be okay.
KmanAuto: Sir,. this is called experimentation. Utilities are now experimenting with
this as well to reduce loads on their generation plants. The exact same
concept on a MASSIVE scale. You do not do something on a massive scale
without first trying it on a smaller scale. I have done the smaller scale.
KmanAuto: I have brought back into service around 30 batteries using this method. As
long as their are no completely dead cells, it should work.
Christopher711: I bought a battery 11 months ago and am charging it for the first time
today. I think that might have been a mistake. Hope it will hold a charge.
KmanAuto: Or Optimus Prime. But I think Dr. Who would do a better job. Though, I am
the Battery Doctor, so.....
KmanAuto: I know :)
KmanAuto: Rock the battery gently if possible to allow the solution to spread. Then a
low amp charge or float charger. 2 amp or less. Next day, if the battery
still is not taking a charge, do a regular charge.
AquaticBoardwalkEngineer: Interstate batteries..... Super good batteries.
Bonnie Flory: I am a maintenance man. One of our employees broke a brand new 3 day old
battery. I fixed the crack first. Luckily I did not return the old bad
battery yet. So, dumped the acid from the old battery into a plastic bowl.
I used a plastic funnel and put a coffee filter in it to strain the old
nasty acid. I strained it twice. Then I added the old strained acid to the
broken new battery. It has been 3 month so far and so far there is no
problem at all.
Big Andre': The reason why I am asking is because the Auto Zone sells sulfuric acid to
put into batteries, but you have to dump out the old acid. So I was
thinking, desulphate w/ epsom salt first, then dump the old acid then add
the brand new battery acid.
Jim Viau: KmanAuto, If Im not mistaking, your meter shows milli Ohms not Ohms. Just
thought Id mention it. It makes a huge difference when you do the math.
