Re: [EVDL] BATCURE -- ? real or not

Here's the instructions for the "BatCure Product":

Follow the simple procedure as below to eliminate
SULFATION from your mechanically sound batteries. =


Before you carry out BATCURE treatment on batteries
that have lost power storage capacity, it is important
to know the present health condition of the battery
that is being subjected to BATCURE treatment.


Note the battery volts first. For automotive 12V
batteries the minimum volts should be above 10.5Volts
and for 6V battery it should be above 5.25Volts.These
parameters for automotive batteries are valid for a
battery that has been removed from service within in
30 days. If the batteries are removed from service for
more then 30 days then the volts may be on lower side,
such batteries be charged for 2 to 3 hours and then
disconnected from charging machine. Allowed to settle
down for 12 hours and then remeasure the volts. If the
volts are above the minimum requirement as mentioned
above, the battery is selected for further


Note the specific gravity in each cell with
hydrometer. You will find different gravity in
different cells. However, heavily sulfated cells will
show exceptionally low gravity as compared to other
cells. Mark the very low gravity cells.


It is the most difficult job to find a mechanical
damage to a particular cell or cells. However, on the
basis of our experience we have tried to enlist some
important steps that can help us to find a mechanical
damage of the cell.

After you have noted the battery volts and specific
gravity in each cell, connect the battery to a
charging machine. Apply 5 to 7 amps for batteries up
to 70 ah capacity, 8 to 10 amps for 75 to 130 ah
capacity, and 10 to 15 amps for 135 to 220 ah capacity
battery. Carry out battery charging for 3 hour. After
3 hour observe the following while battery is still
being charged.

Is there a uniform reaction in each cell? =

Is there any one or more cells giving high bubbles as
compared to other cells? =

Is there an exceptional rise in battery electrolyte
temperature? =

Is the current passing in each cell? =

If all the cells are giving uniform reaction and
normal gassing is observed then the battery has a
better chance of fixing with BATCURE.

If one or more cells are giving exceptionally high
bubbles or gassing then it is possible that such cells
have heavy shedding of active materials, separator
puncture, mechanical short, or sludge formation at the
bottom area. Such cells will not give any improvement
in the gravity and will remain same as it was before
battery was put to charge. Such batteries are

Most batteries that have been sulfated will give a
rise in electrolyte temperature but will not have
uneven gassing in all the cells. Such batteries can be
preferred for BATCURE treatment.

If you find that one or more cells do not give any
bubbling at all then it confirms that the current is
not passing through that cell or cells. This may be
due to inter cell-welding damage. Such batteries are
also discarded.

After you have made above analysis, remove the battery
from the charging machine. Let it come to room
temperature and then remeasure the battery volts and
gravity in each cell. Compare the volts and gravity
reading with that taken before the battery was put to
charging machine for 3 hours.

If you find that there is an improvement in battery
volts and gravity in each cell, such batteries is
selected for BATCURE treatment.


Add 5 ml BATCURE in each cell for batteries having 32
ah to 70 ah capacity, 7 ml per cell from 75 ah to 130
ah capacity, and 10 ml for 140 to 220 capacity
batteries. Mix it well with electrolyte using
hydrometer. Reddish yellow color will be there in
electrolyte. Leave the battery in idle condition till
the electrolyte becomes colorless. The less sulfated
healthy cells will have faster discoloration and more
sulfated cells will have slower discoloration. If the
cells are mechanically damaged then there will not be


In the case of VRLA batteries, you will find a plastic
strip on the top of the battery case. First remove
this strip with the help of a screw driver or a Sharpe
cutter. Once you remove the strip, you will find that
there are 3 or 6 (3 for 6Volts and 6 for 12Volts)
small vents which are covered with a rubber cap.
Remove the rubber caps from all vents. Then add
required quantity of BATCURE in each cell. (Quantity
of BATCURE required depends on the size of the
battery, please contact us).After addition of BATCURE
add distilled water unto plate height in each vents.
After water has been added, shake the battery to and
fro for few times for uniform mixing and then leave
the battery for 12 hours.

After 12 hours carry out 3 to 5 charge -discharge
cycles to remove the sulfation completely.

Once the battery has come to required level of
capacity, close the vents with rubber caps and reseal
the top with the strip using suitable adhesive.


After the discoloration of electrolyte has been
completed, Cary out battery charging using different
amps for different ah capacity batteries as used
earlier for battery test analysis. Continue to charge
the battery till full gravity is observed in each
cells and the battery volts reached above 15.5V for a
12V battery and 7.5V for a 6Volts battery.

Fully charged battery is then removed and allowed to
settle to room temperature. When the battery has
cooled to room temperature, note the volts and gravity
in each cell. You find that the battery is showing
more then 12Volts and 6Volts for respective nominal
volts of battery. All the cells will show at least
1.200 specific gravity in each cell.


A charged battery is required to be discharged for
sulfation removal. Discharge can be carried out using
standard discharge testers or dc halogen bulbs.
Complete discharge is recommended.

Recharge the battery/discharge the recharged battery
for at least 3 to 5 times for complete removal of


After the battery has been cycled for
charge/discharge, carry out a load test as per
standard load testing procedure.

We strongly recommend that all new batteries or
in-service batteries be treated with BATCURE to
inhibit sulfation for longer sulfation free battery
life. Add only half the quantity of BATCURE that was
used for sulfated batteries. For new or in-service
batteries no cycling is required. Add BATCURE once in
2 years to keep your batteries healthy.

Doesn't sound much different than the bottle of
battery additive, Harbor Fright sells, for reviving
batteries.... I'd be interested in the ElectroGel
product, make my floodies into AGM's, kinda..... lol

Frankly, their proceedure automatically results in an increase in amphour capacity even WITHOUT adding their miracle cure. Basically, they sort out batteries with bad cells, add water if needed, then give it a full equalizing charge (over 2.5v/cell), then a discharge cycle (to 1.75v/cell). Repeat this for a few cycles, and the battery magically improves!

Re: [EVDL] BATCURE -- ? real or not

The "cure" for sulfation is given in the description. You reverse sulfation
by charging the battery.

This reminds me of something mildly amusing.

There's a battery dealer several miles from my house. I buy batteries for
our ICE cars from them because they carry East Penn brand, which I like.
But that's not their big money maker. They're in a kind of low-income
neighborhood with a thriving population of aging Detroit Land Yachts. Their
big turnover is in "refurbished" batteries, which they sell for $20-30 each.

I asked one of their techs once, "So, just how do you refurbish a battery?"

"We charge it," he replied.
