BatteryMINDer on Wind Power

I plan to install a BatteryMINDer Model 12248 for continuous charging/conditioning/desulfation of my house bank of three Lifeline 210 ah AGM batteries. I wonder if anyone on this forum has experience with this charger/conditioner? All reviews that I've found elsewhere are very positive. BatteryMINDer® 12-Volt 2, 4, or 8 Amp Charger-Maintainer-Desulfator-Conditioner w/ABS-248 | All | Battery Chargers by

My plan is to disconnect my existing wind turbine (Air-X Marine) from my house bank and connect it to a new 210 ah AGM battery, and from that battery wire an inverter. The BatteryMINDer would plug into the inverter and be connected to the house bank for continuous charging/conditioning/desulfation from wind power (solar to be added later). My other charging circuits - alternators and shore power automatic charger - would remain as they are. I'd have the option of plugging the BatteryMINDer into shore power for long-term maintenance during storage. The new battery would extend my house bank energy capacity while remaining separate. As I refine my plan, any constructive comments on this scheme would be welcome.

Re: BatteryMINDer on Wind Power

Hi! JAMU, I have looked at the system your ether, are going to..or are using now. I have been myself wondering why this is not evolved more then us.. meaning You and I..LOL I understand the charging unit concept however, What are we really missing here? I hope someone with battery sense will add some value here. I read a paper that was done and find it quite interesting. will copy it on here..

** Batteries are like a box of chocolates.. you never know what you get!

Re: BatteryMINDer on Wind Power


- EDTA (ethylene diamine tetra acetic acid) is well known to the medical
profession as a chelator that tie up poisonous heavy metal ions to form
a chelate or complex ion that can be eliminated from the body. This
same reaction will occur in a
battery to drive lead sulfate to
dissolution. This reaction does not destroy the EDTA, rather the EDTA
is regenerated and the sulfate is precipitated to the bottom of the
- Proponents of EDTA therapy recommend that EDTA be added to new
batteries as a preventive medicine. 4 years ago friend bought 5 new
batteries. 4 batteries treated, one did not. The untreated
died last year, all 4 treated batteries load test like new.
- EDTA is a dry white powder available as DI-SODIUM SALTS or
TETRA-SODIUM SALTS. It's the TETRA-SODIUM you want for your
battery. Friend
paid US$ 4/kilo in Penang - 80 Chulia Street - Owner 81.
- Be aware that EDTA will not dissolve in
battery acid but dissolves
easily in distilled water so.. “DON’T” try dumping the powder directly into
- How much? Best information so far is one tablespoon EDTA/liter of
cell capacity. This doesn't seem all that precise so try 1
tablespoon per cell on a 70AH
battery. For larger batteries scale up.
Use a proper kitchen measuring spoon, not the eating kind, EDTA
dissolves easily in an equal amount of distilled water. Mix, dissolving
the lumps, then add the EDTA solution to your
battery one cell at a time.

Be aware this therapy will not restore life to shorted, disintegrated,
or warped plates but will restore badly sulfated batteries that have
been left unused awaiting disposal.

- In most cases a one time treatment is all that’s required for
batteries in service. Deep cycle batteries from the scrap yard if badly
sulfated may require a double treatment and a month connected to your
bank for results.
- Friend visited the
battery graveyard at a Marina and found several test
specimens. Example: a
battery that measured 11.8V no load and
absolutely zero under load test will now start a diesel after 3 weeks
connected to his bank. At time of this writing these junk batteries have
been in service about 4 years and show no sign of degradation.
- Treatment as preventive medicine to new batteries gets no reaction.

But be careful; pour slowly into an old, heavily sulfated
battery. It
will boil, spit, sputter, and quickly get hot just sitting there before
- Over the long term the chelate will collect in the bottom until it
starts to cover plates and reduce available area. friend assured that the
chelate is an insulator so all that will happen is reduction of plate
area reducing
battery performance. The BIG question: can this chelate
be flushed and
battery life can start over as a virgin?
- Apart from my friend's experience - I have 1
battery that is still operating
my radio after 8 years continuous service - secret = Charge no more than a
digitally calibrated float charge of 13.52 volts - plus a shot of EDTA 5 years ago.

I tried to find it again and failed to find it.. So who ever wrote this Many Thanks!!

Lead acid batteries require that precipitated sulfate to function. It needs to be dissolved and reacted into the electrolyte as sulfuric acid. That is what charging does. Especially the well-proven trickle and equalization charging regimens.

Seriously, the magic way to restore a lead acid battery is to buy a new one. Nothing quite like new batteries.
