Making a bad 12 volt battery good again

[Santa]

Watch the vid. It's dang impressive, and I don't think it's bs. I can't tell how many of these deep cycle batteries I've used up and gotten rid of over the years, thinking they were dead. Baking soda water and then alum water flush, then fill with alum water and charge er up. Too cool. :)

There are electronic devices on the market that you hook up to your battery that pulses a frequency back into the battery that shatters the sulfer crystals (they resonate at the sulfer crystal frequency thus shattering the crystals) from building up on the lead plates (bulging the battery sides) thus prolonging the batteries life by not allowing the crystals to damage the lead plates (cell). By shattering the crystals back into liquid form the acid never looses its strength
They work great...I have a few of them installed.

Solar charge controllers have an equalization charge where it blasts extra voltage through the batteries to rid them of sulfation...

That is pretty cool.

Have any links of these devices you are talking about? My car battery died a few years back after my alternator boiled the juice out of 3 cells. Then I let it sit 3 or 4 months and it went total dead zone. I dumped the juice and rinsed it with boiling water a few times, a ton of burnt black lead came out. Then added fresh acid but it wouldn't take a charge till I hit it with 16 volts at 25 amps, that made it click and take a charge. I still am using this battery but need to charge it once a month or it gets real low.

I read about the OP video and it seems to work but in a different way then sulfuric acid and water, tends to permanently kill the battery after a few months from what I read. I'm sure some batteries will handle it better than others but buying fresh acid for 8 bux was a better choice in my view.

I have something real similar as this gadget.

I Velcro'd this device along side the battery.
I have never been able to get a full 5 years out of a battery until I started using one of these....its going on 7 years now....hoping to double the battery life with the same acid. Maybe once it dies, depending on lead plate condition, I can refill the battery with new acid and get another 5-10 years....but who knows!
I will be incorporating these in my solar lead acid battery back up system for the house.

I've used this stuff http://www.chinadepot.com/batripod.html on cheap $15 batteries from the junk yard that metered 12v but couldn't start a car to rejuvenate the battery to new....then replaced the battery acid. Problem with this is you don't always get batteries with good cells. Be sure to get batteries that don't show the side walls bulging to ensure decent undamaged lead plates.
Watch the video's............they are very helpful for beginners.

Need to figure this out before I buy one, not sure what this one does... Looks like a good technology just need to get my head around it.

Basically all it does is take a charge from the battery that charges a capacitor (time constant circuitry set at the resonating frequency of sulfur crystals). Once the capacitor charged it then discharges back into the battery at that resonating frequency that shatters (dissolves) the sulfur crystals and keeps any formation of crystals from forming. Thus it keeps the acid at its strongest and the battery having any cell damage which is the biggest problem with lead/acid battery's.

A basic simple concept that works.
Any questions just watch the video's on china-depot website about sulfur crystals forming in lead acid batteries.

What is ALUM dujiqui and where do I buy it?

It's basically aluminum sulphate, and it's usually in the baking or spice section of the grocery store. It's an ingredient in baking powder and is also used in canning pickles to help keep them crisp.
My Mom used to tell me to dab a little on my canker sore when I got one. Tasted awful. I have no idea why it works in a battery. Maybe it fills in the pits on the lead plates that the oxidation caused?

Those electronic devices you folks are mentioning are for preventative maintenance. They make a battery last longer but don't bring a dead battery back to life as far as I know. They've been using them in solar inverters for years.

Most dead batteries are caused by sulfation of the plates... that's why it's important to this thread.

I use a Battery Minder to maintain and desulfate batteries.

Here's one version:

They have other versions too, some that can handle multiple batteries at a time, others that are designed to mount under your hood so you can just plug your car in at night.

Here's a trick I use to get my 18v batteries to charge after they're dead.

Bought one of these two months ago for 19.95, they have gone up 5 bucks.

You can browse around here and find all kinds of schematics for desulfators.

21 paper bucks ..The Schumacher SEM-1562A 1.5 Amp Speed Charge Maintainer is a unique AC powered automatic charging accessory for use with everything from smaller batteries designed for motorcycles, tractors and mowers, to standard car / truck batteries and marine / deep cycle batteries. Designed around an internal microprocessor which constantly collects information from the battery that the unit is attached to, the SEM-1562A effortlessly and quickly ensures that your 6 and 12-volt batteries are maintained at optimal levels, and does so in the fastest and most convenient means possible.

Microprocessor Controlled Charging for 6 and 12 Volt Batteries

Microprocessor controlled charging and maintenance is simply the easiest way to keep batteries at optimal power levels. This convenience and speed is experienced from the moment that the SEM-1562A is connected. First, the unit utilizes the user's choice of either easy-to-connect and remove battery clips, or permanent ring terminals (both included), each of which allows for charging or maintaining of batteries whether they be in or out of vehicles. The SEM-1562A also features automatic voltage detection which allows it to automatically determine whether the connected cell is a 6-volt battery or a 12-volt variety. This eliminates the possibility of damaging a battery due to choosing the wrong charging settings. Once your battery type has been identifified, a multi-phase charging process kicks in which plays out via the unit's automatic Charge / Maintain modes. Tipped off by the data analyzed by the onboard microprocessor, your battery is supplied with a constant charge until it reaches a preset level - at which point charging ceases. Eventually, if the charge falls below a certain level the SEM-1562A automatically transitions into Maintain Mode, delivering a small, safe charge that will raise the battery's level back to where it should be.

In addition, because of the constant monitoring the battery, the SEM-1562A can react to charging needs swiftly, efficiently and accurately, allowing charging cycles to click on and off in the same way. Because of this, batteries can be left attached to the SEM-1562A indefinately for storage without the risk of overcharging and/or damage. Additional features include: automatic temperature compensation which adjusts the maximum charge voltage and maximum maintain voltage based on the ambient air temperature; thermal runaway, which automatically reduces the current if it detects the battery may be getting too hot; an auto-start feature that keeps power from flowing unless a proper connection exists, or in the case of a reverse hook-up; and a Desulphation mode for charging batteries left discharged for an extended period of time.
