You mention 10 hour rate ,my lowest output charger is 700 mA (not 120 ma ) Would it be safe do you reckon to connect it for say 10 minutes just to see what happens ? However, on checking the manufacturer's sites to refresh my knowledge, I believe I may have been more or less correct. This is the price (excluding shipping and handling fees) this seller has provided at which the seller has sold the same item, or one that is virtually identical to it, in the recent past. International Shipping - items may be subject to customs processing depending on the item's declared value. Your country's customs office can offer more details, or visit eBay's page on international trade. Estimated delivery dates - opens in a new window or tab include seller's handling time, origin ZIP Code, destination ZIP Code and time of acceptance and will depend on shipping service selected and receipt of cleared payment - opens in a new window or tab. This item will be shipped through the Global Shipping Program and includes international tracking. Will usually ship within 1 business day of receiving cleared payment - opens in a new window or tab.

When the battery discharges, some of the lead from the plates combines with the electrolyte to make lead sulfate (PbSO4) which builds up on the surface of the plates as crystals (as electrons leave the battery as electricity).
If it is clobbered you probably won’t be able to charge it anyway, the internal resistance will be much to high. The "off" amount and percentage simply signifies the calculated difference between the seller-provided original price for the item and the seller's current discounted price.

However, users should be awarethat when charging from fully discharged, the battery can draw an initialcharge current of approximately 2cA. If it will accept a charge then you can can charge it up at up to an amp, depending on the charger, if a constant voltage type, the rate will start to tail off as the voltage comes up. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. When the battery is next charged this process is reversed with the lead sulfate crystals breaking down - returning the lead to the plates and restoring the electrolyte to its original composition. Care should therefore be taken toensure that this initial charge current (if ungoverned) is within theoutput capability of the equipment. For a 12V battery, the output voltage of the charger is set to 13.8V, and the charger tries to maintain this under all circumstances.
This is a particular problem when batteries are left discharged for long periods of time and when they are deeply discharged.Lead sulfate on the plates of a battery acts like an insulator reducing the plate area in contact with electrolyte.
If the battery voltage is lower than this, then it will charge until it reachers 13.8V, and then stop. Over time this build up of lead sulfate crystals will result in a battery which cannot hold much charge - i.e. If it does start to charge and the voltage comes up very quickly then that also indicates that it’s most likely kaput.
If we raise the voltage higher, the battery becomes fully charged, but if left on at these higher voltages for long periods it can become damaged. It can also be used every few months to keep batteries in the best possible condition all the time.
Maintaining the voltage under all circumstances implies the the current would be unrestricted but this would not be practicable in a small charger so the current is limited.
Desulfation will not bring batteries with a shorted cell or worn out plates back to their former glory, but it is a valuable tool for anyone depending on battery storage for power who cannot afford to buy new batteries.When lead sulphate crystals build up on the lead plates, it is not an easy task to remove them and thereby recondition the battery.
Breaking down hardened crystal build up and dissolving cystals back into the electrolyte requires a charging voltage much higher than would ever be used to actually charge the battery.

They were expensive, even back then, but they did last a long time, even despite the abuse, such as on the odd emergency occasion being charged in parallel from my van battery. This may be just a couple of amps in a small battery charger to many amps in a large power plant. But, if you were to put this constant high voltage through the battery it would overheat, release gas, and could potentially explode.
As the battery becomes charged up and the voltage rises, the supply current becomes less, until at some point the current supplied is below the current limit. Therefore pulse conditioning is used to give very short blasts of high voltage sufficient to shift the lead sulphate crystals without overly raising the temperature of the battery as a whole.Every lead acid battery has a resonant frequency at around 2 to 6 megahertz. If pulses of electricity (high frequency, high voltage, but low power) are sent into the battery, rhythmic beating (resonance) of the plates causes the crystalline deposits to break up and the sulphate returns to the electrolyte solution.This process takes three to four weeks typically during which time the battery must be trickle charged (in parallel with the desulphator) so that the battery ends up reconditioned and fully charged. Below is a video showing the lead plates inside two identical batteries - one which has been desulphating for three weeks, and one which has been left in its original sulfated condition.Note that the voltage measured across the battery terminals will drop as the desulphation takes place as the internal resistance of the cells is reduced by the clearing of the crystals on the lead plates. At the same time, the amount of charge that the battery can hold will be increasing.Build a Battery DesulfatorA DIY battery desulfator circuit originally published in the US-based Home Power magazine has been successfully made for many years all over the world. Here are links to the instructions to build the Low Power (circuit design above, and finished example circuit pictured below) and the High Power versions of the circuit. These links are to be found together with a lot of other useful information here.For more infomation about battery desulfation, click here to visit the very useful Lead Acid Battery Desulfation Newsgroup. Also try this link to Mikey Sklar's Mini-D 12V battery desulfator, and his second generation battery desulfator with the addition of a display and data logging. If your multimeter can read amps put it in the line sometime and I suspect you will find that it will hardly ever read 700mA so that would be ok for charging.
