Can it desulfate? Can it charge deep-cycle batteries heavily discharged to 10V?

Manual states that "If the battery to be charged has fallen below 2 volts, the battery cannot be recharged..." It has a reconditioning function, but it's up to you to decide if your battery actually has a level of sulfation and the 24-hour cycle of electrical pulses will be of any help (manual states "More than 24 hours may be needed to restore performance on some batteries. If so, repeat the process").

I am not an auto-mechanic. I purchased this charger to charge a 12V Marine-grade battery. The battery was completely "dead" but was only a year old. There is a deep cycle-recondition selection. I chose that and it took a full 3 hrs to go through the cycle. It charged the battery, which is now going on 5 years old and STILL re-charging on only the standard charge. I hope that helps answer your question.

I have used it for about 6 months and found that the recondition selection seems to do a good job. I have also recharged some very weak batteries with good luck.

Yes - to a point. The best option is to keep your batteries from becoming heavily sulfated in the first place. This charger, if used perhaps for a monthly top off in a vehicular application, should prevent that.

I have charged batteries as flat as 2.5 volts! Yes it has a maintenance mode for desulfation.

The best way to fully charge a deep cycle, especially if not used for auto is to use a 3 stage smart charger....this is the ONLY way to fully charge a deep cycle battery.

It specifically says in the instructions that it is not recommended for that. I did not know that before I bought it. I bought it specifically to use it with an Exide deep cycle battery. http://www.amazon.com/gp/product/B003FFTFBW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 The charger maintains the battery's charge just fine, but I simply use it to keep the battery topped off for emergency situations. If I had it to do over again, I would probably get a more robust charger that puts out more amperage, say 5-10 amps.

Absolutely! It works with any 12 volt battery. I use it for two different batteries for something like powerwheels. Note that for desulphating a bad battery, you may need to leave it connected for a week or more. Read the charger's instructions.

I am using a 10w on my deep cycle battery on my boat. It keeps it fully charged after a few day of sitting in the driveway.

Yes you can. As stated in my other responses, I used mine for all situations, from cell charger to running power strips to power my house. A separate battery charger is ideal, bc then the charger is mobile, not stuck with the vehicle. I would recommend the Die Hard Branded one from a local auto parts store, roughly $50, it will do AGM(deep cycle batteries), trickle charge and conventional batteries.

I would have to look it up in the manual. Some deep cycle batteries like AGM's require a higher than standard voltage for charging. Perhaps you can download the Owners Manual pdf online.

I am charging 4 deep cycle marine batteries with no problems using this charge controller. So with your use it should work fine.

Wasn't aware of this [requiring a non-std batt] - mine works fine with a 12 volt deep cycle from wally-world. There are other issues with this model (brand?); connections and side-scanning limitations.

Probably- it puts out gobs of power. However, different battery types have different charging profiles- the current supplied needs to change as the battery voltage rises; just ramming electrons in until the battery voltage is where it should be will probably damage the battery. If you use a charger DESIGNED FOR YOUR TYPE OF BATTERY you should be OK. The power supply can supply the juice, but the charger has to control the process and protect the batteries.Even cars have Voltage Regulators to control the charge rate to the battery.Hope this helps.Bill K3DC Probably- it puts out gobs of power.

I also noted that deep cycle was left off these units , I have found that using the standard position on deep cycle will go to desulfate mode on deep cycle when determined by the computer. since the computer is evaluating the connected battery as it is charged I just assumed the company decided it was not necessary to have another position. if this is the case they should have included a note with these units.

I would not use this charger on a AGM or gel batteries. It has a voltage ramp-up (15-16 volts) periodically to reduce accumulation of sulfites on plates which is not good for these types of batteries.

I probably wouldn't if it were mine. Some electronics and batteries may be damaged by a power source that provides too much current (Your charger needs .3 amps and this supply puts out 1 amp). The device I am using with my power supply is a cheapy unit that is inexpensive, so no harm if it gets fried. I am also using my power supply to take the place of batteries, not for charging batteries like you're wanting to do. My recommendation is to pass on this as it might cause damage. Good luck :-)

Yes regardless of size. Some autos have two batteries (diesel powered cars come to mind). And while this charger is a mid-sized charger, it does have a desulfating feature important if your battery has been neglected and suffers from sulfated plates. Big batteries take a bit more time to fill up just like your garden hose takes longer to fill your bathtub than your birdbath. Connect the charger, plug in the charger and come back next day to a battery that has been reconditioned, desulfated and fully charged but not overcharged. I connect it to my motorhome batteries and leave it for weeks to keep the batteries full. The MH batteries are 10 years old and still work fine. Yes regardless of size.

Yes it does work at full rated amps but only for very short periods. It constantly cycles out of the higher amperage because the unit cannot handle hard charges. It is OK if you are charging one battery over night or for more that 4-6 hours and need the surge to kick out a start, but it is a light duty charger. Do not expect it to charge a battery bank of 2 or more batteries.

This is a manual charger, I have used it on all most dead batteries, it should also work on those completely dead. Automatic chargers will not. As to the use as a power supply, I have not tried that, but my knowledge of electronics tells me, it will supply the voltage and current, the voltage will be unregulated and unfiltered.

It works fine charging and maintaining my 105 amp hour deep cycle trolling motor battery. With only 6 amps max charge rate, I believe that charging is easier (with less heat) on the almost 4 yr old battery, yet it is fully charged overnight.
