Aaron, are you recommending to charge it for another 3 weeks to 13+ volts? I am afraid that next morning it will drop to low again. I am saying this because of my experience with 2-3 days charging the same battery, it would always drop low the next day. It will take me 6+ months to do cycling with this speed.
    I just heard from a different user of 2A12 that it took him 3 days to fully charge 400+A/H battery. It makes me think maybe my charger is defective? The week I purchased it, it leaked some oily liquid when heated, then plastic cracked. How much would be to service it?
    When a battery is fully charged, it is normal for it to then drop a bit, but if you're talking about a few volts or something, then it isn't holding for some reason. If the capacity is reduced, it may be just charging to that lowered capacity. You probably have checked the water level, but I want to mention it anyway. I'm not sure how a 2A12 fully charged a 400+ah batter in 3 days, but stranger things have happened.

    If you're taking about oily liquid leaking from the charger, please send us an email with details. There shouldn't be anything like that going on. If you purchased this from Tesla Chargers, please email it to the customer service email listed on the banner at Tesla Chargers | World's Most Efficient, Effective & Advanced Battery Chargers and if you can email some pics, that would be great. Something sounds strange about that. Just include details when your purchased it, etc...

    I posted another result, see here: http://www.energyscienceforum.com/te....html#post6887

    When it comes to warranty I believe I purchased 2A12 last fall from Rick Friedrick -"Going Green Saves You Money" Renaissance Charge/Energnx , but since the cover cracked and oil leaked and I had to open the unit to see what is going on. I guess you wouldn't want to have a fire in the house caused by a 2A12 charger, right? Opening the unit voided the warranty according to the manual. And support was appalling for the product that I will never buy from them again. Terrible, terrible support team. I was also disappointed that all parts in the unit are non-user-serviceable and filled in with hard epoxy, so if anything goes bad after 12 months you feel like you made a really bad investment.
    I will post some pics here for you to see soon.

    And more. Notice how oily the inside of the 2A12 is in these pictures. Notice how the epoxy has become brown in spots and it is oily as well but not so visible on pictures. I would wipe this oily liquid from outside of the box, but it would come back in a week or two. Also as you have seen, that round hole where the power supply plugs into the unit has manifested by itself, one fine day it just came off just like that, and the crack with that chunk missing also one day came off - beats me, I don't know how it happened, I don't know how oil happened to be in the box, and I don't know, how that round thing came off. The whole unit is a mess, I can't even tighten the screws anymore after I took these pics, probably thanks to the oil again, or corrosive oil maybe. And maybe I am also having a problem with charging my batteries because I got a lemon charger. :DSC04004.jpgDSC04008.jpg

    At Tesla Chargers | World's Most Efficient, Effective & Advanced Battery Chargers we have excellent customer and technical support.

    The circuit is filled with that potting compound to prevent people from reverse engineering the proprietary circuits and there is no need to have user serviceable parts when you have a warranty.

    I have seen various chargers returned to EnergenX and out of all of them, it is extremely rare that the problem is from a manufacturers defect. It can happen that there is a bad capcitor or something, but it almost never happens.

    Almost every charger that is ever returned is because the user has abused it and used it in ways that it was not designed to be used. Some people have used these to jump start their car, they use them as power supplies, etc... and then complain that they power transformer melted. I'm not saying you abused your unit - this is what we deal with occasionally.

    For your 2A12, as Tom mentioned, it sounds like a cap exploded and leaked oil but I'm not sure why you would open it if you knew that would void the warranty. Even if Rick is unable to provide you with customer service and you purchased it last fall, it would still be covered by warranty and you could contact EnergenX direct for a possible replacement unit. Hopefully Rick actually sent you a new unit when you ordered one and didn't accidentally send you one that was returned.

    Is warranty valid beyond 12 months when you spend almost $2000 for a product like 24A12? That's my point, if the warranty is not available beyond 12 months and the product breaks on the 13th month, let the consumer fix it or the company should fix it at a fare price. Otherwise it is a terrible and wasteful investment. I assume those higher priced chargers are filled in with potting compound as well as I hoped to purchase some of those units if someone could fix them after the warranty expires which is 12 months.
    I have 2 options I think here, one is to contact John Bedini and another option is to contact my bank. I find Rick and his Energenx company UNPROFESSIONAL in the aspect of handling the customer service and deeply regret I bought their unit.
    It is a well known fact that any company's legitimate existence and a real goal is to make a profit. There is no other real reason for any company to exist. That being said I stand behind every picture I posted and every word I said to be true.

    First, I want to clear something up. Energenx is the manufacturer and they are not a customer service department for Rick and his business. Rick was a distributor and was responsible for his own customer service and it is unfortunate that your requests for customer service support from Rick's company were such a bad experience.

    At Tesla Chargers, we reply to all customer service requests in 24-48 hours at the latest and we even have a phone number on our banner where you can actually reach us. Even for us at Tesla Chargers, Energenx does not provide customer service to our customers - they make the chargers/rejuvenators and we support our own customers.

    In the bigger units, depending on what the issue is, yes, some things can be replaced/repaired. I've seen a couple units that are completely fried (every component with MELTED power transformer) because someone used it as a power supply. That situation for example will not be repairable, the person has to buy a new unit and stop using it for something that it is not designed for. If it is used properly and something went wrong, then yes, it can usually be repaired but it is important that the customer does not open any unit even if the warranty is expired unless the customer is asked to open it. From a distributor or manufacturer's perspective, if a unit is opened up, there is no way to guarantee that the customer didn't short something out inside and caused the damage.

    Do this for me if you want me to try to help you out... email the customer support email on this banner (click it to make it bigger): tesla_chargers2.jpg
    Just copy and paste some of these pics and your original post about this and remind me who you are in this forum and I'll see what I can do.

    What is your point of posting a link to that company which has nothing to do with the 2A12?

    Present Industrial Battery Charger have not even known what Radiant Charging does to Batteries! yes if those shown in the website are configured in Radiant Mode, will show a world of difference to those who claim that it is the best in the world so far... but for now, it's only Bedini chargers that stay ahead in the race.
