2A12 Battery Charger & Rejuvenator

[Faraday88]

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.

Thanks for the post first of all........
really helpful post for beginner rejuvenating small LABs with some industrial battery charger , following these steps will bring pretty much success rate..............

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

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):
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.

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.

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. :

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.

Well, as per my previous post it was discharged to 8.76 volts the next morning after 3 weeks of charging, and it's not the only battery that loses charge the next morning. 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 have used the 2a-12 charger successfully for rejuvenating small LAB's - typically 12 to 20+ A-H capacity. I have learned a number of things about this charger and most importantly it is patience and good procedure. Here are a few tips that may be of use to a first time user:
1) Always note the starting voltage of the battery for reference purposes.
2) Drain the battery with a suitable load and note the run time - I have used the c10 rate as a compromise versus waiting for c20 (20 hrs). Any of the Auto Parts chains have a wide variety of 12 volt bulbs and sockets, so one can tune discharge rates to a reasonable level - it does not have to be perfect for this purpose. I use a NAPA unit that has a 6 watt and 25 watt discharge rate. Normally the battery is drained to about 10.5 volts (use a meter) as mentioned by Aaron. Note the amp discharge rate if you have the appropriate metering.
3) Let the battery rest for a couple of hours or so and then take another voltage reading - note this voltage level.
4) Recharge the battery with the charger up to a 15.3 volt, more or less, level if possible. The steady green charger light may never come on in the beginning of the rejuve process.
5) Repeat this process a couple of times or as many as necessary to achieve a maximum A-H level.
6) You will observe a marked increase in capacity for most batteries - some batteries will not respond to this radiant First Aid due to internal difficulties.

The above charger has been used successfully on a standard (but NAPA dead) Honda battery (24 size), however it took five charge/discharge cycles to get it up to snuff (note a 55 watt halogen fog light was used for the discharge). At times it took 24 hours of charging. This battery was later used in a V6 Tacoma with no problems for a period of 6 months before being switched to a different application.

For larger batteries you will need the bigger 10 amp charger for positive results. The time required for the 2A-12 would be way too long. I will post data for successful rejuve on small batteries in the near future.

As a final note be aware that there is more to this process than meets the casual eye...

What is the lowest voltage those batteries have been discharged to?.

Well, as per my previous post it was discharged to 8.76 volts the next morning after 3 weeks of charging, and it's not the only battery that loses charge the next morning. 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.

The 2A12 is a little small to really push those batteries where they need to be - but if that is what you have, you need to cycle the batteries.
2A12 could work on, but it will take a long time.

Pick one, determine the lowest voltage it has been drained to and then drain it to maybe 0.25 volts below that voltage with a C10 or C20 rate.
Then, put it on the 2A12 immediately until it comes all the way up. After that, I'd drain it to 10 or 10.5 volts but no lower and repeat the charging.
Do that several times and the capacity should increase.

I also want to ask how long does it take to charge general use batteries, garden type, automotive with this charger? I noticed that upon charging small garden type batteries of 12 volts, the voltage goes up to about 15.15v and stays there, on some batteries it takes 30 minutes of charge (Interstate batteries), on others (EverStart) about 2 hours, however when I let them rest for 1 day or two the voltage drops to 10.5v sometimes even as low as 8+ volts, these batteries are EverStart Lawn and Garden U1-7, CA 275, and Interstate Lawn and Garden batteries 180 CA. The batteries were never used, were sitting idle in my apartment room since 2010 when I purchased them. Why do they charge so fast and discharge fast as well when idle? Shouldn't 2A12 charger detect and break the sulfation of the battery and charge them fully and not superficially? Is there a solution to this problem?

[tesla]

Aaron, or anyone else, if you know what is going on here can you comment:

I purchased a 2A12 charger last fall of 2012, charged with it my 4 Marine "deep cycle' batteries, 2 of which are EVER START 75 amp/h, reserve capacity 100, model 24DC-6 "deep cycle / trolling, and 2 are EVER START Dual Cycle "deep cycle / starting" marine cranking amps 675, reserve capacity 140, model 24dp-4. All of them are 12 volt batteries purchased in 2010, never been used and were sitting in my apartment room all this time until I charged them last fall to resting value of 12+ volts.

One of these batteries 24dc-6 started to lose charge over the last several weeks to 10.7, so I hooked up my 2A12 and charged it for 3 weeks straight, day and night, I took it off charging at 13.45 volts after 3 weeks of charging and gave it a rest overnight. In the morning the value was 8.76 volts! What is going on here?
