RC-2A12-2 battery charger testimonials

The enclosed picture shows my friends electric car and 5 of the 6 Trojan batteries that were taken out and replaced. These used batteries are currently being rejuvenated using a Renaissance battery charger model RC-2A12-2 and will be put back into the car. Savings to the owner, over $600.00.

Been doing some testing on some 840 AH, lead acid glass batteries and 350 AH sealed Gel acid, this little charge has really improved there performance. Haven’t recorded any results of the load test but there is a big improvement. Just starting some testing on some 1680 AH lead acid glass batteries, each 2 volts battery weights over 300lbs, can’t wait to get testing the RC-30A12 on these big fellows.

I just got one of your RC-2A12-2 chargers and LOVE it...
It works exactly as advertised. Thanks again for a superb product,

I am very impressed with the charger! I had a 1,165 cranking amp excavator battery that wouldn't even hold a charge for a few hours. After charging for 24 hours, I connected it to my Sun Danzer refrigerator. It has been running 3 days and the voltage is still 12.5!

My car for several days was losing power on several electric functions like the lights and heater, etc. Finally one cold day the car could not start. The RC-2A12-2 charger was then used for one night restoring my battery to a useable condition. Forty days later I have not had any of those problems, even in extremely cold conditions.

Just an update for you. I recently came across a 12volt deep cycle marine battery that was showing .09 volts across the terminals. Even my Rennaissance Charger saw it as a dead short. I took a good battery and piggybacked it with the dead battery (see photo above). The Rennaissance showed good charging, and the bad battery did not short the curcuit because it was in parallel with the good battery. After 2 days the charger showed a full charge. Amazingly the deep cycle battery that had been shorted was at 12.5 volts. The first time I used it I discharged it at 1 amp per hour, it put out 9 amps, bringing it down to 12.01 volts. this battery had been sitting outside for 7 years, had never been charged since we had purchased the device it came in, we had never needed it before. I have been load cycling this battery for the past 2 weeks using it to power a 1 amp load, thru my watts up meter. Yesterday after the 6th cycle it had run for 24 hours, putting out 1 amp continuous and was at 12.14 volts. As of yesterday resting voltage is 12.86, it charges in 12 hours or so on the rennaissance charger. Each cycle has brought the battery to a higher capacity. I can now run my 1 amp load 24hrs straight with 1 battery.

Have 50 out of the 80 batteries recharged and working great. I did some on my Bedini 4 coiler hooked 6 in parallel along with a 135 ah deep cycle battery, worked great. The majority of them I have done on the powerful little radiant charger with 10 to 15 in parallel along with a car battery. All of them were at 5 to 6 volts when they were taken out of the battery backup unit and needed a good battery in parallel with it to turn on the charger. . . Load tested a few of them after a few cycles and they are right back up to their rated 9ah's; and they hold their charge really good. The Renaissance Charger is a great charger. Say thanks to John for me. Keep up the good work. It is a small step in the right direction in helping to save this planet and take back the control from those raping this earth and blinding the minds of the whole world from this energy truth as well as spiritual truths.
See attached picture, only 30 batteries to go.

11 Charge/Discharge Cycles Completed on Renaissance Charger.

See my latest results with the 12 amp hr SLA 12 volt battery. To say I am happy with the renassiance charger is the understatement of the year! I hope to do 18 cycles on the battery and call it a wrap unless it still significantly is improving as it still is now.

Just wanted to let you guys know that I received the radiant charger and have put it to work about 100% of the time I've had it already. I had an old group 58 battery that was bone dry and 0.00 voltage. I added distilled water to all the cells and took it to Autozone to have them "quick charge" it up but it kicked off on the machine after 5 minutes due to high amps on three tries. They guaranteed me it was a bad battery. This quick charger was enough to get it to 11 volts so I was happy that now I could use the radiant charger I purchased from you. I put it on and successfully charged up the battery to 12.5 volts in 12 hours. I let it sit dormant today and it ran down to 12.3 volts, I have put it back on the charger again for another 12 hours. Its happily clicking away inside. :) I have no doubt that this charger will save many more batteries like this and thus far its saved me $50 on that one battery.

My group 65 battery in my pickup would only charge up to 12.53 volts and was slow at cranking. The radiant charger is happily working its magic on it as well and easily charged it to 13.2 volts and it fires off quickly now!

I'll give you guys more definitive quantitative data and less subjective data once I have the CB2 load tester.

Thanks,

I was waiting for my truck's battery to finally die so I could test the charger on it. As the cold weather came in it was harder to start. The other day it didn't start as it was below freezing. So I got the charger out for an opportunity to test it in a real life situation. And a few hours later the battery got a second life with only one charge. No problem starting it now in weather 10 degrees lower than that day. I expect to do this every six months or so for many years to come.

battery test 100% capacity Oct 10, 2007
... With the Renaissance First Gen charger, my results are very positive. I Successfully revived 2 car batteries... (I have run it at 100% Duty Cycle since then, no problems). So I decided that I would hopefully add value to the data taking process by using the commercial professional product and restore some batteries in the process as claimed. Well I will say that there were times when I was starting to question myself for buying a $200 battery charger. But I pressed on and was most delighted, I have the print out slip from the Sun VAT45 battery tester which tested my 575CCA battery at a 580CCA rate and gave a state of charge report of 100%. ... I am a firm believer now...
Thanks,

I have been making good progress on testing the RC-2A12-1. This little beauty has been going night and day for over a month now. It has been able to revive some junk 55Ah and 80Ah gel cells (after adding a little de-mineralized water to them), as well as charging up 12 x 130Ah deep cycle/marine lead-acid batteries. ...
All the best, ...

I have been professionally charging batteries of all sizes for more than thirty years. I have even been a maintenance engineer in a battery factory and I have never seen any charger do what the Renaissance charger can do. I am doing a side by side comparison with a standard trickle charger against the Renaissance charger using two identical batteries bought at the same time and applied to a common marine application running until replaced due to batteries only being at 40% capacity due to sulfation. I borrowed the twin 50 Ah deep cycle batteries from my NAPA distributor's recycle pile for testing. The capacity was confirmed by a NAPA battery analyzer. After six charge discharge cycles I have found the Renaissance charger to use only half the amp draw as the standard trickle charger and the Renaissance charged battery last longer and longer each discharge cycle; at last count it last 3 hours and 10 minutes longer with same load applied. Let me break it down for you. It cost me half the money compared to the conventional trickle charger to get 3 hours and ten minutes longer charge and I expect much more after 12 charge/discharge cycles based on previous testing experiences. I will report again after the 12 cycles are complete...

Tom Childs restoring two golf cart batteries

Partial Reclaiming of old sulfated Daimler Chryler Corp. 500 cold cranking amps

Here are the results of the tests I ran:

I picked up this old sulfated Daimler Chryler Corp. 500 cold cranking amps from Auto Zone. Their battery tester indicated standing voltage of 11.20, but under load it dropped instantly to 2.50. Obviously, a worthless battery.

8/20/07 Started my independant testing using a Renaissance Charger 2A12.

8/20/07 Test 1: After first charge cycle, the battery read 12.67 standing voltage; it operated under load of 75 watts for a duration of 1.49 min. and the inverter dropped out at 9.74 volts terminating the test.

8/21/07 Test 2: After second charge cycle, the battery read 12.51 standing voltage; it operated under load of 75 watts for a duration of 5.0 min. and the inverter dropped out at 9.70 volts terminating the test.

8/21/07 Test 3: After third charge cycle, the battery read 12.68 standing voltage; it operated under load of 75 watts for a duration of 8 min. and the inverter dropped out at 9.74 volts terminating the test.

(okay ... so we gained 3 min. Nothing earth shattering.)

8/22/07 Test 4: After fourth charge cycle, the battery read 12.50 standing voltage; it operated under load of 75 watts for a duration of 5.09 min. and the inverter dropped out at 9.74 volts terminating the test.

(At this point I am thinking that the battery might be damaged or that the charger is not capable of actually restoring a battery like this. But I figured I would run another test.)

8/22/07 Test 5: After fifth charge cycle, the battery read 12.57 standing voltage; it operated under load of 75 watts for a duration of 7.11 min. and the inverter dropped out at 9.72 volts terminating the test.

(Maybe it is just fluctuating due to the desulfation process. Will keep runing tests.)

8/23/07 Test 6: After sixth charge cycle, the battery read 10.96 standing voltage; it operated under load of 75 watts for a duration of 170.45 min. and the inverter dropped out at 9.75 volts terminating the test.

( Now this is what I am looking for! 100 MINUTES and STILL RUNNING UNDER LOAD. keep checking back on it and it is just going and going. This is INCREDIBLE! 170.45 min total. Will do one more cycle just for kicks.)

8/24//07 Test 7: After seventh charge cycle, the battery read 10.58 standing voltage; it operated under load of 75 watts for a duration of 166.01 min. and the inverter dropped out at 9.74 volts terminating the test.

(I think I have just validated the claim here. This little charger, however small and undersize it may seem is really quite a workhorse! In just 6 cycles it has restored this battery to a remarkable level. I might add that the battery has maintained its charge for several days, no fluctuation. Seeing is believing. These kind of results are unheard of! I definately believe there are huge savings to gain using this technology. I am also looking forward to see what other products Renaissance Charge will unveil in the future. So far they are everything that they claim to be and more.)

[This battery was only run through a few cycles. It appears one of the cells was shorted, but you can see the gain in the other cells which allowed this battery to be used for a deep cycle application. RC, LLC.]
