Fusionchip's Bedini Feedback to Source!!!

@ Hoppy

Bedini mentioned the need to drain and recharge the batteries several times in order to achieve a shorter recharge time on the conditioned batteries, I'm not sure if it would be useful on this experiment being that there is only one battery involved but it might be worth a try.

Good point. The two small 2.8A/hr SLA's I'm using for my current test run have been cycled and conditioned numerous times using a Bedini energiser and in much better condition than the batteries in my previous test run. I have been able to reach the 'sweet spot' but with these batteries the voltage did rise a couple of hundreth's of a volt but have stabilised and at the moment just holding very well. At the moment I'm 0.07V below start voltage. The two batteries used in my previous test run were also Bedini conditioned but drained down. The charging effect was much more pronounced with these and perhaps significantly the voltages were very unequal.

Have you tried charging a number of NiCd or Lithium rechargeables in series.
They are usually 1.25 volts each so you can combine as many as needed to get any voltage.
9 Volt rechargeables are made from six 1.25 batteries in series and are only 7.5 volts when fully charged.
So you could us 2 in series to get 15 Volts or 3 in series to get 22.5 Volts.
The reason I mention them is because they will charge and discharge much quicker then the Lead Acid batteries,
so the effect will be noticed much quicker.
Instead of having to run the setup all night you will know if the batteries are charging for sure within minutes.
Maybe these types of batteries don't work with the bedini circuit I haven't researched it.
I have never seen a very small 12 V lead acid battery, but I have seen 6 V ones that are quite small.

Hi AbbaRue,
                 
                   You bring a excellent point here, and to anwser your question, NiCd battery work very well, John used a 9v battery in his Cigar Box who ran for 7 years non stop. The best test here to know for sure is to run it on a extremely small battery like AbbaRue said. A 9v battery is usualy 150mA rated so if your setup use under 50mA i think that will be the best choice for a fullproof.

If you want to stick to lead acid there some nice little one here http://www.interstatebatteries.com/cs_estore/Products/RT/PID-SLA1010(Other+Products).aspx?dsNavigation=Nu~Part%20Number,Ns~product%20Type|101|1|,N~44-2147384810-4294967267

12v 700mAh

Yes I agree, it is important to see the charging effect go above the 'at rest' voltage using small new batteries either Nicad or LA that are reasonably well pre-charged.
