Cautions

• CAUTIONS - Dangers associated with this project are mainly with the batteries, but also with wheel rotation and soldering. Be sure you understand the risks and that you take necessary precautions.

• Lithium Cell Warning! - There is a high risk of leakage, fire or explosion if you overcharge a Li-Ion cell or it shorts due to internal circuitry failing or carelessness.

Battery Comments

Comments about the nature of batteries as they pertain to the Bedini circuits in general, but to the "School Girl" (simplified) in particular.

• The Beneficial Behavior of Batteries in the Bedini Circuit - Peter Lindemann comments on what he has observed first-hand through experimental procedure.

• John Bedini on Radiant Energy and Data Collection - Discusses his methods of collecting and analyzing data relevant to his various circuit designs. Mentions battery analyzer, wave forms; discusses Tesla's radiant energy and back EMF.

• Amp Readings from Ammeter not reliable for SG - The SG input battery is providing a pulsed input (non-sinusoidal) to the coil as the transistor switches it on & off, so the reading you get from your meter is most likely not accurate. (Jim, Dec 28, 2004)

• Batteries, desulfation, impedance measurement - tools and resources links.

• Peukert Effect - Basically states that there is an exponential relationship between current draw and battery capacity: the more current drawn from the battery, the less capacity it has to power that load. The effect is a little more amplified in lead acid batteries over NiCd and NMH batteries. (Jim, Dec 28, 2004)

• Battery Chg / Dischg / Test / BK600 alternative

• Most Ah Ratings are incorrect - How to calculate more accurately to know your battery's true capacity and extend its life.

• Hard to Measure Battery Performance - comment by Dennis Turner

• Make sure there is water in your cells if your batteries use water - comment by Rick Friedrich, Nov. 13.

• Normal Battery Behavior Can be Mistaken for "Over Unity" - Virgin 12-volt lead-acid batteries increase in voltage under load (e.g. bulb) for a while after an initial rapid drop, before they gradually drop in voltage.
