This means that a battery bank can be created at very low cost. In addition, about 50% of vehicle batteries abandoned as being incapable of holding their charge any longer, will respond to this type of charging and revive fully. Not only that, but when this method of charging is used, the batteries gradually get conditioned to this form of non-conventional energy and their capacity for doing work increases. It is possible to draw substantial amounts of energy from the local environment and use that energy to charge batteries. Note: If you are not at all familiar with basic electronics, you might find it easier to understand this chapter if you read chapter 12 first. KellyĬhapter 6: Pulse-Charging Battery Systems (green line) despite being on the desulfator for twice as long, the results were less profound than the difference between the 1st and 2nd tests, but did show gain in both capacity and voltage under load.Chapter 6 - Battery Pulse-charging systemsĪ Practical Guide to Free-Energy Devices Author: Patrick J. the battery was left on the desulfator for entire time between the 2nd and 3rd tests. the final test (which i haven't mentioned in this thread yet) occurred approximately 1 month after the second test. ![]() (red line) the result was roughly a 50% increase in capacity and roughly 0.25V higher voltage under load across the entire discharge. after the 2 week conditioning period, the battery was subjected to the same discharge test as before. (Black Line) the battery was then re-charged by the desulfator and was left attached for 2 weeks. the battery was discharged at a rate of 5A until the 10.5V cutoff threshold was reached. the charge for the initial discharge test was done on B6 clone charger 1A max with default cutoff settings. i started with a old 12V 5Ah sealed lead acid battery. The battery was left to rest for approximately 8 hours prior to initial discharge test. Maximum charge capacity was determined by the charger. ![]() The initial charge for the battery was performed by a IMAX B6 (clone) at a variable rate not exceeding 1A. The equipment to be used for the discharge tests is a West Mountain Radio - CBA II - Computerized Battery Analyzer. These amperage and voltage settings will be used for both measurements. The depleted threshold for the tests is set at 10.5V widely considered to be the total completed discharge voltage for a typical 6 cell lead acid battery under load. For this test I have chosen to discharge the battery at a rate of 1C (aka: One Hour Discharge) which for this particular battery is 5A. I feel that the best method for measuring any gain (or loss) in performance of a SLA battery is to measure the current consumption of the battery over a constant current discharge until the voltage drops below a specified threshold followed by the same test performed after the conditioning period. The underlying principle of operation of this battery is the same as any deep cycle golf cart battery. ie: as the battery increases in weight, so does the time required to pulse condition. As I understand it, results should scale proportionally with battery weight and conditioning duration. The small capacity battery was chosen for the practicality of measurement. Based on a "03" sticker attached to the bottom of the case, the year of manufacture is believed to be 2003. It is listed at 12V with a capacity of 5 Amp Hours. The test subject is a Sealed Lead Acid (SLA) battery from Power Sonic. Pretty interesting stuff! Pulse Conditioning Primer (copy & pasted from another forum) For this first experiment, I'm using the BatteryMINDer Plus Charger/Maintainer/Desulphator from Northern Tool. There is alot of experimentation and open designs for those interested in building their own. I recently tested a commercially produced Lead Acid Battery Charger/Maintainer/Desulphator on another forum and thought it might be of interest here as well. ![]()
