From: Saturation on 26 May 2010 07:16 There are at 3 popular methods to recharge secondary batteries, and variations of these: Constant current, or galvanostatic Pulse charging Burp or Reflex charging http://corsair.flugmodellbau.de/files/elektron/NASA-II.PDF I have always taken it for granted that its known which is better, but its seems the optimal charging scheme isn't settled. If you built your own, how did you determine the frequency and pulse widths in positive, if you use pulse, and discharge, if you use reflex. Among pulse chargers I've sampled the pulse widths, and frequency all vary. http://www.powerdesignersusa.com/pdf/Tech%20Brief%20Negative%20Pulse%20Charging%20Techniques%20Myths%20&%20Facts%20-%20Final.pdf I am looking for experiences with charging methods readers find optimal and which charger you use. Most commercial chargers are either constant current or pulse. http://www.batterylifeplus.com/images/PDFs/Nguyen_2003.pdf The few that support reflex charging are often costly, in the $300-400 range. http://www.amainhobbies.com/product_info.php/products_id/145655/n/Bantam-E-Station-BC8DP-NiCad-NiMH-LiIo-LiPo-LiFe-Pb-AC-DC-Balancing-Charger http://www.westbourne-model.co.uk/fusion-l702b-pro-emperor-dc-charger-10306-0.html More on charging methods: http://www.mpoweruk.com/chargers.htm#pulse

That's normal for Philthy, but if you keep top posting you'll get flamed by a few more people. > >> >>"Saturation is all Wet " >> >>> There are at 3 popular methods to recharge secondary batteries, and >>> variations of these: >> >> >>** If one method was clearly superior for all cell types and circumstances > - >>there would be no other. >> >> You stupid trolling, fuckhead. >> >> FOAD. >> >> >> >>......
