ante Posted September 11, 2006 Report Share Posted September 11, 2006 Your best choice is to find the webpage for the battery manufacturer and you will get the correct information. Quote Link to comment Share on other sites More sharing options...
audioguru Posted September 11, 2006 Report Share Posted September 11, 2006 My hard drive is full of handling articles of Lithium rechargable batteries but I haven't selected the best article.I downloaded the good Ni-Cad and Ni-MH Applications Manuals from Energizer which are attached.The most important thing to increase their life is to not overcharge them.nickelcadmium_appman.pdfnickelmetalhydride_appman.pdf Quote Link to comment Share on other sites More sharing options...

audioguru Posted September 16, 2006 Report Share Posted September 16, 2006 so what if i leave them uncharged for long time??A lead-acid battery will get its plates sulphated and not work anymore. It must never be completely discharged.A Lithium battery will also be destroyed. It must never be completely discharged. I have some that haven't been used or charged for about 8 years and they still measure 3.8V.A Ni-Cad or Ni-MH cell is fine as long as it doesn't have a load. They self-discharge, some are dead in 3 months, others are dead in 2 years. But then they can be re-charged like new. Quote Link to comment Share on other sites More sharing options...
