Some people swear by alkaline batteries for their metal detectors, others use rechargeables.  What does the manufacturer recommend?  Hear the answers in this podcast.

  • One fact you don\'t consider when comparing NiMH to alkalines is the voltage curve over the battery\'s useful charge life. NiMH batteries maintain an output of 1.2 volts over just about all of their useful charge life. Alkaline batteries start off at 1.5 volts but only maintain that output voltage for the first 4 or 5 hours of use. After that the voltage starts to drop. By the time an alkaline gets to 50% remaining charge, its voltage output drops below 1.2 volts. Please refer to the graph on page 5 of thos document to see what I mean www.eznec.com/Amateur/1.5_vs_1.2_Volt_Batteries.pdf

  • Steve(s), thanks for the notes. I think the second note explains the first. I gotta respect the graphs from the ham operator (I\'m a ham myself, N9XDK), and since I recorded that show I\'ve also learned that an even better choice may well be the rechargeable alkalines. I\'m going to look into them myself. Thanks again! ---Dan, http://danhughes.net

  • I have read many books on metal detecting, but I lopved yours. I just listened to my first Pod Cast I love the show THANKS
