Nobody ever exploded a battery that I know > of. Mike, With all due respect, I do not care what kind of cs Jason makes. My concern is the risk and hazard his design presents to newbies. Modern Alkaline batteries have much higher energy than before. They can and will explode if left shorted, or get hot enough to cause serious burns. The original 3 nines design had a subminiature 24 Volt bulb in series with the batteries. This protected the batteries if the electrodes were shorted, and eliminated any risk of explosion or burns. Jason has removed this protection, and added one more battery to the stack. This increases the hazard. He recommends touching the electrodes to see if there is a spark. This will give newbies the impression there is no risk in doing so. There is mention of adding current regulation on some pages, but I was unable to find it. Here are a few references from the web: ------------------------------------------------------------------- "WARNING!!" "Do NOT short-circuit or disassemble your battery. A short-circuit may cause severe damage to the battery" http://www.batterymart.com/battery_faq.php ------------------------------------------------------------------- "Do not carry batteries in your pocket -- coins, keys, or other metal objects can short circuit a battery causing extreme heat, acid leakage, or an explosion." http://www.seniorworld.com/articles/a19990118165011.html ------------------------------------------------------------------- From the sci.electronics.design newsgroup: > I'm really don't know that much about 3.6V Lithium primary > batteries though. Nor do I. Except that they explode when a) short circuited and b) overheated. Still, Duracells can do that too - but they get warm first - lithiums seem to jump straight into the "danger zone". http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&safe=off&frame=right&th=8bad068ad8e9e62c&seekm=9divt5%24862%241%40uranium.btinternet.com ------------------------------------------------------------------- John Woodgate, one of the most respected engineers on the sci.electronics.design newsgroup, posted the following: > DON'T, ON ANY ACCOUNT, SHORT-CIRCUIT A BATTERY THESE DAYS. THEY > CAN, AND WILL, EXPLODE. http://groups.google.com/groups?q=alkaline+explode+group:sci.electronics.design+group:sci.electronics.design&start=10&hl=en&lr=&ie=UTF-8&group=sci.electronics.design&safe=off&selm=CSF98.11328%24X2.127959%40nnrp1.uunet.ca&rnum=11 ------------------------------------------------------------------- There are no readily-available miniature bulbs that will work at 36 Volts. The only alternative is a series resistor. Best Regards, Mike Monett -- The silver-list is a moderated forum for discussion of colloidal silver.
