You are also correct regarding the charger thing.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Don and Rob are also correct to suggest to be careful with your choice of replacement batteries. IMHO, because of the vast advantages of NiMH over NiCad, I would at least call Sandersons and ask if there is any problem with that switch. I can tell you for sure that you'd have to rig up some sort of bypass of the SAT internal battery charger and use an external <STRONG><EM><U>smart charger</U></EM></STRONG> that is specifically designed for NiMH. I run a lot of lights on my bicycles that are mostly powered by NiMH packs and some Li-Ion (I have used NiCad in the past but will never, ever again because of their memory and charger problems). I buy all my stuff from </FONT><A href="http://www.batteryspace.com"><FONT face=Arial>www.batteryspace.com</FONT></A><FONT face=Arial> . BUT, please, if you have any thoughts about heading in this direction, discuss it with Sanderson - they are the ones that know those units inside and out.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Yes, all rechargeable NiCads are 1.2V. Also, all NiMH cells are 1.2V. I don't know what the SAT requires. If it originally came with four 1.2V NiCads, then yes, it would be safe to assume that 4.8V is the target.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Terry Farrell</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>----- Original Message ----- </FONT></DIV> <DIV><FONT face=Arial>> Rob,<BR>> Thanks for your valued input. Yet another question!... are ALL rechargeable<BR>> AA NiCad's 1.2 volts as opposed to non-rechargeables which are 1.5 volts?<BR>> And, is 4.8 volts (vs. 6 volts) OK for the SAT II? My last round of<BR>> batteries were totaling 4.8 volts. I had them in for a long time. Thanks<BR>> again.<BR>> Larry Trischetta<BR>> <BR>> -----Original Message-----<BR>> Your accu-tuner is an expensive instrument and part of your livelihood. <BR>> DON'T experiment with it.  Replace with the exact type of batteries that <BR>> were in there.  There should be four NiCad size AAs.  </FONT></DIV> <DIV><FONT face=Arial>SNIP <BR>> Rob Goodale, RPT<BR>> <BR>>>>List,<BR>>>>I finally got my batteries to be put in the SAT II, but now another <BR>>>>question<BR>>>>is raised; The original batteries were NiCad's. Will the charger built <BR>>>>into<BR>>>>the SAT II be compatible with NiMh batteries? It appears that they are NOT<BR>>>>compatible because of this information I found at<BR>>>>http://www.batteryuniversity.com/partone-21.htm  which states; "A charger<BR>>>>for nickel-metal-hydride can also accommodate nickel-cadmium, but not the<BR>>>>other way around. A charger designed for nickel-cadmium would overcharge <BR>>>>the<BR>>>>nickel-metal-hydride battery." However, I found an old post where someone<BR>>>>used the NiMH batteries and said they worked well in the SAT II. (I can't<BR>>>>relocate that post, or else I would repost it here). The NiMH batteries<BR>>>>supposedly have much less memory issues and last much longer. Any <BR>>>>thoughts?<BR>>>>Larry<BR>></FONT></DIV></BODY></HTML>
