[TenTec] Help - Golf Cart Batteries.... Herc II ?

[Michael Melland]

I suspect my search for a lone 9420 PS for sale will be 
futile <grin>.  I'm told that a good power source for the 
Herc II are 2 ea 6V Trojan T-105 deep cycle golf cart 
batteries in series.  How long can one utilize these 
before noticing a significant drop in performance ?

I checked with Trojan Battery's technical support and they 
confirmed that these batteries are popular for this 
purpose. They told me that at 80 amps continuous draw they 
would last 100 minutes to discharge.  I'm curious given 
the typical duty cycle of radio use (30% overall I 
suspect) how long a fully charged set would last...

If I had room I'd get at least 4 and series/parallel 
connect them for longer life if necessary.

Interestingly a golf cart mfgr in my area tells me they 
have these in stock for $58 each brand new.... is that 
about right ?  Several have suggested used batteries but 
they are rare as hens teeth here in this area of 
Wisconsin.
