To all my trusted advisors: I have a fully functional (that is until very recently) ICOM-ICA20 airband transceiver, carried as emergency backup (not yet required), to get local AWIS before start up and very occasionally, as a ground to air comm . Compared with the new handhelds its a bit on the "clunky" side but has always done what I wanted. I "inherited" the radio with my purchase of the aircraft about 9 years ago. I have no idea how old the radio is but the aircraft is 18. Enough of the background - the problem is the battery (an ICOM BP-7, 13.2 volt) - gone kaput! Radio still works fine when I connect it directly to a 12 volt source Tried to do a deal with ICOM - exchange museum piece for new unit - they didn't even see the humour in my pathetic attempt. Spoilt for choice. What to do? Replacement OM batteries do not exist. Replacement aftermarket battery (this is battery & case) does exist. Best price to date $86.20 (inc GST) + postage for a 1000 mAH Ni-MH (QLD supplier) OR A replacement battery pack insert. In the region of $70.00 (inc GST) for a 600 mAH NiCD (NSW supplier). I think the original battery was a NiCD however I dont have the original charger & use an off the shelf 12V unit or ship power.. OR I could purchase a brand new ICOM IC-A15 for $330 (inc GST) + postage (supplier Clear Prop). Smaller, lighter, no idea how it performs but assume = or better than the old unit. OR Whatever you might sugest What think you?????
