Philips prp78 - UK Vintage Radio Repair and Restoration Discussion Forum

TALKINGWITHPYE · 30th May 2021, 8:47 am

Hello all I almost bought a battery on ebay which was for a Philips PRP78 radio. I am familiar with the PRP 73 74 and 76 series but never came across the PRP78. I bought one of these batteries some time ago but when I got it I found it to be longer than the ones for the PRP73 74 and 76 series does anyone know the PRP 78, I think it may be a special for the military. Any info appreciated.

Dave,

The Cadex battery management system lists the PRP78 battery as intrinsically safe, which might help throw some light on it?

Thanks Martin, I don't think the difference is Intrinsic Safety, I bought a battery some time ago which was longer than the standard prp 73 74 76 versions and when this one came up recently I did some research and found it was for a prp78 which was the model specified for the long one I have. It is a pity that batteries become unavailable but the radios are still functional. Some radios had cases which took aa cells but not the prp series.

PRP batteries had rectangular NiMH cells didn't they? I think I tried to re-stuff one once upon a time.
Eventually decided I didn't like that series of radio enough to bother with it.

Like the FM1000 it was not their finest series of sets IMHO.

Could the 78 be a 'trunked' version of the PRP series? - trunked radios usually have specific software for that purpose and are not very general-use friendly.

Even so, I would have thought it would accept the standard range of PRP battery packs.
