a battery that is able to start the engine in less than absolutely perfect conditions must be considered OK.
It is not so that a battery which starts OK is a good battery.
All that proves is that its internal resistance is low enough and that it holds enough charge for the starting.
The battery capacity could be 1/3 of the new capacity.
What we're trying to say is that if the battery has enough deliverable charge to turn the engine over normally, then PROB99 the electrical system is going to be able to power the radios when they are switched on a few seconds later
