@daver4470: There should be plenty science available in the neighbourhood of the KSC. Did you take surface samples, EVAs, thermometer, barometer data and crew reports after landing in various biomes on Kerbin (there're many near KSC - Launchpad, Runway, KSC, Shores, Water, Grassland, Highlands)? Each surface sample (from different biome) should give you 9+ science and another 2+ when repeated. You can also do most of these when flying in lower and upper atmosphere, some even per biome. I tried and got all 5 lower tier techs + Flight Control with 3 science remaining and I visited just Launchpad, Runway, KSC and Water, maybe part of Shores (and didn't get to upper atmosphere at all). If you get to an orbit you can do crew reports per biome that you're flying over (I use VOID add-on to see which biome I'm flying over). That doesn't mean that the idea of getting batteries sooner should be thrown away, just that you should be able to get from your situation regardless .
