In this thread I see I need a tester: http://priuschat.com/forums/newbie-forum/73400-weird-stuff-happening-mpgs-dropping-test-battery.html 1) Can someone tell me which brand/model tester? 2) Also I need a battery maintainer-- Again, which brand/model??- I'm confused about Battery Minder, battery tender and desulfenator-types. 3) What do I need to make a start up emergency kit? I read about lanterns and lamp cords, but really am not that technically inclined. Is there something on the market I can store in the back in case I need a quick self-start and avoid waiting for AAA? 4) Anything else I need to get? Good prices are always a plus. Thanks!
