Is there a way to have the battery tested without actually seeing the battery. My battery does not sit under the hood but there jumping posts. Can these be used to test the battery to see if it is still good.

Hello,

Yes they can. Just put a Digital MultiMeter(DMM) across the jump terminals, or the red lead of the DMM on the positive jump terminal and the black lead on a known good ground and measure the voltage. 12.6V is 100% charged, 12.45V is 75% charged, 12.3V is 25% charged, and 12V and under is considered dead, although it should probably start your vehicle. Weird, I know, but that is how Honda of North America taught me going through their university, so that's what I pass along. I figure if Honda don't know, nobody does. Please remember also, this is a general test. To have your battery correctly checked it must be done with a battery tester that induces a load on the battery at the time it is checked. Please get back to us with what you find out.

Thanks,
Alex
