Greetings,
With all this talk of battery load testers, I have to admit that I'm not
sure what good they will do us. Is this just a standard test where you put
a heavy load on the battery for a few seconds to see what the voltage drops
to? I think I'd be far more interested in figuring out how much current my
system draws in "alt failed" mode, and coming up with a tester that can be
set for that load, and told to time it from start to when the voltage
reaches some set point like 9V (if that's what Tracy's EC-2 pukes at).
Anyone know of a tester that will do that?
Rusty, I may be completely wrong, but the load testers do basically the
same thing more conveniently. You might wait for hours for the EC-2 and
a couple fuel pumps to pull the battery down far enough to be
meaningful. The load testers will flow big current and is already
attached to a voltmeter. Hook it up and know how healthy the battery is
in only a few minutes.
