Battery load tester?

Once I learned to read a voltmeter (under many conditions) that's all I really "need".

Often worthless- I have seen many a battery read 12.8 volts, yet have near zero capacity. You *must* have a load bank for a volt meter to mean anything- the load bank could be a light or two, but by itself, voltage is meaningless.
