Don't buy it for the tester/voltmeter, it doesn't read high enough for alternator testing
on September 21, 2010
Someone said the tester was just a voltmeter, so I got it because a voltmeter is adequate for a quick test at the car. But it is a voltmeter that only goes up to 12.7 volts!!!! And it has no numbers on it. Despite the fact the meter says "charging system" condition on it, it is only capable of measuring battery voltage without the car running. The meter is pegged in the green with 12.7 volts. (resting Voltage for a fully charged battery- with the car off) Which means if you believed the word "good" on the "charging system" meter, you'd think the alternator was charging, but it may not be. It only tells you if the battery is charged or not (with the car off, and no surface charge on it). The manual explains that it is "testing" the battery (though such a test is nearly useless, it is only testing the resting voltage, not the battery's condition), but it is not labeled well on the charger, and in the advertising.
Good, inexpensive manual charger, but VERY limited "tester".
UPDATE- Charger is stil working well in 2015
