Best Battery Analyzer You Can Buy.
1 of 1 found this helpful In my opinion the opus bt - c3100 V 2.2 is the best Battery Analyzer on the market, yes you might see the bt - c3400 and think its newer it has to be better but it is not the 3400 just comes with a extra plug for car charging, it is also only supplies 2 Amp power, while the 3100 V 2.2 supplies 3 Amps, after this purchase i know have 7 of them and even the 1st one i bought years and years ago still charges just as fast and as accurate as my brand new ones...
